FAQ
Why can't my generated QR code be scanned?
Common causes: content too long (URLs should be < 100 characters), low contrast between foreground and background, logo too large covering key modules, or low error correction level. The tool auto-switches to H level when a logo is enabled.
Is there a content length limit for QR codes?
Yes. QR capacity depends on version (1-40) and error correction level. URLs should generally be under 100 characters; longer content reduces scannability.
Is my uploaded logo saved to a server?
No. The logo is processed entirely in your browser and never uploaded.
