FAQ
What does error correction level mean?
Higher levels (Q, H) embed more redundancy so the code still scans even if part is damaged. They produce slightly bigger codes. M is default; H is recommended for stickers.
Can I scan a QR code with this tool?
The current version generates QR codes only. A camera scanner is on the roadmap.
