❓ FAQ

What's the maximum content length?

QR codes can store up to 4,296 alphanumeric characters, but ~500 is practical for reliable scanning.

Can I add a logo to the QR code?

Not directly in this Actor. Generate with H error correction, then overlay a logo covering up to 30% of the center.

Why isn't my QR code scanning?

• Increase size for print materials
• Use H error correction for durability
• Ensure sufficient contrast between colors

What image formats can be read?

PNG, JPEG, WebP, and most common formats supported by Sharp.
