Why resize your signature to exactly 10–20KB?

💡 Pro Tips for 10–20KB Signatures
- Sign with a dark black or blue pen on clean white paper for the clearest digital result.
- Crop tightly around your signature before uploading — less whitespace means better compression.
- Use natural light and avoid shadows when photographing your signature with a phone.
