What is the required signature size for RRB Railways?

Signatures for RRB Railways must be strictly between 30 KB and 70 KB, with dimensions of approx. 300x150 pixels signed clearly in blue or black ink.

Why does the RRB Railways portal say "File size is too small"?

The RRB Railways portal upload validator filters out images below 30 KB. If your smartphone compressed the photo to below this limit, our tool adds harmless metadata padding to elevate it safely to 40 KB without blurring your face.

Are candidate photos uploaded to your servers?

Never. All image processing takes place 100% inside your web browser. Zero bytes are uploaded to our servers, preserving your confidential identity data.
