Resize Your Photo & Signature for RRB Railway Forms
RRB railway recruitment (NTPC, Group D, ALP) forms require a recent colour photo and a signature within set size limits. Here are the typical specs and the free tools to hit them, all in your browser.
The requirement
- Photo file size
- 15 KB – 40 KB
- Photo dimensions
- ≈ 35 mm × 45 mm, colour, plain background
- Signature file size
- 10 KB – 40 KB
- Format
- JPG / JPEG
These are typical published values and can change from year to year and from one portal to another. Always confirm the exact requirement in the official notification or upload portal before you submit — the official source takes precedence over anything here.
