Useful Optimization Tips for Compress Signature to 20KB
- Crop closely around your signature strokes so empty white paper doesn't consume precious byte budget.
- A resolution of 300×150 pixels or 200×100 pixels is the recommended standard across most government exam portals.
- Ensure good contrast between dark ink (black or blue) and pure white background.

Frequently Asked Questions
Why is my signature rejected by online portals?
Portals typically reject signatures if the file exceeds 20KB or 50KB, if dimensions don't match (e.g. must be around 140x60px), or if the background is grey/shadowy. TargetCompress shrinks the byte size to under 20KB while preserving sharp strokes.
Are my signatures kept private?
Yes, absolutely. Because our tool runs locally on your browser using WebAssembly and Canvas, your signature is never uploaded to any server or stored in any database.
