QR Code PNG vs SVG: Which Should You Download?

Choose PNG when you need a ready-to-use image for a post, slide or document. Choose SVG when a compatible design or print app needs to scale the QR code. Clusstr’s free QR code generator downloads both formats without signup.

PNG vs SVG for a QR code

The URL encoded in the QR pattern is the same in both formats. The format changes how the image is stored and scaled, rather than where it sends a scanner.

How to generate a free QR code and download it

1. Open the free QR code generator and paste a complete public HTTP or HTTPS website URL.
2. Select Generate QR code. The preview shows the URL encoded as a static QR code.
3. Download PNG or SVG. There is no account or payment step; both downloads include Clusstr branding.
4. Place the complete image in your design. Keep the white scanning margin and the logo/footer visible.
5. Scan the final design with your phone and open the destination before sharing or printing a batch.

How to check a QR code before printing

There is no single print size that works for every URL, viewing distance and surface. Longer URLs can make a denser pattern. Print one proof at the actual size and test it from the distance people will use.

• Keep dark modules on the supplied white background. Don’t place another graphic over the code.
• Preserve the white margin around all four sides. The Clusstr footer belongs below that scanning area.
• Avoid screenshots that blur the square edges. Use the downloaded file in your design app.
• Test the finished print or exported document, not only the generator preview.
• Confirm that the website opens without a private account or expired access token.

For the technical background, DENSO WAVE explains how module size affects readability and why a QR code needs a clear margin.

Do free QR codes expire?

The static QR code generated by Clusstr has no built-in expiration date. The URL is stored in the image itself. Clusstr doesn’t add a subscription gate to a QR code that points directly to your website.

The destination still needs to work. If the website goes offline, a document link expires, or the code points to a paused short link or unpublished page, the QR image cannot fix that destination.

Can you change the destination or track scans?

A static QR image keeps the URL it was generated with. If you enter a different URL, generate and distribute a new image. Clusstr’s generator doesn’t collect scan counts.

If you want link-click trends, create a free short link with click tracking first, then generate a QR code for it. That records redirect requests, not every camera scan or unique person. Standalone short-link destinations are fixed, and pausing the link stops that QR destination from opening.
