QR Code Generator

Text in, QR code out. PNG or SVG. No tracking.

How it works

Free QR code generator that runs entirely in your browser — no signup, no expiration, no tracking pixels in the resulting code. Generate static QR codes for URLs, plain text, or any content. SVG output is recommended for print (infinite scaling); PNG is better for chat / email / social.

Verify it yourself. Open DevTools → Network → run a conversion. The only requests you'll see are the page assets — your file never leaves this tab.
On mobile? Downloaded files save to your Files app (iPhone/iPad) or Downloads folder (Android), not your photo library. To move an image to Photos, open it from Files and tap the share button, then "Save Image." This is how all browser downloads work — not a Bytario limitation.

FAQ

Do these QR codes expire?

No. Many "free QR generator" sites give you a redirect URL that they control and can disable later. Bytario embeds the URL or text directly into the QR code — once generated, it works forever, regardless of whether bytario.com is online.

What error correction level should I use?

M (medium, ~15%) is the default and works for most use cases. Use H (~30%) if the QR will be printed on a surface that might get damaged or partially obscured (stickers, T-shirts, posters).

Why is SVG better for print?

SVG scales infinitely without quality loss. A QR code printed at 1cm or 1m from the same SVG is equally crisp. PNGs are pixel-bound — fine for screens, blurry when scaled up for posters.
