Where is my QR data processed?
Processing happens locally in your browser. The tool does not send your input to a backend service.
Can I download the QR code image?
Yes. Use the download buttons to save PNG, SVG, or PDF for web, print, or sharing.
What size should I use for printing?
For most cases, start with at least 2 x 2 cm (about 0.8 x 0.8 in) and test scan distance before final print.
Why does a QR code sometimes fail to scan?
Common reasons are low contrast, tiny size, cluttered background, or not enough quiet space around the code.
Is the scanner safe to use?
The scanner page runs local checks and flags suspicious patterns before opening links, helping reduce risky scans.
