Why this size

What RRB asks for

Railway Recruitment Boards now take your photo live during the application, so you upload only your signature: a JPG between 30 and 49 KB, at least 140 x 60 pixels. That range is unusual. Most resizers aim for 10 to 20 KB, which RRB rejects as too small. This page lands the file inside 30 to 49 KB.

File	Rule
Signature	At least 140 x 60 px, 30 to 49 KB, JPG

Checked

How we checked this page

Checked by the SizePort team on 3 October 2026.

We compare every size and rule on this page with the official sources below, and test the tool with sample photos before it goes live. Rules and platforms change, so if something here is out of date, tell us and we will correct it.

How the tool works

The kit sets each file to the exact pixel size the form gives, then searches for the JPG quality that lands it inside the KB range. If a small file is still under the minimum, it adds an empty comment block inside the JPG, which raises the size without changing the picture. It also writes the DPI the form asks for. Everything happens in your browser; your images are never uploaded.
