RRB Signature Resizer

RRB Signature Resizer – Fix 140×60 px & 30KB–50KB

When applying for RRB Group D, ALP, NTPC, or JE recruitment, the online form strictly requires your scanned signature to be exactly 140×60 pixels with a file size between 30KB and 50KB. Most ordinary image tools either compress too much (below 30KB) or leave the file too large (above 50KB), causing your application to be rejected.

This tool force-fixes your signature to land precisely within the 30–50KB range while maintaining the exact 140×60 pixel dimensions. It uses an intelligent algorithm that adjusts quality and upscaling factor in real time to hit the target — all inside your browser, with no upload to any server.
