Photo Format for Online Forms (SSC, Bank, Railway, Defence)

✅ Photo & Signature Dimensions for SSC, Banking, Railway & Defence Exams (Updated 2025-2026)

Uploading correctly formatted documents is the most crucial step when applying for Indian government jobs online. Almost every major exam portal uses automated scripts to check the exact dimensions and file sizes of your photos, signatures, and thumb impressions. If they do not perfectly match the specifications, your application will be immediately rejected.

General Guidelines Applicable to All Exams

File Format: All exams require JPG or JPEG format exclusively.
Background: White or light-coloured background is mandatory. It must be plain, with no patterns or shadows. If your photo has a dark or colored background, you must change it to white.
Photograph Style: Must be recent (not older than 3 to 6 months), passport-style, with your face covering 70-80% of the frame. Maintain a neutral expression. No caps, hats, tinted glasses, or sunglasses are allowed (clear prescription glasses are usually fine unless applying for Defence).
Signature: Use black or dark blue ink on plain white paper. You must write in a running hand—capital or block letters will cause instant rejection.
Left Thumb Impression: If required, press your left thumb firmly on white paper using black or blue ink. Ensure the ridges are clear and not smudged.

1. SSC Exams (CGL, CHSL, MTS, GD Constable, Stenographer, etc.)

The Staff Selection Commission has largely unified its document requirements across all major exams. However, always verify with your specific exam notification on ssc.gov.in.

Photograph	3.5 cm × 4.5 cm (35×45 mm)	320 × 240 or similar	15 – 50 KB	No

5. Agniveer (Agnipath Scheme – Army, Air Force, Navy) – 2026 Cycle

Applying for the Defence forces under the Agnipath scheme comes with a very specific, mandatory requirement: The Black Slate Photo.

Air Force & Navy: The photo must show you holding a black slate horizontally in front of your chest.
Indian Army: While not always strictly mandatory for online upload depending on the rally, using the slate photo ensures uniformity and safety during physical checks.
Slate Text: You must write your Full Name and the Date of Photograph on the slate using white chalk in CAPITAL LETTERS.
Rally Requirement: Army candidates must carry 20 unattested physical prints of this exact same photo to the physical rally.
Thumb Impression: Mandatory for upload in almost all Agniveer cases.

Photograph (Slate)	3.5 cm × 4.5 cm	200×230 or 413×531	10 – 50 KB	No
Signature	3.5 cm × 1.5 cm	140×60 or 413×177	10 – 50 KB	-
Left Thumb Impression	3 cm × 3 cm	240×240	10 – 50 KB	Yes

Frequently Asked Questions

Common questions about resizing your documents for online government forms.

What is the standard photo size for most online government forms?

The most common standard across SSC, Banking, and Railways is a passport-size photo (3.5 cm x 4.5 cm). Digitally, this is around 200x230 pixels, with the file size strictly compressed between 20 KB and 50 KB in JPG format.

What is the Agniveer "Slate Photo" rule?

Candidates applying for Agniveer (especially Air Force and Navy) must hold a black slate in front of their chest. The slate must display the candidate's Full Name and the Date of Photograph written clearly in white chalk using CAPITAL LETTERS.

How can I digitally add a name, date, or slate to my photo?

You can use our free tool above. Upload a standard photo of yourself, and activate either the "Standard Name & Date" toggle (for SSC/RRB) or the "Agniveer Black Slate" toggle. Enter your details, and the tool will dynamically overlay the information onto your image.

What are the general rules for signature uploads?

Signatures must be scanned and heavily compressed, usually between 10 KB and 20 KB. You must sign using black or blue ink on plain white paper. Crucially, signatures written in uppercase block letters are universally rejected.

Are spectacles allowed in online form photographs?

For SSC, Banking, and Railways, normal prescription glasses are allowed as long as there is no flash glare on the lenses. However, for Defence exams (NDA, Agniveer, AFCAT), spectacles of any kind are strictly prohibited. Sunglasses and tinted glasses are banned across all exams.

How do I compress my high-quality mobile photo to exactly 50KB?

Upload your high-resolution image (up to 3 MB) into our resizing tool. It will automatically crop the image to the required dimensions (e.g., 200x230 px) and algorithmically compress the file down to the 20-50 KB range without losing essential clarity.
