FAQ
Why is scan success low in some cases?
Common reasons are overly long content, poor color contrast, or too small output size. Increase contrast and use a higher error correction level.
Does a center logo affect scanning?
Yes. Keep the logo moderate in size and consider using level Q or H.
PNG vs SVG: which one should I use?
PNG is great for direct publishing and sharing, while SVG is better for lossless scaling in print and frontend use.
