Compress Signature to 20KB – Questions & Answers

Why did my previous signature get rejected by the portal?
Most phone camera photos are 2MB–5MB in size. Portals have hard limits (like 20KB) and instantly reject oversized files.
Does compressing to 20KB make the signature unreadable?
No. Signatures consist of simple dark strokes against white backgrounds, which compress extremely efficiently without loss of legibility.
Is my signature stored on your servers?
Never. All operations happen client-side in your browser memory.
Can I also set dimensions like 140x60 px?
Yes, enter 140 width and 60 height in the dimensions fields to resize and compress together.
