GATE 2027 Photograph and Signature Guidelines have been officially released by IIT Madras for candidates applying through the GATE Online Application Processing System (GOAPS). Applicants must upload their recent passport-size photograph and handwritten signature in the prescribed format, dimensions, resolution, and file size. The uploaded images will appear on the GATE 2027 Admit Card and Scorecard, making it essential to follow all official specifications carefully. Applications with incorrect or unclear photographs and signatures may be rejected during scrutiny, and the application fee will not be refunded.
Candidates must upload a recent, high-quality passport-size colour photograph while filling out the GATE 2027 application form. The uploaded image will appear on the GATE 2027 Admit Card and Scorecard, so it should strictly follow the specifications prescribed by IIT Madras.

Candidates must ensure that their uploaded photograph satisfies all of the following requirements:

The background must be plain white and should not contain any objects or other persons.
The photograph should display a full frontal face view, with the candidate looking directly into the camera.

Caps, hats, sunglasses, coloured glasses, masks, or other objects covering the face are not permitted.
Candidates who normally wear spectacles may keep them on, but there should be no glare on the glasses. If glare cannot be avoided, spectacles should be removed.
Head coverings are allowed only for religious reasons, provided the complete facial features—from the bottom of the chin to the top of the forehead and both sides of the face—are clearly visible.
Photographs that do not meet these specifications may result in rejection of the GATE 2027 application, and the application fee will not be refunded.
While capturing or editing the photograph, candidates should follow these additional instructions:
The face should cover the A2, A3, B2, B3, C2, and C3 grid areas.
Use a plain white background.
Keep the eyes and face directed straight towards the camera.
Ensure the image is sharp, properly cropped, and well-lit before uploading.
The following types of photographs are not accepted for GATE 2027:

Incorrect photograph dimensions
Shadow on the face
Non-white or cluttered background
Face partially covered
Presence of another person in the photograph
Glare on spectacles
Wearing sunglasses
Wearing a cap without religious reason
Wearing a face mask
Looking away from the camera
Blurred or low-quality photograph
Candidates must upload a clear image of their handwritten signature while completing the GATE 2027 application form. The signature uploaded during registration will be verified during the examination process. Therefore, it must strictly follow the specifications prescribed by IIT Madras.

Candidates should carefully follow the instructions below while uploading their signature:

Upload a handwritten signature in JPG/JPEG format.
The image should have an aspect ratio (Height : Width) of 1 : R, where R ranges between 2.75 and 3.75.
After cropping, the signature should occupy 70–80% of the image area.
The signature must be made only in black or dark blue ink.
The uploaded file size should be between 3 KB and 300 KB.
The image resolution must be at least 250 × 80 pixels and should not exceed 580 × 180 pixels.
The signature must be signed only by the candidate and not by any other person.
Ensure that the signature is clear, properly cropped, and fully visible before uploading.
The signature uploaded in the application form must match the signature made during the GATE 2027 examination. Any mismatch may lead to disqualification of the candidate.
The following signatures will be rejected:

Signature on a dark background
Signature written in ALL CAPITAL letters
Digital or scanned digital signature
Signature in colours other than black or dark blue
Very small signature
Initials instead of full signature
Blurred signature

Before submitting your GATE 2027 application, ensure that:
The photograph is taken within the last three months.
Both files are in JPG/JPEG format.
File sizes are within the prescribed limits.
Images are properly cropped.
The face is fully visible with a white background.
The signature is handwritten and clearly readable.
Both images comply with the official specifications to avoid application rejection.
IIT Madras will scrutinize every uploaded document during the application verification process. Applications containing unclear photographs, incorrect signatures, or images that do not meet the prescribed specifications may be marked defective or rejected. Since the same photograph appears on the GATE 2027 Admit Card and Scorecard, candidates should upload clear and accurate images during registration.
