A QR code generator that makes codes people can actually scan

Yes, and not in a "free for 14 days" way. Every code type, every design option and every export format is free, with no sign-up, no watermark and no limit on how many you create. The site is paid for by the adverts you can see labelled on the page. See how QRilo is funded.

No. Your content is encoded into the pattern itself, so there is no redirect service in the middle and nothing to renew. A code printed today will still resolve in ten years, provided the destination it points to still exists. If you delete your website, of course, the code will lead nowhere — that part is up to you.

Yes. Codes you generate here can be used in commercial work — menus, packaging, business cards, vehicle wraps, paid advertising. There is no attribution requirement and no licence fee. Be aware that "QR Code" is a registered trademark of DENSO WAVE, but the standard itself is free to use; using the symbol is fine, using the phrase in a product name is not.

Nine times out of ten it is one of four things: too little contrast between the code and its background, no clear margin around it, a logo that covers more of the symbol than the error-correction level can repair, or a print size so small that the modules blur together. QRilo checks all four as you design and blocks the download when something is genuinely unsafe. For the full diagnostic, read why QR codes fail to scan.

A reliable rule is the 10:1 ratio — the code's width should be at least one tenth of the distance from which it will be scanned. For a table tent read at 30 cm, that means roughly 3 cm wide. For a poster read across a room at 3 m, at least 30 cm. Add more size for dense codes, which carry longer content.

Dynamic codes route through a short URL, which lets you change the destination later and count scans — genuinely useful for a large campaign. The trade-offs are real though: the code depends on someone else's server staying online and paid for, it usually needs a subscription, and the code itself carries less of your actual content. For anything printed once and used for years, a static code like the ones here is the safer choice.

Yes, and QRilo enforces the rule that protects you: logos require error-correction level H, which allows about 30% of the symbol to be lost and still recovered. The logo is capped so it never hides more than that budget allows, and you get a warning as you approach the limit. Keep the logo under a quarter of the code's area and test the printed result with two different phones before ordering 5,000 business cards.

Generating a code needs no internet at all — the whole engine is downloaded with the page. Scanning a Wi-Fi or contact code also works without a connection, because the data lives in the pattern. Only codes that point at a web address obviously need connectivity to fetch that page.
