If you are applying for the latest RRB Recruitment and your signature keeps getting rejected, you are likely facing a common “File Size” issue. Most online tools are built to compress images, but for Railway exams, you often need a JPG size increase to hit the mandatory minimum 30KB limit.

Our RRB signature compressor is unique because it doesn’t just shrink your file; it “Force-Fixes” it to stay strictly within the 30KB to 50KB range while maintaining the exact 140 x 60 pixel dimensions required by the Railway Recruitment Board.
