Railway RRB signature and photo resizer (NTPC, ALP, Group D)
Railway forms capture your photo live, but the signature still has to be uploaded as a JPG of 30–49 KB. That's an awkward size for a small image; this preset hits it exactly.
Private by design. Your photos never leave your device.

Certificates to upload too?

Tips to get it accepted first time
- RRB rejects signatures in capital or block letters. Sign the way you normally do, in black ink, inside a box about 3.5 × 2 cm.
- A 140 × 60 signature is naturally only a few KB. To reach the 30 KB minimum the resizer saves at top quality and adds harmless padding inside the file; the picture itself doesn't change.
- For the live photo, sit facing a window, against a plain wall, without a cap or glasses.
- Your photo, signature and thumb impression are exactly what someone needs to impersonate you on a form. This resizer never uploads them: everything runs on your device.

What is the Railway RRB photo size?
276 × 354 px (3.5 × 4.5 cm), 30–70 KB, JPG. White background, face fills about 50–60% of the frame. RRB CEN 06/2025 and 07/2025 capture your photo live in the portal. Use this only where a railway form still asks for an uploaded photo. These are the specifications as of October 2026; always confirm against your notification on rrbapply.gov.in.
Is my photo uploaded anywhere?
No. The resizer runs entirely inside your browser using your device's own processor. Your photo is never sent to a server, never stored and never seen by us. Once the page has loaded you can switch on airplane mode and it keeps working.
My form needs at least 20 KB but the file comes out smaller. What do I do?
Nothing: the resizer handles it. Small images such as a 140 × 60 signature are naturally only a few KB. When a form sets a minimum, the resizer saves at top quality and, if that's still too small, pads the JPG with harmless filler data inside the file. The picture is unchanged and the file meets the limit.
Does 50 KB mean 50,000 or 51,200 bytes?
Portals don't agree, so the resizer aims inside both readings: under the maximum counted in thousands, and over the minimum counted in 1,024s. A file shown as 20–50 KB here passes either way.
