What is the RRB NTPC photo size in KB?

There is no KB figure, because there is no photo file. RRB NTPC no longer takes a photograph file. Para 14.4 of CEN 06/2025 states that candidates "are not required to upload a pre-existing photograph while applying" and that the application module captures a live photograph at the time of filling the form, through a webcam or the phone's front camera. Para 14.5 lists only two uploads: the signature and, for those requesting a free travel pass, an SC/ST certificate. Photographing an already-printed or on-screen photograph gets the application summarily rejected. The only image file you upload is the signature: JPG / JPEG, 30 to 49 KB, at least 140 x 60 px. Read from RRB CEN 06/2025 (NTPC - Graduate) detailed centralised employment notification, paras 14.4 and 14.5 dated 21 Oct 2025.

What is the RRB NTPC signature size in KB?

JPG / JPEG, 30 to 49 KB, at least 140 x 60 px. The CEN prints 30 to 49 KB, not 30 to 50 KB. RRB Group D's CEN 08/2024 does say 30 to 50 KB - the two notices differ by 1 KB, so do not carry a figure across from one to the other.

Does the RRB NTPC photo need the name and date printed on it?

There is no photograph file to print a name or date on. The photograph is captured live inside the application form. Read from RRB CEN 06/2025 (NTPC - Graduate) detailed centralised employment notification, paras 14.4 and 14.5, dated 21 Oct 2025, on 29 Jul 2026.

RRB NTPC photo and signature size

Non-Technical Popular Categories (Graduate), CEN 06/2025 · Railway Recruitment Boards (RRB)

RRB NTPC does not take a photograph file at all - the application form captures a live photograph through your webcam or phone camera, so there is no KB limit and no pixel size to hit for the photo; the only image you upload is your signature, in JPG / JPEG, 30 to 49 KB, at least 140 x 60 px. Those figures are read from RRB CEN 06/2025 (NTPC - Graduate) detailed centralised employment notification, paras 14.4 and 14.5, dated 21 Oct 2025, checked on 29 Jul 2026. The table below and the resizer on this page are generated from that one record, so the specification shown and the target the tool encodes to cannot disagree.

RRB NTPC upload specification

RRB NTPC photograph and signature upload specification: file, format, file size, dimensions and scan resolution
File	Format	File size	Dimensions	Scan resolution
Photograph	Live capture inside the form. No file, no KB limit, no pixel size.
Signature	JPG / JPEG	30 to 49 KB	at least 140 x 60 px (35 x 20 mm in the notice)	100 DPI

Other RRB NTPC photograph rules printed in the same notice
Rule	What the notice says
Background and framing	For the live capture: non-white clothing, preferably dark, to contrast with the background; camera at eye level; the whole face centred in the frame; no cap, mask or glasses/spectacles; eyes fully open, or the photo will not be captured.
Name and date printed on the photo	There is no photograph file to print a name or date on. The photograph is captured live inside the application form.
How the photograph is taken	RRB NTPC no longer takes a photograph file. Para 14.4 of CEN 06/2025 states that candidates "are not required to upload a pre-existing photograph while applying" and that the application module captures a live photograph at the time of filling the form, through a webcam or the phone's front camera. Para 14.5 lists only two uploads: the signature and, for those requesting a free travel pass, an SC/ST certificate. Photographing an already-printed or on-screen photograph gets the application summarily rejected.

What the notice adds, file by file

Signature: The CEN prints 30 to 49 KB, not 30 to 50 KB. RRB Group D's CEN 08/2024 does say 30 to 50 KB - the two notices differ by 1 KB, so do not carry a figure across from one to the other.
Signature: 140 x 60 px is the stated MINIMUM, not a fixed target; the signature must sit inside a 35 mm x 20 mm box on the form.
Signature: Black ink pen on white paper, in running handwriting - not in block, capital or disjointed letters.
Signature: Listed grounds for rejection include a non-white background, non-black ink, block or capital letters, poor resolution, an incomplete signature, a blank upload, an image that is not the signature, and a thumb impression in place of a signature.

Also in this notice

The SC/ST certificate, uploaded only by candidates requesting a free railway travel pass, is a PDF of less than 400 KB.
A colour passport photograph not older than two months is still needed as a printed photograph carried to the CBT, document verification and medical examination - it is carried, not uploaded.

RRB CEN 06/2025 (NTPC - Graduate) detailed centralised employment notification, paras 14.4 and 14.5

Document date: 21 Oct 2025
Read on: 29 Jul 2026
Status: Read from the official PDF

Read from the copy published by RRB Secunderabad; the central rrbcdg.gov.in portal did not respond when this was checked. The CEN 06/2025 PDF carries no text layer - it is a scanned document - so its pages were read as images rather than extracted as text. CEN 07/2025 (NTPC Under Graduate) prints the same rules.

Document: https://rrbsecunderabad.gov.in/wp-content/uploads/2025/10/Final-CEN-06-2025-21-10-2025-Publish.pdf

Who lands on this page

The rrbapply.gov.in upload gate rejected a file and the exact KB range is needed.
A scan is larger than the ceiling Railway Recruitment Boards (RRB) sets and has to come down without changing the pixel size.
A RRB NTPC form asks for signature and each one has a different limit.
A specification found on a coaching site needs checking against the notification it claims to quote.

How the resizer hits the target

Pick the file you are fixing: RRB NTPC accepts signature.
Choose the scan or photo from the device. It is decoded in the browser and never uploaded.
The image is drawn onto a white canvas with its aspect ratio kept, so nothing is cropped or stretched. Canvas size: at least 140 x 60 px.
A binary search over JPEG quality finds the highest quality whose encoded file still sits between 30 KB and 49 KB.
Check the pass or fail line for each rule, then download the JPEG and upload it at rrbapply.gov.in.

How this page is built

The spec and the tool are the same record: The table above and the resizer preset are generated from one entry, so the RRB NTPC target shown is the target the tool encodes to.
Every row is dated: Each figure carries the document it came from (RRB CEN 06/2025 (NTPC - Graduate) detailed centralised employment notification, paras 14.4 and 14.5) and the date that document was read (29 Jul 2026), so a row that goes out of date reads as a dated fact rather than a wrong one.
The file never leaves the device: Decoding, resizing and JPEG encoding all happen in the browser through a canvas; nothing is uploaded to a server.
The size is searched, not guessed: A binary search over JPEG quality finds the highest quality whose encoded size still sits inside the range, then reports the size, the quality and the number of steps it took.
