The National Testing Agency (NTA) runs NEET (UG) and JEE (Main). Both forms ask for a scanned photo and signature, capture a live photo, and ask for some documents as PDFs. NTA gives the limits in KB only, with no fixed pixel size.
Quick summary (2026 information bulletins)
- Photo: JPG/JPEG, 10 KB to 200 KB. Recent passport-size photo, 80% of the image should be your face (without mask), ears visible, white background.
- JEE Main: the photo must be in colour.
- NEET (UG): colour or black and white is allowed, and the 2026 bulletin asked for a photo taken after 1 January of that year.
- Signature: JPG/JPEG, 10 KB to 100 KB, clearly legible.
- Live photo: captured during the application.
- Class 10 certificate / marksheet and most other documents: PDF, 50 KB to 300 KB.
- NEET only: left and right hand finger and thumb impressions as JPG/JPEG (the 2026 bulletin lists 10 KB to 200 KB).
NTA has changed these limits between years (the signature limit used to be much smaller), so check the bulletin for your session.
Step 1: The photo
- Take a photo against a plain white wall, in daylight, without a mask or cap.
- In the Passport Size Photo Maker, choose the India 35 × 45 mm size and pull the frame in so your face fills most of the photo, with both ears showing.
- Download the single photo and compress it with Compress Image to 100 KB. A result between 40 and 100 KB is safely inside the 10–200 KB window.
Use the same photo everywhere. The NEET bulletin advises keeping several identical prints (passport size and postcard size) for the exam and counselling.
Step 2: The signature
Sign on white paper, photograph it straight from above, crop it, then compress with the Image Compressor to a target of about 40 KB. If it comes out under 10 KB, make the image bigger (for example 600 px wide) and compress again.
Step 3: Document PDFs (50–300 KB)
- Photograph your Class 10 certificate or marksheet flat, in good light.
- Turn the photo into a PDF with JPG to PDF.
- If it is over 300 KB, shrink it with the PDF Compressor (Strong mode). If it is under 50 KB, rebuild it from a larger, clearer photo.
Common mistakes
- Face too small in the photo, or ears hidden
- Black and white photo for JEE Main, where colour is required
- Signature file below 10 KB
- PDF under 50 KB or over 300 KB
NTA publishes a new information bulletin for every session. Always check the bulletin on neet.nta.nic.in or jeemain.nta.nic.in before you upload. ToolSandook is not connected to NTA.
