Compress photo for JEE Main 2026

JEE (Main) 2026 upload size: the official spec

The JEE (Main) 2026 — Information Bulletin (NTA) asks for two image files, and states each one as a band rather than a single cap. In the bulletin’s own words: “Photograph in JPG/JPEG format (clearly legible) between 10 kb to 200 kb.” and “Signature file should be JPG/JPEG format (clearly legible) between 10 kb to 100 kb.” Neither instruction mentions pixel dimensions, so the portal is judging the file on its size and on what the picture shows — not on its exact width and height. For any other form that states its limit only in kilobytes, resize an image to a KB size you choose.

Colour is not optional

This is the detail that separates JEE (Main) from its sister exam. The NEET (UG) bulletin, from the same agency, accepts a photograph in colour or in black and white. The JEE (Main) bulletin does not: the photograph must be in colour. A grey-scale scan of an old print, or a photo run through a “document” filter on a scanning app, fails this rule however well it is sized.

Scanning apps are the usual culprit. Many default to a black-and-white or “magic colour” mode designed for text pages, and that mode quietly drains a portrait of its colour. If you photographed a printed photo with one of them, switch the app to its plain photo mode and take the picture again.

If you are applying to both exams, the simple answer is one colour photograph used for both. The NEET UG page covers its three uploads, including the finger-and-thumb impressions file JEE (Main) does not ask for.

Framing the photograph

After colour, the bulletin’s requirements are about how much of you is in the frame: 80% of the face visible, ears included, no mask, against a white background. In practice that is a head-and-shoulders portrait, shot straight on, with nothing behind you but a white wall.

• Tie long hair back or tuck it behind your ears — the ears are meant to be visible.
• Take the photo at arm’s length or closer. A photo from across the room, cropped hard later, leaves the face soft and small.
• Stand a little away from the wall so your shadow does not fall behind your head.
• If the shape is wrong after all that, crop it to a portrait before compressing. The compressor keeps the proportions you give it.

A room without a white wall is a common problem. The passport photo maker replaces the background with white and crops to head and shoulders; size the result here afterwards.

The signature file

Sign on plain white paper with a dark pen, photograph or scan it, and crop close to the signature. A signature image is mostly blank paper, so it compresses very easily — the risk is overshooting. A tightly cropped signature saved at low quality can fall under the floor of 10–100 KB, and a file under the floor is refused just as a file over the ceiling is. The tool above reports both bounds, so you can see which side of the band the result sits on before you download it.

The live photograph

The bulletin adds a second requirement during the application: a live photograph is also captured during the application. It is in addition to the uploaded JPG, not instead of it. Apply from a place with even light and a plain background, without a cap or mask, and the live capture will be as straightforward as the upload.

A last look before you upload

Open the finished photograph at full size before it goes anywhere. Phones store the way they were held as a hidden orientation tag, and some upload forms ignore that tag — a portrait that looks upright in your gallery can arrive on the form lying on its side. If the result looks sideways anywhere, rotate the original before compressing it again. Check, too, that the face is sharp at full size and not only in the thumbnail; a photo that was blurred before compression stays blurred after it, and no setting in the tool can add detail back. Finally, give the two files names you can tell apart, such as your name followed by “photo” and “signature”, so the wrong one does not land in the wrong field.

Why JEE (Main) photos get questioned

Black-and-white or washed-out photos, for the reason above.

Ears hidden by hair, a hood or headphones.

A background that is not white — a bedroom, a curtain, a coloured wall.

The wrong file type. iPhones save HEIC, many apps export PNG. Both files must be JPG/JPEG, and the tool always writes JPEG.
