RRB NTPC: photo and signature guide

The official FAQ for CEN 05/2024 (NTPC) sets the photo and signature at JPEG 30-70 KB each. Newer railway recruitments may use different ranges, so match your own notice.

Official size and format

PhotographJPEG, 30-70 KB as per the CEN 05/2024 FAQ. The upload page of the form also displays the expected dimensions.

SignatureJPEG, 30-70 KB, signed on white paper in dark ink and scanned clearly.

SC/ST certificatePDF, less than 500 KB, only for candidates claiming the free travel pass.

How to prepare the files with PDF Saathi Hub

Scan or photograph your passport photo and signature in good light, without shadows.
Crop each image to its content in the Photo Editor.
In Photo / Sign KB, set 30 KB minimum and 70 KB maximum and create each JPEG.
For a caste certificate above 500 KB, use PDF Compress and then check the pages are readable.

Railway size ranges change between recruitments: ALP 01/2025 used 100-150 KB for photos while NTPC 05/2024 used 30-70 KB. Fill only the range shown on your form's upload page.

Note for this cycle

Applications for railway recruitments are now filed through the common RRB application portal linked from your zone's official website. The FAQ also reminds candidates that the exact dimensions are displayed on the upload profile documents page of the form itself.

These rules change between recruitment years and notices. The current official notice and the upload screen of your form are the final word; this guide is only a helper, not an official recruitment page.
