Everything for QR codes in one place - make them, read them and test them.
Design a code with your logo and colours in the QR Code Generator, read any code from your camera or a screenshot with the QR Code Scanner, and grade it before printing with the QR Code Checker.
All three run on our own QR engine, right in your browser - nothing is uploaded.
Nothing here matches "".
Our tool shelf is big, though. Try the site search or .
Most QR sites wrap the same open-source library in a form. We wrote our own QR engine from the standard up: the encoder packs your content into the smallest possible code, and the decoder reads codes from real photos - tilted, blurry, inverted or mirrored.
Because one engine does both jobs, the tools work together. The generator scan-tests every design live, the scanner shows how healthy a code is, and the checker draws a damage map of every module. Codes are static, so they never expire and there are no scan limits.
Logo, shapes, frames, PDF with crop marks, bulk from CSV
QR, Micro QR and barcodes, short-link reveal
Grade A-F, damage map, live camera test
Runs in your browser, nothing uploaded
Make a WiFi code in the QR Code Generator, add a "Scan me" frame and print it for your cafe, office or Airbnb.
Drop the print file into the QR Code Checker. Aim for an A, then scan one printed proof with two phones.
Scan a code on a parking meter or flyer with the QR Code Scanner - it shows the real site and warns about short links and look-alike addresses before you open anything.
Put your contact details in a vCard code, then match its colours to your brand with the Color Contrast Checker.

Start with the QR Code Generator, read codes with the QR Code Scanner and test them with the QR Code Checker - they hand codes to each other with one click.
Yes - all three are free, with no sign-up, no watermark and no scan limits. The codes you make are static, so they keep working forever.
No. Codes from the QR Code Generator store your content inside the pattern, not on our servers, so there is nothing that can expire or be switched off.
Open the QR Code Scanner and paste the screenshot with Ctrl+V (Cmd+V on a Mac), or upload it. It works on computers without a camera.
The QR Code Scanner never opens links by itself. It shows the real site name first and warns about short links, look-alike addresses, app downloads and payment pages.
Yes. The generator clears the centre for your logo and raises error correction to H, and its live scan check warns you if the logo gets too big.
Upload the print file to the QR Code Checker. It grades the code from A to F and explains every problem - contrast, white border, size, density and damage.
Yes. The QR Code Scanner reads EAN-13, EAN-8, UPC-A, UPC-E and Code 128 barcodes, plus Micro QR codes - and every code in a picture at once. Books show their ISBN, products get a one-click lookup.
No. Our own QR engine runs in your browser, so your content, logos, camera frames and screenshots stay on your device.
