Decode QR codes from uploaded images
Screenshots and photos work—lighting and blur matter more than file format.

Key takeaways
- Crop to the code region when photos include busy backgrounds.
- Treat decoded URLs as untrusted—verify domain before opening.
Support workflow
Ask users for a cropped screenshot of the code, not the entire desktop.
Compare decoded text with the URL you expected from QR Generator during campaign QA.
FAQ
Why did parsing fail?
Motion blur, glare, or low contrast are common—retake closer with even lighting.
Does this upload my image?
File-based parsing uses server processing—only upload non-sensitive QR test images.
