How it works
Exam-ready photo and signature in three steps. No editing skills, no software, no upload.
1
Pick your exam
Choose from 128 presets and the required pixels, KB band and DPI load automatically. Not listed? Type your own numbers.
2
Upload and adjust
Drag to position your face, pinch or scroll to zoom. Signatures get one-slider background clean-up. Add your name and the date if the board wants them printed on the photo.
3
Check and download
You get exact dimensions, a file inside the KB band, correct DPI — and a pre-flight report on blur, background and face position before you upload anything.

Questions
What photo size is required for CTET?
350 × 450 pixels as a JPEG between 10 KB and 100 KB, with a signature of 350 × 150 pixels between 3 KB and 30 KB. These are the sizes we currently list; confirm them in the notification published by CBSE.
My file is smaller than 10 KB. Will it be rejected?
Yes. 10 KB is a floor, not a suggestion, and portals reject files under it exactly as they reject oversized ones. This tool lifts an undersized file over the floor by appending blank JPEG comment data, which decoders ignore. The picture itself is untouched — some tools inject random noise into the image instead, which visibly degrades it.
Are my photos uploaded anywhere?
No. The resizing runs inside your browser using the standard canvas API. Nothing is sent to a server, there is no account, and the page keeps working offline once loaded.
Can I set the DPI?
Yes, and it defaults to 200 DPI here. Browsers write 96 DPI into canvas JPEGs, and some portals read that field and reject the file even when the pixel dimensions are correct. The value is written into the JFIF header of the file you download.
