JEE Main Photo Size: 10 to 200 KB Photo, 10 to 100 KB Signature
13 Nov 2026 · 5 min read · JobCareerUpdates Blog
JEE Main photo size is 10 KB to 200 KB, and the signature is 10 KB to 100 KB. Both files are JPG or JPEG. That is the whole rule as NTA printed it in the JEE (Main) 2026 Information Bulletin, Step 2 of the application procedure.
The photo must be a recent colour passport photo on a white background, with your face covering about 80 percent of the frame and both ears visible. The bulletin gives no pixel size at all, so any site quoting an official pixel figure is inventing one.
JEE Main photo size at a glance
| File | Format | Size | What NTA asks for |
|---|---|---|---|
| Passport photograph | JPG or JPEG | 10 KB to 200 KB | Recent, colour, white background, face about 80 percent of the frame, ears visible, no mask |
| Signature | JPG or JPEG | 10 KB to 100 KB | Running handwriting in black or blue ink on plain white paper |
| Live photograph | Captured in the form | Not a file you upload | Taken by webcam or phone during registration |
The form also captures a live photograph while you fill it. Keep the uploaded photo current, so the live capture and the upload look like the same person on the same day. A photo from two years ago invites a mismatch flag at the centre, and that is a problem you do not want on exam morning.
Why half the internet disagrees with these numbers
Search for the JEE Main photo size and you will find three different answers, sometimes on the same page. One site says the photo can be 300 KB. Another says the signature must be 4 KB to 30 KB. Both are wrong for JEE Main, and both errors have the same cause: old figures and borrowed figures.
The 300 KB photo cap belonged to an earlier cycle. For 2026, NTA cut the photo ceiling from 300 KB to 200 KB and raised the signature ceiling from 50 KB to 100 KB. A guide that still prints 300 KB was written for a previous year and never updated.
The 4 KB to 30 KB signature range is NEET's, not JEE Main's. NEET and JEE Main are both run by NTA, so writers copy the NEET table into a JEE Main article and nobody notices. The bulletin for each exam is a separate document, and the numbers differ.
This is the part worth getting right, because the portal enforces the range. A photo above 200 KB will not upload, and a signature below 10 KB will not upload either. There is no appeal to a file size limit. Check the number on your file before you open the form, not after three failed uploads.
What a photo that passes looks like
Stand in front of a plain white wall in daylight. A window gives better light than a yellow room bulb, and it costs nothing. Face the camera straight on, both ears visible, no cap, no mask, no sunglasses.
Skip filters and beauty mode. They soften your face in exactly the way an ID photo must not be softened.
Do not crop your face out of a group photo. A crop from a wedding picture arrives blurred and small, and stretching it to passport size only makes the blur bigger.
Take a fresh photo with the phone you already own. It takes two minutes, and the same photo follows you to the admit card and the scorecard. Wear what you would wear to the centre, keep your hair off your forehead, and check that both ears show. Spectacles are fine if you wear them every day, but the flash must not hide your eyes.
One more check before you upload. Open the file and look at it at full size. If the face is sharp, the background is plain white, and nothing is cut off at the edges, it is ready. If you have to squint, take it again.
The signature deserves thirty seconds, not three
The JEE Main signature size is 10 KB to 100 KB, but the number is the easy half of the job. Sign on plain white paper with a black or blue pen, in the running handwriting you use every day. This is the signature that must match later, on the attendance sheet at the centre, so do not invent a stylish new one during application week. Sign once, look at it, and if it is clear and complete, photograph it straight down in good light.
The file must land between 10 KB and 100 KB. A phone photo of a signature on white paper usually lands in that range without any work. If yours comes out below 10 KB, the scan is too faint or too small, so sign slightly larger and photograph it again. If it comes out above 100 KB, compress it rather than redrawing it.
The same signature travels with you through the exam, which is why the bulletin calls for it to be clearly legible. A rushed scribble that even you cannot read is not a signature. It is a risk.
Making both files at home
You do not need a studio for this. The JEE Main preset on this site prepares your photo at 350 by 450 pixels inside the official 10 to 200 KB range, and the signature in the same sitting. Upload, check the framing, download. It all happens in your own browser, so your photos are not sent anywhere.
Two related facts are worth knowing while you are here. JEE Advanced publishes no photo size of its own. Your admit card there carries the photo and signature from your JEE Main record, so the file you prepare now is the one that follows you into Advanced as well.
And unlike NEET, JEE Main asks for no thumb impression. NEET wants the fingers and thumbs of both hands in a single image. JEE Main asks only for the photo, the signature, and the live capture.
A note on JEE Main 2027
These figures come from the JEE (Main) 2026 Information Bulletin, published 31 October 2025. That is the latest bulletin NTA has published. The 2027 bulletin had not been released when this was written, and the Session 1 exam is listed on NTA's tentative calendar for January 2027.
NTA revises details between cycles, so read the photograph and signature instructions in the 2027 bulletin before you submit. Two minutes of checking protects a year of preparation.
Sources and verification: NTA Information Bulletin JEE (Main) 2026, Step 2 of the application procedure, published 31 October 2025. Photo 10 to 200 KB and signature 10 to 100 KB, both JPG or JPEG, corroborated by Careers360, CollegeDunia, Motion and the site's own verified JEE Main preset, which prepares the photo at 350 by 450 pixels inside the 10 to 200 KB range. The bulletin prints KB ranges only and no pixel dimensions.
