Image Resizer PCRRB NTPC signature 30 KB and photo size rules
For the RRB NTPC application the signature has a hard ceiling of 30 KB and is usually expected at around 140×60 pixels. The photo sits in a wider 5–200 KB range. Both are uploaded as JPG.
The signature is the one people trip on, because 30 KB is small and the pixel box is narrow. The good news: a clean black-ink signature on white paper compresses easily to 30 KB while staying perfectly readable. If your region's RRB notification lists a slightly different limit, follow your portal's exact requirement.
- Signature: max 30 KB, about 140×60 px, JPG.
- Photo: 5–200 KB, JPG — aim high in the range for a sharp face.
- Sign with a dark pen on white paper and crop tightly before resizing.
How to fit the signature under 30 KB and keep it legible
Start with a tight crop. If your scan has a wide white margin around the signature, trim it so the strokes fill the frame — that alone removes a lot of wasted size. Then set the box to 140×60 px and type 30 in the KB field.
The app runs a quality search to land at or just under 30 KB, and if the file is still heavy it nudges the dimensions down. At 30 KB a signature stays clearly readable; you only risk softening if you push far below the limit, so there's no reason to go lower than the portal asks.
Resize the RRB NTPC photo without losing sharpness
The photo range goes up to 200 KB, so you have room to keep it crisp. Target somewhere near 180–200 KB rather than the 5 KB floor — the higher you sit in the allowed band, the clearer your face reads to the examiner.
Everything happens on your Windows PC. Unlike the upload sites that rank for this search, your signature and photo never leave your computer — no account, no watermark, and you can resize both in one go.
