Don't take our word for it — turn off your Wi-Fi. Docexp keeps working. A site that runs with the network off cannot be uploading your files anywhere.
Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.
Fix a photo for an upload form →JEE Main photo and signature size
The photo and signature rules for the Joint Entrance Examination (Main) — JEE (Main), taken from the official notification — and a tool that hits them exactly, in your browser, without uploading your documents anywhere.
| Image | File size | Dimensions | Format |
|---|---|---|---|
| Photograph | 10–200 KB | recent passport size | JPG/JPEG |
| Signature | 10–100 KB | not stated | JPG/JPEG |

The part that actually gets people rejected
JEE Main and NEET share the same NTA portal and the same KB ranges, but not the same photo rule: NEET accepts colour or black & white, while the JEE Main bulletin says the photograph 'should be in colour'. Candidates applying to both often reuse one file — safe in one direction only (a colour photo works for both; a black & white one does not). And as with every NTA form, the 10 KB floor on the signature is the rejection nobody sees coming.
Our advice (not part of the official spec)
No pixel dimensions or DPI are given — 'passport size' with 80% face coverage is the whole official rule, so treat any exact pixel figure you read elsewhere as a guess. Aim mid-range (80–100 KB photo, 30–50 KB signature) so the portal's own re-encoding can't push you over an edge.
What the notification actually says
“Photograph in JPG/JPEG format (clearly legible) between 10 kb to 200 kb.”
“The recent passport size photograph should be in colour with 80% face (without mask) visible including ears against white background.”
“Signature file should be JPG/JPEG format (clearly legible) between 10 kb to 100 kb.”
