Detailed NTA Rules for Candidate Photograph
The passport photograph must be recent (taken within the last 6 months). The candidate's face must occupy at least 80% of the image frame with a clear, neutral facial expression and without a face mask.
The background must be plain white. Both ears must be clearly visible. Polaroid photos, self-attested photos, or photos taken with hats or caps are strictly non-compliant and cause application rejection.
Spectacles are permitted ONLY if routinely worn by the candidate, provided there is no glare, flash reflection, or tinted lens obscuring the eyes.
- 80% face coverage with visible ears against a pure white background.
- No face masks, caps, dark sunglasses, or heavy shadows across the face.
- No polaroid prints or physical photographs snapped with a phone camera from an album.
- Clear JPG/JPEG format strictly between 10 KB and 200 KB.
- Both color and black-and-white photos with 80% face visible are accepted, though color is recommended.
Live Photograph Capture: What You Need to Know
NTA requires all applicants to complete a live photo capture directly on the portal via a webcam or smartphone camera. This step was introduced to eliminate impersonation and fraud.
The live photo does NOT replace the scanned passport photo; you must provide BOTH. During live capture, sit facing a bright light source in front of a plain background without accessories or caps.
If using a laptop webcam with low resolution, you can complete the live capture step on your smartphone by logging into the NTA candidate portal via mobile browser.
Detailed NTA Rules for Candidate Signature
The candidate must sign on a clean sheet of white paper using a dark black or blue ink pen.
The signature MUST be in running handwriting. NTA official rules explicitly state that signatures written in CAPITAL / BLOCK LETTERS will be rejected.
While older bulletins specified 4 KB to 30 KB, newer NTA portal revisions accept up to 100 KB. Aiming for 10 KB to 30 KB ensures 100% compatibility across all NTA server checks.
Signatures in ALL CAPITAL LETTERS are flagged as invalid by NTA verification systems. Always sign in natural running script.
Dimension Requirements: Official Rules vs. Practical Tips
Official NTA Requirement: The JEE Main Information Bulletin mandates file size range (10–200 KB for photo, 4–30 KB for signature) and JPG/JPEG format. It does NOT enforce a rigid pixel height/width boundary on server upload, provided aspect ratio is reasonable.
Practical Tip: A standard 3.5 cm × 4.5 cm aspect ratio (approx 200×230 pixels) for photos and 3.5 cm × 1.5 cm aspect ratio (approx 140×60 pixels) for signatures displays cleanly and validates smoothly.
Step-by-Step File Preparation Workflow
Capture / Scan Image
Take a sharp photo of your passport picture or signature on white paper in good lighting.
Crop Whitespace
Use Modifyle Image Cropper to remove unnecessary background or paper margins.
Convert Format if Needed
If taking photos on iPhone (HEIC), use Modifyle HEIC to JPG converter to produce standard JPEG bytes.
Compress to Target KB Range
Compress photo under 200 KB (50–100 KB recommended) and signature under 30 KB (10–20 KB recommended).
Verify File Specs
Confirm file size on disk and verify that facial features or signature strokes remain sharp.
Common JEE Main Upload Rejection Mistakes
- Signing in capital letters or block print.
- Uploading files larger than 200 KB (photo) or 30 KB (signature).
- Uploading PNG, HEIC, or WEBP files instead of JPEG.
- Submitting photos with dark, colored, or cluttered backgrounds instead of white.
- Spectacle lens reflection obscuring candidate eyes.
