CUET UG Photo and Signature Size: KB and Format

These come from the CUET (UG) 2026 Information Bulletin published by the National Testing Agency on cuet.nta.nic.in (read on 13 October 2026). NTA publishes a new bulletin for every year, so check the one for your year before you apply.

• Scanned photograph: recent passport size photo in colour, with 80 percent of the image showing your face, ears included, without a mask, against a white background. JPG or JPEG, between 10 KB and 200 KB.
• Signature: JPG or JPEG, between 10 KB and 50 KB, clearly legible.
• Identity proof (only if you verify your identity by a method other than Aadhaar or DigiLocker): JPG or JPEG, between 10 KB and 200 KB.
• Disability or UDID certificate (if applicable): PDF, between 50 KB and 300 KB.
• Live photograph: captured with your webcam or phone camera inside the form while you fill it in.

For 2026 it is 10 KB to 50 KB. Some guides still say 4 KB to 30 KB, which was the rule in earlier CUET years. The safe choice is to aim for the middle of the current window, around 20 to 40 KB, which also keeps the strokes clear.

1. 1

   Start with a clear photo

   Use a recent colour photo against a plain white wall, in daylight, with no shadows. If it is a HEIC file from an iPhone, convert it with HEIC to JPG.

2. 2

   Crop so your face fills 80 percent

   Open Crop Image and crop much tighter than a normal passport photo: from just above your hair to just below your chin, with both ears inside the frame.

3. 3

   Resize and compress the photo

   Resize to about 350 x 450 pixels with Resize Image, then use Compress to 200 KB with a 10 KB minimum.

4. 4

   Prepare the signature

   Sign on white paper, crop tightly, resize to about 400 pixels wide, then open Compress Image set to 50 KB with a 10 KB minimum.

You only need the identity proof file if you do not verify your identity through Aadhaar or DigiLocker. Photograph the card flat and in focus, crop to its edges, and compress it to under 200 KB with Compress to 200 KB.

The disability or UDID certificate must be a PDF of 50 KB to 300 KB. Crop and resize a photo of the certificate to about 1400 pixels wide, compress it to around 150 to 250 KB, and turn it into a PDF with JPG to PDF. If you already have a large PDF, Compress PDF to 300 KB gets it under the limit.

• A normal passport crop where the face covers much less than 80 percent of the image.
• A signature under 10 KB because it was compressed for the old 4 KB minimum.
• PNG or HEIC files instead of JPG.
• A disability certificate PDF under 50 KB after heavy compression.
• A live photo taken in a dark room, which then does not match the scanned photograph.
