Frequently asked questions
What is the signature size for RRB Railway (NTPC, Group D, ALP)?
Signature: JPG/JPEG, 140 × 60 px (minimum), 30–49 KB. Scan at 100 DPI or more. Source: RRB CEN 09/2025 (Level 1) detailed notice, last verified 19 Oct 2026.
Do I need to upload a photo for RRB Railway (NTPC, Group D, ALP)?
Photograph (live capture) is captured live with your webcam or phone camera on the official portal, so there is nothing to prepare for it here. Process change: since 2025, RRB notifications require a live image captured during the application (webcam or the phone's front camera). Do not photograph a printed or existing digital photo; it will be rejected.
My file is smaller than the minimum KB. What should I do?
Use “Make it fit”. We keep the highest JPEG quality allowed; if the image is still too small (common for simple signatures), we add harmless padding inside the file so it meets the minimum size. The picture itself does not change.
Will the portal accept a photo taken on my phone?
Usually yes, if it is sharp, well lit and on a plain light background. Crop it to the face and shoulders using the box above. Avoid filters, beauty modes and selfies at arm’s length.
Are my photo and documents uploaded to ConvertRight?
No. Everything runs inside your browser. Your files never leave your device, and nothing is stored after you close the page.
How do you know these specs are correct?
We read the official notification and link it under “Official sources” with the date we last checked (19 Oct 2026). Specs can change between years, so open the notification for your cycle if anything looks different.
