Is there a capacity limit for generated QR codes?

Yes. QR codes can encode up to about 2,900 characters (more in numeric mode). Longer content makes denser codes. Keep it concise for scannability.

Can I generate QR codes with a logo?

The current version does not support inserting logos in the center. We recommend adding logos with an image editor afterward, being careful not to cover too much data area.
