Resize your RRB NTPC images
Pick a preset for each item for RRB NTPC. Runs in your browser — nothing is uploaded.
Minimum 30KB — we'll warn you if it comes out smaller.
Step by step
- 1Sign in black ink on white paper, in running handwriting.
- 2Photograph it in good light without shadows.
- 3Use the 30–49KB preset above — note the higher minimum than SSC or IBPS.
- 4Upload in the RRB application.
Why 30KB minimum?
RRB's signature range is higher than the 10–20KB used by SSC and IBPS. Re-using a 15KB SSC signature will be rejected — resize it again with this preset, or keep more pixels.
Common reasons uploads get rejected
- Re-using a 10–20KB signature from another exam.
- Following old guides that ask for a 20–50KB photo upload — the current cycle captures it live.
- Block letters instead of running handwriting.
