Frequently asked questions
- Which error correction level should I use?
- M is a good default. Use H if the code may be partially covered or printed small; L keeps the matrix simpler for long URLs.
- Can I generate a logo in the center?
- This tool outputs a standard matrix PNG. Overlay logos in design software and raise error correction if needed.
