QR code generator

ContentStudio's free QR code generator creates QR codes for URLs, text, contact information, email addresses, phone numbers, and SMS messages. Enter your data, customize the appearance, and download the QR code in your preferred format. No account required, no email needed. For teams running social media campaigns that include QR codes in physical and digital materials, ContentStudio handles the publishing workflow alongside the tool.

How to Create a QR Code for Social Media

1. Select the data type: URL, plain text, email, phone number, SMS, or contact card.
2. Enter the information you want to encode — for a URL, paste the full address including https://.
3. Customize the QR code: choose colors, adjust the pattern, and add a logo if needed.
4. Click Generate to produce the QR code.
5. Test the code with your smartphone camera before downloading.
6. Download in your preferred format: PNG for digital use, SVG for print, PDF for documents.

How to Make a QR Code for a Link

A URL QR code encodes a web address so that anyone who scans it goes directly to that page. To create one:

1. Select URL as the data type.
2. Paste the complete URL including https:// into the field. A URL without the protocol prefix may not encode correctly.
3. Generate and test by scanning with a phone camera or QR scanner app — the link should open in the device's browser.
4. Download and use in print materials, presentations, packaging, or digital assets.

Using UTM parameters on QR code URLs: For campaign tracking, add UTM parameters to the URL before encoding it. For example: https://yoursite.com/page?utm_source=print&utm_medium=qr_code&utm_campaign=event_2026. This allows your analytics platform to report how many visits came from the QR code specifically.

QR Code Formats:

The download format determines how the QR code can be used:

PNG: A raster image file. Best for digital use — websites, emails, social media posts, and presentations. PNG quality decreases if the image is scaled up beyond its original dimensions.

SVG: A vector format. Best for print materials — flyers, posters, packaging, and large-format printing. SVG files scale to any size without quality loss. Use SVG whenever the QR code will appear in print.

PDF: A document format. Useful for embedding QR codes in contracts, forms, and documents that will be shared or printed as PDFs.

For any QR code that will be printed, download SVG or use a high-resolution PNG (minimum 300 DPI equivalent for the intended print size).

QR Code Customization: Colors and Logo

QR codes do not have to be black and white. Customization options on the generator include:

Colors: Change the foreground color (the dark modules) and background color. Keep sufficient contrast between foreground and background — low contrast codes (light grey on white, or dark blue on black) may fail to scan. Test any color-customized code with multiple devices before finalizing.

Logo: Add a logo to the center of the QR code. QR codes have built-in error correction that allows a portion of the code to be obscured while remaining scannable. The logo should not cover more than 30% of the code area for reliable scanning.

Pattern and corner styles: Some generators allow adjusting the shape of the modules (square, rounded, dots) and the corner finder patterns. These changes affect visual style while maintaining scan functionality.

Always test customized QR codes across multiple scanner apps and devices. A code that scans on one app may fail on another if contrast or error correction level is set too low.
