Frequently asked questions

Yes — every tool on this page is free and needs no account. They run in your browser, and nothing you enter or upload is stored on our servers (the safety checker only sends the link you ask it to trace).

Yes. Every tool is built mobile-first — scanners use your phone camera, and calculators, checkers, and generators are designed for one-handed use on mid-range devices.

Almost everything runs on-device: QR decoding, barcode reading, image analysis, and all calculators never leave your browser. The one exception is the QR safety checker, which traces the destination link from our server so your device never touches a suspicious site.

These tools create and check static codes and links. A QRA workspace adds dynamic QR codes — change the destination after printing, see scan analytics by time, city, and device, add your branding, and manage everything from one dashboard with a 14-day Pro trial.

Need to edit your QR code after printing?

Dynamic QR codes let you change the destination anytime — no reprinting — and show you every scan: when, where, and on which device. Try the full QRA studio free for 14 days.
