JEE Main upload sizes (2026 form)
| Upload | Size | File size | Format |
|---|---|---|---|
| Photograph | 3.5 cm × 4.5 cm | 10–200 KB | JPG / JPEG |
| Signature | 3.5 cm × 1.5 cm | 10–100 KB | JPG / JPEG |
For 2026 the photo limit came down from 300 KB to 200 KB and the signature limit went up from 50 KB to 100 KB, so files prepared for an earlier year may no longer fit. The tool converts the centimetre sizes to pixels at 200 DPI: 276 × 354 and 276 × 118.
These figures were last checked in November 2026. Requirements can change with each notification, so confirm them in the current official notice on jeemain.nta.nic.in before you upload. All four boxes in the tool can be edited if your form asks for something different.
Photo rules
Use a recent colour passport-size photo on a plain white background with about 80% of the face visible, including the ears. Sign on a white sheet with a blue or black pen.
Why uploads get rejected
- The file is a few KB over or under the allowed range.
- The file is PNG, HEIC or PDF when the form accepts only JPG.
- The face is too small, off-centre or in shadow, or the background is not plain and light.
- The signature is in capital letters, faint, or signed by someone else.
- A screenshot or a photo forwarded through a chat app was used, which lowers quality.
Questions and answers
Can I fix a wrong photo after submitting?
NTA usually opens a correction window in which images can be replaced. Watch the official site for the dates.
Does JEE Advanced use the same sizes?
No. JEE Advanced has its own portal and instructions. Use the custom boxes in the tool with the figures from that form.
