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.

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.
