How it works

Sign correctly

Use black ink on plain white paper, write in running/cursive handwriting, and avoid block capitals or disconnected letters.

Prepare the JPG

Select a JPG/JPEG file and let the browser create an output at least 140 x 60 pixels while checking the 30-49 KB range.

Capture the photo separately

Use the application camera for the live photo. Do not upload an old passport photo to a file-upload field that the CEN does not provide.

Frequently asked questions

What signature values are required for RRB NTPC CEN 06/2026 and CEN 07/2026?

Both current notices specify a scanned JPG/JPEG signature between 30 KB and 49 KB with minimum 140 x 60 pixel dimensions. Use black ink, running handwriting, plain white paper, and at least 100 DPI, then compare the live application before submission.

Does RRB NTPC Graduate require a photo upload?

The notice requires a live photo captured inside the application. It says not to use a pre-existing photograph. Follow the camera instructions shown by the application form.

Why does my RRB NTPC signature get rejected?

Common causes are PNG instead of JPG/JPEG, a file outside the active CEN range, dimensions below the active minimum, low scan quality, a non-white background, or block/disjointed handwriting.

Does an RRB NTPC application require a photo upload?

The photo workflow is CEN-specific. Some notices use live photo capture rather than a pre-existing file upload. Follow the camera and upload instructions shown by the active official portal.

Do not confuse the two upload steps

RRB NTPC Graduate uses two different processes. The photograph is captured live in the application. The signature is the scanned JPG/JPEG file that must meet the notice limits. A tool that only resizes an old photo would solve the wrong problem for this CEN.

Exact error-intent searches this page addresses

This guide uses plain-language help for searches such as “RRB NTPC signature rejected”, “RRBApply signature size in KB”, “RRB NTPC signature 140x60”, and “signature must be between 30 KB and 49 KB”. The values come from the current 2026 CEN notices; the live application remains the final authority.

Official references

Compare the CEN 06/2026 notification and CEN 07/2026 notification, then use the RRB application portal for the active form. Requirements can change if RRB publishes a correction or replacement notice, so compare the live application before submitting.
