Drop your CUET photo, get a 200×230 px JPG between 10 and 200 KB — the NTA upload window, minimum included. For the signature, set Target to 50 KB and Min to 10 KB. Nothing is uploaded; it runs in your browser.
The NTA application form for CUET (UG) takes the scanned photograph as a JPG/JPEG between 10 KB and 200 KB, commonly specified at 200×230 pixels (the ~3.5×4.5 cm passport shape), and the scanned signature as a JPG/JPEG between 10 KB and 50 KB. Both ends of each window are enforced. This page is preset to the photo spec — drop your photo and download the result. For the signature, change Target to 50 KB and Min to 10 KB above; a tight signature crop at high quality can land under the 10 KB floor, in which case PixFit pads the file up with a spec-valid JPEG comment (plain-text padding bytes; no pixels change, portals accept it). No official pixel size is consistently published for the signature — keep it a wide strip cropped close to the ink, and whatever the upload screen itself asks for wins.
Older guides quote a 4 KB signature floor. That was an earlier year's window (4–30 KB), and at least one big 2026 guide still has the stale figure in its summary while its own table says 10–50. Current 2026 sources agree on 10–50 KB; if your year's Information Bulletin says otherwise, the bulletin wins.
CUET registration also requires a live photo captured in the form itself (webcam or phone camera) alongside the uploaded photograph — that one can't be made in advance, so good lighting and a plain background at registration time matter. NTA uses the uploaded photo, the live capture and the signature for automated identity checks across application scrutiny, admit-card generation and exam day, and files that meet the size window but fail clarity or face-detection checks can still be rejected — a sharp, well-lit source photo matters as much as the byte count.
The photograph must be recent (colour or black-and-white), against a white background, with about 80% face visible including both ears, no cap or mask (regular spectacles are fine). The signature goes on plain white paper in black or blue ink, in running hand — all-capitals signatures are treated as invalid. PixFit fixes bytes and pixels only; the Information Bulletin for your session on cuet.nta.nic.in is the authority if it disagrees with anything here — NTA has revised these windows between years. Sitting NEET (UG) too? Its windows are different: see the NEET photo & signature page. Applying for postgraduate admission instead? CUET PG is a separate test with its own bulletin (and a signature window that moved).
These files identify you: face and signature, tied to your application number. PixFit re-encodes them entirely in your browser — nothing is uploaded to any server, and the re-encode strips EXIF metadata (including GPS) from phone photos as a side effect. An iPhone HEIC can be dropped straight in; the JPG it produces is what you upload.
