How it works

  1. Open the Railway (RRB NTPC, Group D) kit.
  2. Drop each file into its slot: the kit knows the size for each one.
  3. Download them one by one, or all together as a ZIP.

Why uploads get rejected

Portals check the file size window, the pixel size and the format. A file that is too small is rejected just like one that is too large. Resize Baba lands inside the full window and reads the finished file back to prove it.

A note on these sizes

Published guides disagree: photo limits of 20–50 KB and 20–100 KB both appear, and signature limits of 10–20 KB and 30–50 KB. The strictest common limits are used so the file passes either way. Use the size in your notice if it differs (Custom size).

Photo tips

  • Recent colour photo, face centred, plain light background.
  • Sign with a dark pen on white paper, then photograph or scan it flat and crop tight.
  • Save as JPG. Rename the files only if the notice asks you to.
