GATE Photo, Signature, Photo ID and Certificate Upload Guide
GATE application filling through GOAPS is strict about image quality. You need a passport photograph, signature, scanned valid photo ID, and where applicable SC/ST certificate, UDID or PwD certificate, dyslexic certificate and annexure PDFs. This page is built for that upload stage. Use it to prepare GATE photo size 2026 files, GATE signature size files, ID proof scans and certificate PDFs before you submit the application form.

Open toolHow to Prepare GATE Upload Files in 5 Steps
Start with a correct passport photograph
Use a recent good quality colour photograph against a white background. The face should cover 60 to 70 percent of the photo with a frontal view. Do not use a selfie, cropped group photo, low-resolution screenshot, tinted image or photo with dark glasses. GOAPS accepts JPG/JPEG photo files from 5KB to 600KB.
Resize and compress photo to 5-600KB
Open Photo Resize and use the GATE preset to create a 530x690px working image within the official 200x260 to 530x690px range. Then use Image Compress if the JPG is still heavy. Keep the face clear, not just technically small.
Prepare signature and identity proof separately
Sign inside a rectangular box on white A4 paper using black or dark blue ink. Crop only the signature area and keep the final JPG/JPEG between 3KB and 300KB, within 250x80 to 580x180px. Keep the valid photo ID scan separate because it is uploaded in a different GOAPS field.
Make certificate PDFs readable
Prepare SC/ST certificate, UDID or PwD certificate, dyslexic certificate, compensatory time annexure or scribe annexure only if applicable. Use Image to PDF, PDF Merge, and PDF Compress to keep pages readable while reducing file size.
Preview every GOAPS upload before payment
After uploading, preview the photograph, signature, photo ID and certificate PDFs. Save the confirmation page, enrolment ID, uploaded image files and payment proof because these records may be needed later for admit card, result, M.Tech admission, scholarship, PSU recruitment or document verification.
Common GATE Upload Rejection Reasons
Photo outside 5-600KB
Large phone photos fail upload, while over-compressed images may not be clearly legible.
Face not clear or wrong background
GATE expects a white background, frontal face view and 60 to 70 percent face coverage.
Disability certificate PDF not readable
A compressed PDF that hides certificate number, name, disability details or issuing authority can create verification trouble.
Wrong person's files uploaded
The bulletin warns that using someone else's photograph, signature or certificates may be treated as unfair means.
About GATE Application Documents
GATE is used for admission to postgraduate engineering and science programmes, doctoral opportunities in some institutions, scholarships and many PSU recruitment shortlists. That makes the application record important beyond exam day. A blurred signature or badly cropped photograph can create friction during scrutiny and correction.
The upload stage connects directly to identity verification. The passport photograph should match the candidate clearly, the signature should be readable, and the valid photo ID should match the details entered in GOAPS. Category, PwD, UDID, dyslexic and annexure documents are checked only where applicable, but they still need to be readable.
PrepTools keeps this preparation local. Your GATE photo, signature, ID proof, certificate PDFs and admission documents stay in the browser. You get the required JPG and PDF compression without sending files to a server.
Planning for counselling too?
GATE application files are different from later M.Tech admission or PSU verification files. Keep both sets clean.
