1. What You Need Before You Start

The good news is that there is very little preparation required before opening a QR code generator. That said, having the following things ready will make the process faster and more intentional.

The URL or information you want to encode. QR codes most commonly link to a web address, so have the full URL ready before you start. This might be a website homepage, a specific landing page, a social media profile, a digital menu, a feedback form, a payment link, a video, or a downloadable PDF. Whatever the destination, copy the exact URL from your browser so there are no typos in the final code. For non-URL content such as contact details or plain text, have that information ready to paste as well.

Your brand assets if you plan to customize. If you want your QR code to reflect your brand, having your hex color codes, logo file, and any brand guidelines on hand before you start will save time. A logo file in PNG format with a transparent background is ideal for embedding into the center of a QR code without a visible white box around it.

Your intended use case and output format. Knowing where the finished QR code will be placed helps you make better decisions about size, file format, and customization. A QR code going onto a high-volume printed poster needs a different file format than one being embedded in a digital email signature. Think through your use case before downloading so you choose the right export settings the first time.

A desktop or mobile browser. Online QR code generators run entirely in the browser with no software installation required. Any modern browser on any device will work.

2. Open the QR Code Generator and Enter Your URL

Open your chosen online QR code generator in a browser. The interface for most tools in this category is deliberately minimal: a text field where you enter your URL or content, a generate button, and a live preview that updates as you make changes.

Click into the URL input field and paste or type the full web address you want the QR code to link to. Double-check the URL carefully before proceeding. A single character error in the URL will cause the QR code to link to a broken or incorrect destination, and this mistake is easy to miss once the code is in use at scale on printed materials.

For non-URL content such as plain text, a phone number, an email address, or contact card information, enter that content in the same field using the appropriate format supported by the tool. Most modern QR code generators support multiple data types beyond just URLs, though web links are by far the most common application.

Once your URL or content is entered, click the generate button. The QR code image will appear in the preview area almost instantly. At this point you have a functional QR code, but you have not yet customized it or chosen your download format.

3. Customize the Style and Color of Your QR Code

A basic black-and-white QR code is perfectly functional, but most online generators offer customization options that let you personalize the visual appearance of the code to align with your brand, your design aesthetic, or the material it will be placed on. This step is optional but worth taking a few minutes to explore.

Changing the foreground and background colors

The foreground color refers to the dark module squares that make up the QR code pattern itself. The background color is the light area behind those modules. By default these are black and white respectively, but both can be changed to any color you choose. If you have brand colors, enter your hex codes into the color picker fields for precise matching. The most important rule when changing colors is to maintain strong contrast between the foreground and background. A light foreground on a white background, or a dark foreground on a dark background, will prevent the code from scanning reliably. When in doubt, always err toward higher contrast.

Selecting a dot or module style

Some QR code generators allow you to change the shape of the individual modules within the code pattern from the standard square to rounded, circular, or other geometric forms. This can give the code a softer or more contemporary visual feel without affecting its scannability as long as the changes stay within the tool's tested parameters. If you change module styles, always test the resulting code by scanning it with a smartphone before distributing it.

Adding a frame or border

A frame placed around the outside of the QR code provides additional visual context and can include a short call-to-action label such as "Scan me," "Visit our site," or "Learn more." Frames help draw attention to the code on crowded printed materials and clearly signal to viewers that the code is meant to be scanned. Most tools offer a selection of frame styles and allow you to edit the text label within the frame.

Embedding a logo

Many online QR code generators allow you to place a logo or icon in the center of the code. QR codes are designed with built-in error correction that allows a portion of the pattern to be obscured without losing scannability, and the central area is specifically reserved for this purpose. Upload your logo as a PNG with a transparent background for the cleanest result. Keep the logo small relative to the overall code dimensions, as a logo that is too large will cover too much of the data pattern and prevent scanning. A logo occupying no more than roughly 20 to 30 percent of the total code area is a safe guideline.

Always test after customizing: After making any customization changes, scan the resulting code with a smartphone camera before moving forward. This confirms that the code is still working correctly after your visual adjustments.

4. Test Your QR Code Before Downloading

Before downloading and distributing your QR code, testing it thoroughly is one of the most important steps in the process and one that is often skipped. A QR code that looks correct on screen may still fail to scan due to color contrast issues, logo placement that covers too much of the data pattern, or problems with the underlying URL.

Open the native camera app on a smartphone and point it at the QR code preview on your screen. Hold the camera steady and wait for the code to register. When the destination URL appears as a banner or notification, tap it and confirm that it opens the correct page. Repeat this test on a second device if possible, as different camera apps and smartphone models can have slight differences in their QR code reading capabilities.

If the code does not scan reliably, check the following. The contrast between foreground and background colors may be too low. The logo in the center, if any, may be too large and covering too much of the data pattern. The URL may contain a typo. Adjusting any of these factors and retesting should resolve most scanning issues.

5. Choose Your File Format and Download

Once your QR code is customized and tested, the next decision is which file format to download it in. The right format depends on how and where the QR code will be used.

PNG

The most versatile format and the right choice for the majority of use cases. PNG supports transparent backgrounds, making it easy to place the code cleanly over any background. Suitable for both digital and print use. Always download at the highest resolution available.

JPEG

A compressed format that does not support transparent backgrounds. Adequate for general sharing or embedding in documents where the code sits on a white background, but not the preferred format for professional print use or designs with non-white backgrounds.

PDF

The recommended format when the QR code will be submitted to a professional printer or placed in a high-resolution print layout. PDF preserves full image quality at any output size and is the standard format for print production workflows.

SVG

A vector format that scales to any size without quality loss. Ideal for responsive digital use and print workflows where the final size is unknown at design time.

After downloading, check the file on your device to confirm it looks correct and that the transparent background is intact if you selected PNG with transparency.

6. Place Your QR Code Into a Larger Design

For many projects, the downloaded QR code is not the final deliverable on its own. It needs to be placed into a poster, flyer, business card, invitation, social media graphic, or another designed piece. Open your design project in whatever tool you are using and insert the QR code image file.

Think about size and placement carefully

The QR code needs to be large enough to scan reliably at the distance from which viewers will encounter it. For print materials read at arm's length, a minimum size of approximately 2 x 2 centimeters is the baseline, but larger is always better for reliability. For materials read from a greater distance, such as event signage or retail displays, scale the code up significantly. A general guideline is that the scanning distance should not exceed ten times the width of the printed code.

Position the code where it will be noticed

A QR code placed in an obvious, prominent location on a design will get far more scans than one tucked into a corner. Bottom right or bottom center of a flyer or poster are common and effective placements. On a business card, the back is a natural location that keeps the front clean. On packaging, a visible panel that faces outward when the product is shelved or displayed is ideal.

Add a short call-to-action near the code

A QR code on its own gives viewers no immediate context for what will happen when they scan it. A short label nearby, such as "Scan to book a table," "Scan for our menu," "Scan to follow us," or "Scan to shop," dramatically increases the likelihood that people will engage with the code. The call-to-action should be concise, directly relevant to the destination, and placed close enough to the code that the association is immediately obvious.

Maintain a clear zone around the code

QR codes require a quiet zone, which is a margin of empty space around the outer edge of the code pattern, to scan reliably. Do not allow other design elements such as text, images, or graphic accents to overlap or sit right up against the edges of the code. Most downloaded QR code images already include this quiet zone built in, but be careful not to crop or trim it when resizing.

7. Prepare Your QR Code for Print Use

If your QR code is going onto any printed material, a few additional considerations apply beyond the steps above.

Verify your resolution

For professional print quality, your QR code image should be at a minimum of 300 DPI at the size it will be printed. Most QR code generators produce PNG files at a resolution appropriate for screen use, which may be lower than the print standard. If you are using a PDF download, this concern is less relevant as PDF is resolution-independent. If you are using PNG, check the pixel dimensions of your downloaded file and confirm they are sufficient for the intended print size at 300 DPI.

Test the printed version

Printing introduces variables that do not exist in digital use. Ink absorption, paper texture, and print quality can all affect the scannability of a QR code. Before committing to a large print run, produce a single test print at the final intended size and test the code by scanning it. This catches any print-related scanning issues before they become a costly problem across many copies.

Consider the surface

QR codes on highly textured surfaces, glossy materials with heavy glare, or irregular shapes may scan less reliably than codes on flat matte surfaces. If your QR code is going onto an unusual substrate such as fabric, foil, or a heavily textured label, test the scanning performance of a physical sample before full production.

Keep a record of the URL

For static QR codes, the destination URL is permanently embedded in the pattern and cannot be changed after the code is created. Keep a record of exactly which URL each code links to, particularly if you are managing multiple QR codes for different purposes. This documentation will save significant time if you ever need to verify what a code does or troubleshoot a scanning issue.

8. Tips for Getting the Best Results

Always maintain strong contrast. The single most common cause of QR codes that fail to scan reliably is insufficient contrast between the foreground modules and the background. Light on light or dark on dark combinations should always be avoided regardless of how visually appealing they may look in a design context.

Test on multiple devices. Different smartphones scan QR codes differently. What scans instantly on one device may take several attempts on another. Testing on at least two or three different devices before distributing your code gives you greater confidence in its reliability across your audience.

Keep the URL clean and stable. If possible, use a clean, permanent URL that is not likely to change. A very long URL increases the complexity of the QR code pattern, which can slightly reduce scanning reliability at smaller print sizes. If you are working with long URLs, consider using a URL shortener to reduce the encoded string length.

Size up when in doubt. A larger QR code is always more reliable than a smaller one. If you are unsure whether a code will scan at the size you are planning, increase the dimensions. The visual impact of a larger code on a design is almost always preferable to a code that frustrates users by failing to scan.

Include a visible URL as a fallback. On print materials where space allows, printing the short URL in small text beneath the QR code gives users a manual alternative if they encounter difficulty scanning. This is particularly valuable for materials aimed at audiences less familiar with QR codes.

9. Frequently Asked Questions

Do I need to download any software to create a QR code online?
No. Online QR code generators run entirely in a web browser and require no app download or software installation. Any device with a modern browser and internet connection can access and use these tools, including smartphones, tablets, and desktop computers.
Can I create a QR code on my phone?
Yes. Most browser-based QR code generators work fully on a mobile browser, allowing you to generate, customize, and download a QR code entirely from a smartphone. No dedicated app is required, though dedicated apps are available on most platforms if you prefer them.
What types of content can a QR code link to?
The most common use is linking to a website URL, but QR codes can encode a variety of data types. Common applications include website and landing page URLs, social media profiles, digital menus, PDF downloads, contact cards in vCard format, phone numbers, email addresses, plain text, payment links, app download links, feedback forms, and video content. Essentially anything that has a URL or can be expressed as a compact data string can be encoded into a QR code.
Do QR codes expire?
Static QR codes, in which the destination is permanently embedded in the code pattern itself, do not expire. They will function as long as the destination URL remains active and the code is physically intact. Dynamic QR codes, which use a short redirect URL managed by the generator platform, may expire if the platform requires a paid subscription to maintain active redirects. If you are creating codes for long-term use on printed materials, confirm whether the tool you are using produces static or dynamic codes and whether any ongoing subscription is required to keep them active.
What is the difference between a static and a dynamic QR code?
A static QR code has its destination permanently encoded in the pattern. Once created, the URL cannot be changed without generating an entirely new code. Static codes work without any dependency on the generating platform remaining active. A dynamic QR code uses a short redirect link that can be updated after the code has been printed or distributed, allowing you to change the destination without creating a new code. Dynamic codes typically require an active account with the generator platform and may require a paid plan for continued redirect functionality.
Can I add my logo to a QR code?
Yes. Many QR code generators support logo embedding, placing your brand icon in the center of the code. QR codes include built-in error correction specifically designed to allow a portion of the pattern to be covered without affecting scannability. Keep the logo small relative to the overall code dimensions, use a PNG file with a transparent background for the cleanest result, and always test the final code by scanning it after adding a logo to confirm it still works reliably.
Can I change the colors of my QR code?
Yes. Most modern QR code generators allow you to customize both the foreground color of the module pattern and the background color. The critical requirement is maintaining strong visual contrast between the two. Low contrast combinations, such as light gray on white or dark navy on black, will prevent reliable scanning even if the design looks intentional. Always test a color-customized code before distributing it.
What is the best file format to download a QR code in?
For most uses, PNG is the best format because it supports transparent backgrounds and produces sharp results at typical sizes. For professional print use, PDF is the preferred format as it is resolution-independent and works cleanly at any output size. JPEG is acceptable for general sharing but does not support transparency and uses lossy compression that can degrade image quality slightly, so it is not recommended for print applications.
How large does a QR code need to be to scan reliably?
A minimum printed size of approximately 2 x 2 centimeters (about 0.8 x 0.8 inches) is the general baseline for close-range scanning. For materials scanned from greater distances, the code should be proportionally larger. A practical rule of thumb is that the maximum reliable scanning distance is approximately ten times the width of the printed code. For event signage or retail displays intended to be scanned from across a room, the code should be significantly larger than the minimum.
Can I use a QR code for commercial purposes?
Yes. QR codes generated through online tools can be used freely for commercial purposes including marketing campaigns, product packaging, business cards, menus, signage, brochures, and any other commercial context where you need to direct customers or clients to a digital destination. Check the terms of service of the specific generator tool you use to confirm commercial use is permitted under the plan you are on.
What should I put near my QR code to encourage people to scan it?
A short call-to-action phrase placed close to the code significantly increases scan rates. The best calls to action are specific and tell the viewer exactly what will happen when they scan: "Scan to book a table," "Scan to view our menu," "Scan to follow us on Instagram," or "Scan to claim your discount" are all more effective than a generic "Scan here." The call-to-action should be positioned directly above or below the code and set in a font size and weight that is easy to read at a glance.
How do I scan a QR code?
Open the native camera app on a smartphone, point it at the QR code, and hold it steady. Most current iOS and Android devices detect QR codes automatically through the camera app and display a banner or notification with the linked URL. Tap the banner to open the destination in a browser. No separate scanning app is required on most modern smartphones, though dedicated scanner apps are available if your device does not support native scanning.
