Getting a clean signature scan
Sign on plain white paper with a dark pen, photograph or scan it in good light, then crop tightly before resizing for the cleanest result.
Meeting exact requirements
Many portals specify both pixel dimensions and a maximum file size for signatures. Resize first here, then use Compress Signature to 20 KB or 50 KB to meet a file size limit.
Tips for the best result
- Crop as close to the signature as possible before resizing to avoid empty margins eating into your size budget.
