What is the RRB Group D photo size in KB?

JPEG, 50 to 100 KB, 320 x 240 px. Colour passport photograph on a white or light-coloured background, in non-white dress, preferably dark. No cap or hat, no sunglasses or dark glasses. The face must occupy at least 50% of the photograph, with a full-face view looking straight at the camera, forehead, eyes, cheeks, nose, neck, chin and both shoulders clearly visible, and no hair, cloth or shadow across the main features. The CEN states the photograph must be taken in a professional studio and that mobile or self-composed portraits may result in rejection. Read from RRB CEN 08/2024 (Level-1) detailed centralised employment notification, para 16.0(c), dated 22 Jan 2025, on 29 Jul 2026.

How do I reduce a photo to under 100 KB for RRB Group D?

Keep the pixel size the notice asks for and lower the JPEG quality until the file lands between 50 KB and 100 KB - that is the range Railway Recruitment Boards (RRB) accepts. The resizer on this page does exactly that: it draws your photo onto a 320 x 240 px canvas without cropping it, then binary-searches JPEG quality for the highest setting whose file still fits the range. Re-scanning at a lower DPI or fewer colours is the other route the notice itself suggests.

What is the RRB Group D signature size in KB?

JPEG, 30 to 50 KB, 140 x 60 px. White paper, black ink pen only, running letters, NOT in block or capital letters.

Does the RRB Group D photo have to be recent?

Yes. CEN 08/2024 states the colour photograph must not be older than two months with respect to the last date for submission of the online application, and that it must be a latest photograph taken in a professional studio. Read from RRB CEN 08/2024 (Level-1) detailed centralised employment notification, para 16.0(c), dated 22 Jan 2025, on 29 Jul 2026.

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

The opposite of required - it is forbidden. CEN 08/2024 states in as many words that the photograph "should be free from signature/name/dates or any other marks". A name or date written on the photograph is a ground for rejection here, so do not carry that habit over from forms that ask for it. Read from RRB CEN 08/2024 (Level-1) detailed centralised employment notification, para 16.0(c), dated 22 Jan 2025, on 29 Jul 2026.

RRB CEN 08/2024 (Level-1) detailed centralised employment notification, para 16.0(c), dated 22 Jan 2025. It was opened and read on 29 Jul 2026. The figures were read from that document itself.

RRB Group D photo and signature size

Various posts in Level 1 of the 7th CPC Pay Matrix, CEN 08/2024 · Railway Recruitment Boards (RRB)

RRB Group D needs a photograph in JPEG, 50 to 100 KB, 320 x 240 px, and a signature in JPEG, 30 to 50 KB, 140 x 60 px. Those figures are read from RRB CEN 08/2024 (Level-1) detailed centralised employment notification, para 16.0(c), dated 22 Jan 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.

Other RRB Group D photograph rules printed in the same notice
Rule	What the notice says
Background and framing	Colour passport photograph on a white or light-coloured background, in non-white dress, preferably dark. No cap or hat, no sunglasses or dark glasses. The face must occupy at least 50% of the photograph, with a full-face view looking straight at the camera, forehead, eyes, cheeks, nose, neck, chin and both shoulders clearly visible, and no hair, cloth or shadow across the main features. The CEN states the photograph must be taken in a professional studio and that mobile or self-composed portraits may result in rejection.
Name and date printed on the photo	The opposite of required - it is forbidden. CEN 08/2024 states in as many words that the photograph "should be free from signature/name/dates or any other marks". A name or date written on the photograph is a ground for rejection here, so do not carry that habit over from forms that ask for it.
How recent the photograph must be	Yes. CEN 08/2024 states the colour photograph must not be older than two months with respect to the last date for submission of the online application, and that it must be a latest photograph taken in a professional studio.
How the photograph is taken	RRB Group D still takes an uploaded photograph file. This is the opposite of RRB NTPC, whose current CEN captures the photograph live in the form and takes no photo file at all - do not carry the rules across between the two.

What the notice adds, file by file

Photograph: The CEN prints both figures side by side: 35 mm x 45 mm, or 320 x 240 pixels. Those two are not the same shape - 35 x 45 mm is portrait, 320 x 240 px is landscape. The resizer uses the pixel figure, since that is what the upload gate measures.
Photograph: Minimum 100 DPI scan resolution.
Photograph: Must not be older than two months with respect to the last date for submission, and must be free from signature, name, dates or any other marks.
Photograph: Candidates are asked to keep at least 12 copies of the same photograph that was uploaded, for document verification and the medical test.
Signature: White paper, black ink pen only, running letters, NOT in block or capital letters.
Signature: Minimum 100 DPI; the complete signature must sit inside its box in the form.
Signature: Group D's range is 30 to 50 KB. RRB NTPC's current CEN prints 30 to 49 KB - the two differ by 1 KB.

Also in this notice

A scribe's passport photograph, where a scribe is used, carries the same 50 to 100 KB JPEG rule.
The SC/ST certificate, uploaded only by candidates requesting a free railway travel pass, is a PDF of up to 500 KB.

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 Group D form asks for photograph, 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 Group D accepts photograph, 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: 320 x 240 px.
A binary search over JPEG quality finds the highest quality whose encoded file still sits between 50 KB and 100 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 Group D target shown is the target the tool encodes to.
Every row is dated: Each figure carries the document it came from (RRB CEN 08/2024 (Level-1) detailed centralised employment notification, para 16.0(c)) 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.
