How to resize your CTET photo, signature
- CTET is already selected above, so the tool applies its rules for you.
- Select your photo from the gallery. Drag or zoom it so your face sits in the middle of the frame.
- Sign on plain white paper with a dark pen and select a picture of it.
- When every row shows a tick, download the files and upload them on the official form.
Common reasons uploads get rejected
- The file size is outside the KB range.
- The pixel size does not match.
- The format is not JPG. Some phones save HEIC or PNG.
- The background is dark or coloured, or there is a shadow on the face.
- The signature is too faint or cut at the edges.
Common questions
What is the CTET photo size?
CTET asks for a photo of 10–100 KB (3.5 × 4.5 cm) and a signature of 3–30 KB (3.5 × 1.5 cm), as JPG files.
How do I reduce my photo to 100 KB?
Choose CTET in the tool and add your photo. It finds the right quality automatically so the file lands inside 10–100 KB.
Why was my CTET photo rejected?
Usually the file is outside the allowed KB range, the pixels do not match, the format is not JPG, or the background is dark. The tool checks all of these before you upload.
Are my photos uploaded to a server?
No. Everything happens inside the browser on your own device. Nothing is sent to us.
Is this site connected with CTET?
No. This is an independent free tool. Always read the current notification at ctet.nic.in before you submit your form.
