JEE Main 2027 signature size in pixels, background, live photo
The JEE (Main) 2027 Information Bulletin fixes no pixel size. The photo is JPG/JPEG 10-200KB on a white background with 80% of the face and ears visible, the signature JPG/JPEG 10-100KB, and a live photo is also captured. Session 1 corrections run 27-29 November 2026.

The JEE Main 2027 bulletin gives no pixel size for the signature or the photo, only file size: signature JPG/JPEG 10-100KB and photo JPG/JPEG 10-200KB. So a "10-20KB signature in pixels" rule does not exist for this exam, and any pixel figure you see elsewhere is not from NTA.

Source: JEE (Main) 2027 Information Bulletin, NTA (2026). The bulletin calls the photo "passport size" but never states centimetres or pixels, so there is no official 3.5 x 4.5cm figure to match for the upload.
Bring a phone photo or scanned signature into these ranges with the JEE Main photo and signature resizer. Dates and the Session 1 correction window are in the JEE Main 2027 registration and correction guide.

Signature size in pixels: what to do when no pixels are given
The portal checks file size and format, so pixels are your choice. Sign on plain white paper with a dark pen, crop close to the ink, and keep it wide rather than tall. If the file is above 100KB, reduce the quality first. Shrinking pixels too far makes the strokes blocky, and the bulletin wants the signature clearly legible.
Do not push a signature down to 10-20KB just because another exam asks for it. The bulletin range starts at 10KB, so a file below that is outside the rule.
Does the photo need a name and date on it?
The bulletin does not ask for a name or date on the photograph. It asks for a recent colour photo against a white background with 80% of the face visible, ears included, and no mask. A date strip printed on the photo is not part of those rules.
Blue or other background, and a wrong background already uploaded
The bulletin says white, for the uploaded photo and for the live photo. It does not say a blue background is accepted, so do not use one. If your background is cluttered, fix it with the white background photo tool before you resize.
If a wrong photo is already submitted, the only route is the one-time correction window, 27 to 29 November 2026 for Session 1. The bulletin says the list of editable fields is published when the window opens, so check that your photo is on it. After the window closes, NTA does not entertain corrections sent by post, fax, WhatsApp, email or by hand.
Live photo not uploading: the fix list
- Allow the camera. Switch it on or connect a webcam before you open the live photo step.
- Scan the QR code. If your device has no webcam, the form shows a QR code to open on a phone or tablet.
- Fix the light. Sit against a white wall with light on your face and both ears visible.
- Retake without a mask. A mask or cap breaks the 80% face rule.
The bulletin does not publish a separate size limit for the live photo.
Aadhaar photo mismatch
NTA reserves the right to verify your details and photographs, and it advises candidates to update their Aadhaar with a recent photo, name, date of birth, gender and address. The bulletin does not describe a mismatch notice procedure. If your Aadhaar photo is very old, update it through UIDAI and keep the uploaded photo recent.
Checklist before you submit
- Photo and signature are JPG or JPEG, not PNG renamed to .jpg.
- Photo is 10-200KB and signature 10-100KB.
- Photo is your own, recent, in colour, on white.
- Class 10 certificate is a PDF of 50-300KB; compress a large one with Compress PDF to 100KB only if it stays readable.
- Keep two extra copies of the same photo for the admit card and attendance sheet on exam day.
Uploading someone else's photograph or signature is treated as unfair means under the bulletin. Use your own, and use the all-exams size guide only for comparing other forms.

Frequently asked questions
What is the JEE Main 2027 signature size in pixels?
The bulletin gives no pixel size. It fixes only the format, JPG/JPEG, and the file size, 10-100KB. Keep the signature clear and cropped, and check the KB size before upload.
Is a 10-20KB signature accepted for JEE Main?
The range is 10-100KB, so a signature of 10KB or more is within the rule. A file under 10KB falls outside it.
What is the exact passport size photo dimension for JEE Main?
The bulletin asks for a recent scanned passport size photo in colour but gives no centimetres or pixels, only 10-200KB and JPG/JPEG. The two extra passport size photos for exam day should be the same as the one you uploaded.
Should the JEE Main photo have name and date on it?
The 2027 bulletin does not ask for a name or date on the photograph. It asks for a recent colour photo on a white background with 80% of the face and both ears visible.
Can I upload a photo with a blue background?
The bulletin states a white background, so use white. It does not list blue as accepted.
I submitted the wrong photo. Can I change it?
Only in the one-time correction window, 27 to 29 November 2026 for Session 1, and only if the photo field is enabled. NTA publishes the editable fields when the window opens.
What if the live photo will not upload?
Allow camera access, or scan the QR code on a phone if your device has no webcam. Use a white background, good light, both ears visible and no mask.
