JEE Main Photo and Signature Size 2026: KB, Pixels, Format

FixDoks is an independent website and is not affiliated with any government body, exam board or recruitment agency. Requirements change, so always confirm them in the latest official notification.

Per the JEE (Main) 2026 Information Bulletin, the photograph you upload must be JPG or JPEG format, between 10KB and 200KB, a recent colour photo showing at least 80% of your face including both ears against a white background, without a mask. The signature must be JPG or JPEG, between 10KB and 100KB, clearly legible. In addition to this uploaded photo, you also capture a live photograph using your camera or webcam at the time you fill the application form.

Both an upload and a live capture, in the same application

JEE Main's application step is explicit that you will have to upload your live photograph at the time of filling the application form, on top of uploading your scanned images of photograph, signature, and other documents. This two-part photo requirement, an uploaded file plus a live capture, is easy to miss if you only prepare the uploaded photo and are then surprised by a camera prompt partway through the form. Make sure your device's camera or webcam is working and permitted before you start filling the application, so you are not stuck midway through a long form.

Document	Format	File size (KB)	Dimensions	Other rules
Photograph (uploaded)	JPG/JPEG	10KB to 200KB	Passport-style	Colour, 80% face visible including ears, no mask, white background; a live photo is also captured separately
Signature	JPG/JPEG	10KB to 100KB	Not specified	Clearly legible (the bulletin gives no pixel size)
Class 10 or equivalent certificate/marksheet	PDF	50KB to 300KB	-	Must be clearly legible
Identity proof (non-Aadhaar/DigiLocker verification)	JPG/JPEG	10KB to 200KB	-	Only required if you are not verifying identity through Aadhaar or DigiLocker

Step-by-step: preparing your files

1. Take a recent colour photo against a plain white background, with both ears visible and no mask, in good daylight.
2. Sign on white paper in dark ink, in your normal running signature, and photograph it in even light.
3. Resize the photo to fit 10-200KB and the signature to fit 10-100KB, checking both are JPG/JPEG.
4. Scan your Class 10 or equivalent certificate and marksheet as a PDF, keeping the file between 50KB and 300KB.
5. If you are not verifying through Aadhaar or DigiLocker, prepare an identity proof as JPG/JPEG between 10KB and 200KB.
6. During the application, when prompted, allow camera access and follow the on-screen framing for the live photo capture.

Documents beyond the photo and signature

Depending on your category and eligibility claims, the JEE Main form may also ask for a category certificate, a PwD/PwBD certificate, or other supporting documents, each with its own size range typically similar to the 50-300KB pattern used for the Class 10 certificate. Gather every document your specific eligibility category needs before you begin the form, since discovering a missing certificate midway through a long application is one of the more common reasons candidates run out of time before a session's deadline.

Why some pages online show different KB ranges

KB ranges can change from one NTA bulletin to the next, and pages written for an earlier cycle are not always updated. The 2026 bulletin's confirmed figures (photo 10-200KB, signature 10-100KB) supersede any older figures you might see on a page written for a previous year's exam, so rely on the current cycle's bulletin rather than a page that has not been updated.

Applying to both January and April sessions

Many candidates attempt JEE Main twice in the same year, once in January and once in April, using the better of their two scores. Since the same application number and password carry across both sessions, keep your prepared photo, signature and certificate files saved well beyond your first attempt, so re-applying for the second session does not mean starting the document preparation from scratch. Re-check the bulletin for that specific session before reusing files, in case any instruction has changed between sessions.

Common mistakes on the JEE Main form

• Uploading an older photo prepared for a different exam's KB range without rechecking against the current JEE Main bulletin.
• Not testing the device's camera or webcam before starting the live photo capture step, causing delays mid-form.
• Uploading a faint or blurred signature: the bulletin asks for every image to be clearly legible.
• Uploading identity proof unnecessarily, or in the wrong format, when Aadhaar or DigiLocker verification would have skipped that requirement.

For the related CUET UG form, which shares a similar pattern but a different signature range, see the CUET UG photo and signature size guide. If your certificate PDF is over the 300KB limit, use compress PDF to 200KB to bring it down.
