Why Use Our 20KB Photo & Signature Compressor?
Government Exam Portals
Websites like SSC (Staff Selection Commission), UPSC, State PSC, and Railway recruitment mandate that candidate passport photos and signatures must be below 20KB. This tool produces files guaranteed to pass their strict upload validation.
Compress Signature to 20KB
Our binary search algorithm maintains sharp signature strokes, dark ink lines, and readable handwriting without blotches or pixelation at exact 20KB limits.
