Railway Recruitment Board forms such as RRB NTPC now take your photo live with the camera while you fill the form. The signature is still uploaded as a file.

Some guides still list 10–20 KB from older railway forms. If your notification gives a different range, choose Custom size and type it in.
These are the sizes published for 2026 forms. Rules can change from one notification to the next, so check the official notification before you upload.
Your photo never leaves your phone: the resizer works inside the browser, so nothing is uploaded to us.
