Railway Recruitment Board (RRB) requires a recent passport-style photograph and a scanned signature for NTPC, Group D and ALP applications. The NTPC photo must be 200 x 230 pixels in JPEG format between 30KB and 70KB, and the signature must be 140 x 60 pixels between 10KB and 40KB. Group D uses a wider 320x240 format with a 20–50KB range.
This tool resizes and compresses both files to the exact RRB spec. Everything runs in your browser — your files never leave your device.
