Before you make one
Use high error correction (H) when adding a center logo.
The renderer clamps logo size based on error correction and can add a light backing.
A logo can still reduce scan reliability. Test the exported code on actual devices.
Example to adapt
Start with a square, high-contrast PNG or WebP mark and a short web link. Fine detail may disappear at small print sizes.
Questions and answers
Is my logo sent to a server?
No. The browser reads the image locally and embeds it in the generated file.
Can a logo make a QR unscannable?
Yes. A logo covers modules. The tool applies a size limit, but test the finished export.
Which file formats can I use?
The studio accepts PNG, JPEG, and WebP within its upload-size limit.
