Preflight review
QR readability checks
Generate a QR code to review contrast, quiet zone, module size and density.
Correction guide
Choose an error correction level
M is a balanced default. Q or H recovers more damage but creates a denser code. L fits more data with less recovery.
Production guidance
Make QR codes easier to scan
Use dark modules on a light background, keep at least four modules of clear space, and test the final printed or displayed code on several devices.
QR code generator FAQ
Is QR content uploaded?
No. Payload construction and export happen locally in your browser.
Which correction level should I use?
M is balanced. Q or H tolerates more damage but is denser.
Why did the code become dense?
Long content and stronger correction require a larger matrix.
Does preview guarantee scanning?
No. Test the final size, material, lighting and target devices.
