About QR Cat
QR Cat is a small team making free online QR code tools, and one of the Cat Tools family. We believe a tool should be honest — no expiry traps, no quietly harvesting your data, no ads stamped on your code.
Four promises
- Free forever — no trial window, no “your code expired, pay to keep it,” every feature open.
- Never expires — we make static codes; the content lives in the pattern itself, so your code scans even if we go offline.
- Local-first — the QR is built in your browser; your content is never uploaded, never tracked.
- No watermark, no sign-up — download and go, no logo on your code, no email wall.
How it works (the honest version)
A lot of “free” QR sites hand you a dynamic code: the code is just a short redirect link, and the real content lives on their server. Stop paying and the link dies — the code you printed on a flyer, menu or business card becomes a dead square.
QR Cat does the opposite. We use open-source libraries to encode your content into a static code, right in your browser. The black-and-white modules are your URL / WiFi / contact card — no server hop in between, and decoding happens locally too. Because there's no server cost, “free forever, never expires” isn't a marketing line — it's just what the architecture allows.
The Cat Tools family
QR Cat shares a team and a philosophy with Compress Cat (PDF tools) and Design Cat (design assets): do one small thing honestly and well, keep it good-enough, and never trade your experience for a quick buck.
Frequently asked questions
Is QR Cat really free forever?
Yes. Your QR codes are generated locally in your browser, so our server cost is essentially zero — there's no trial to expire. Generating, recoloring, adding a logo, exporting PNG / SVG and decoding from an image are all free, with no sign-up.
Is my content (URLs, WiFi passwords, contact details) uploaded?
No. The QR code is computed on your device. Whatever you type never touches our servers, and we don't track or store it. Decoding an image happens locally too.
Will the QR codes I make stop working later?
No. We generate static codes — your content is encoded directly into the black-and-white pattern, with no server redirect in between. Even if QR Cat shut down tomorrow, the codes you printed would still scan.
How is QR Cat related to Compress Cat and Design Cat?
They're sibling tool sites in the same Cat Tools family, built by the same team on the same honest principles: Compress Cat for PDFs, Design Cat for design assets, QR Cat for QR codes.
