Why signature uploads get rejected
- The file is bigger than 100 KB. Phone photos are usually 2–5 MB, so they always need compressing.
- The file is smaller than 10 KB. This happens with small, clean images; we raise the quality first and, if needed, add standard metadata to reach the minimum.
- It's saved as the wrong format: the portal accepts JPG. iPhone HEIC photos and screenshots saved as PNG are common mistakes.
- The background isn't plain white. A tool can't fix a coloured wall or a shadow; retake it against a white wall in good light.
FAQ
What is the JEE Main signature size?
The official requirement is: JPG · 10–100 KB · white background · general preset. Source: JEE (Main) 2026 information bulletin, checked on 5 Oct 2026. Always confirm against the latest notification before you apply.
What if my signature is smaller than 10 KB?
We first raise the quality and resolution within the allowed limits. If it's still under 10 KB, we add standard metadata to the file to reach the minimum. The picture itself doesn't change, and the card tells you when this happened.
Does JEE Main also capture a live photo?
Yes. Besides the uploaded files, the application form takes a live photo with your webcam or phone camera. See the guidance on the full JEE Main page.
Is my signature uploaded anywhere when I resize it here?
No. The resizing and compression run in your browser, on your device. Your file is never uploaded to us or stored.
