Most exam and recruitment portals ask for a signature image between 10KB and 20KB. A phone photo of your signature is far larger than that. Compressify resizes and compresses it to fit the limit while keeping the strokes clear and legible.

Frequently asked questions
What size should a signature image be?
Many portals want roughly 140×60 pixels and 10–20KB. Resize the longest side small, then compress to reach the KB limit.
My signature looks faint after compressing — fix?
Scan or photograph on white paper with good contrast, crop tightly, then compress. Avoid resizing it too small.
