How to Prepare a Photo and Signature for NEET and JEE

NTA's entrance examinations have the widest spread between the photograph limit and the signature limit of any Indian board, and preparing both the same way is the standard mistake.

The photograph: up to 200 KB

200 KB is generous — roughly ten times what SSC allows — so there is no need to compress hard here. A good quality JPEG straight from a decent camera will often already be in range, and over-compressing a photo that was already acceptable is a way to create a problem you did not have.

The dimensional guidance of 3.5 × 4.5 cm (about 413 × 531 px at 300 dpi) corresponds to about 413 × 531 pixels at 300 dpi.

The signature: 30 KB at the top

This is the tight one. 3–30 KB, JPEG leaves very little room, and it has a floor as well as a ceiling. The trick is that a signature is mostly white paper, which compresses extremely well — so the difficulty is usually not getting under 30 KB but staying above the minimum while the image is still legible.

Crop tightly to the signature itself. A wide crop with a lot of blank paper wastes the budget on nothing and makes the strokes smaller.

Why the minimum catches people out

This is the single most common way a second or third attempt fails. The specification is a range. A photograph squeezed down to 6 KB is rejected exactly as firmly as one at 80 KB, and the error message rarely distinguishes between the two. If you have compressed a file repeatedly trying to get it accepted, check whether you have fallen through the floor.

Name and date printed on the photograph

NEET is unusually generous on the photo at up to 200 KB but unusually tight on the signature at 3–30 KB. Some cycles also require the candidate name and photograph date printed beneath the image — check the current bulletin.

When a cycle does require it, the text has to be part of the image, not written on a printout afterwards. Add a name and date to an exam photo does it in the browser.

JEE, CUET and the other NTA exams

NTA runs JEE Main, JEE Advanced, CUET and UGC NET on similar application software, but the published figures have differed between them and between cycles, and we have not been able to verify them against a standing official page. For those, read the specification off the current Information Bulletin — the same KB search trick works in those PDFs — and then use the resizer with your own targets.

The method, in the order that works

Every one of these forms checks the same four things, and they are checked independently. A file can pass three and fail the fourth.

1. Format. JPG. Not PNG, not HEIC, not WebP, whatever your phone saved it as. Renaming the file does not convert it — portals read the bytes inside, not the extension.
2. Pixel dimensions, where the board publishes them.
3. File size, which is almost always a range rather than a ceiling.
4. Content — plain background, face filling most of the frame, a signature in running handwriting on white paper.

Do them in that order. Cropping and resizing change the file size, so if you compress first you will have to do it again. Set the dimensions, then squeeze the kilobytes, then check you are still above the minimum.

Every tool linked here runs inside your browser. Your photograph and signature are never uploaded to this site or anywhere else, which matters rather more than usual when the file is a scan of your signature.
