CTETPhoto & Signature Upload Requirements Guide

The Central Teacher Eligibility Test (CTET) mandates that every candidate upload a strictly compliant passport-style photograph and a handwritten signature during online registration. Non-compliant files are among the most common reasons for form rejection before the application is even reviewed. For the CTET photo size, the required pixel dimensions are 350 x 450 pixels, with a file size between 10 KB and 100 KB in JPEG format. The background must be light-colored. The CTET portal does not require any printed text overlay on the photograph. For the CTET signature size, your handwritten signature on white paper must be scanned or photographed to produce an image of 280 x 120 pixels, compressed to 3–30 KB. Signatures must be written using black or blue ink and must not be in capital letters. Our free online CTET photo resize tool compresses and crops both files locally inside your browser — your images are never uploaded to any server. Specifications are sourced directly from the 2026 Notification and last verified on 2026-05-15.

How to Resize CTETPhoto & Signature Online

Select the asset type
Click the 'Photo' tab to resize your photograph, or the 'Signature' tab to process your signature scan. Both use separate CTET-specific dimension presets.
