Is this QR code generator really free?
Yes — generating, customizing, and downloading QR codes is completely free, with no account, signup, or watermark.
Do my QR codes expire?
No. Every QR code this tool makes (except Multi-URL and dual-platform App links) encodes your content directly, so it works for as long as the destination link or content is valid — there's no subscription or expiry tied to this tool.
What's the difference between PNG and SVG?
PNG is a fixed-resolution image, good for most uses. SVG is a vector file that stays sharp at any size, which is better if you're printing the code very large, like on a poster or banner.
Will the QR code still scan if I change the colors?
Yes, as long as there's enough contrast between the foreground and background colors. Very light foreground colors or low-contrast combinations can make a QR code harder for some scanners to read — the built-in presets are chosen to scan reliably.
How does the "Multi-URL" option work without a server?
The QR code encodes a link back to this site with your list of URLs built into the link itself. When someone scans it, their browser picks one of your URLs at random and redirects — no database or account needed on our end.
Can I upload a PDF to be hosted here?
No — this tool doesn't store or host files. For the PDF type, paste a link to a PDF you've already uploaded elsewhere (Google Drive, Dropbox, your own website), and the QR code will point straight to it.
