Photo and signature for Chittagong University admission applications
CU admission applications need a 300 × 300 pixel photo (200 KB) and a 300 × 80 pixel signature (150 KB), uploaded to the applicant’s profile. The pixel sizes are the usual ones, but the KB limits are higher, so the files can stay sharper.
The photo keeps its pixel size where it can, and quality is lowered only as much as needed. If the limit is very low, the photo is made a little smaller instead of turning blocky.
PNG keeps every pixel exactly, so files are much bigger. Under a low KB limit the photo is made smaller, and at exact pixel sizes it may not fit at all. For photos, JPG is usually the better choice.
Leave width and height empty to only reduce the file size. With one of them, the other follows the shape chosen above.
The sizes asked for
| File | Size | Max file size |
|---|---|---|
| Photo | 300 × 300 px | 200 KB |
| Signature | 300 × 80 px | 150 KB |
- The “Application Process” guide on CU’s admission website asks for a recent, clear, formal photo with the face uncovered at “Size: 200KB; Resolution: 300x300 pixels”, and a signature at “Size: 150KB; Resolution: 300x80 pixels”.
- Both are uploaded from the applicant’s profile on admission.cu.ac.bd.
These sizes come from the guide for the 2025–26 session. Before applying for 2026–27, check the current guide on admission.cu.ac.bd. If the size has changed, use “Custom size” above.
For a good photo
- Use a recent, sharp photo.
- Keep the face in the middle of the frame with a little space above the head.
- Follow any rule in your notice about background colour or clothing.
- If you need a white backdrop, turn on “White background”.
For a clean signature
- Sign on white paper with a black pen.
- Photograph it straight on, in good light, without a shadow.
- Let the signature fill most of the frame.
- With “Clean paper” on, grey or shadowed paper turns white.
Common questions
Is my photo uploaded to a server?
No. Cropping, resizing and compressing all happen inside your browser. The photo never leaves your phone or computer.
Will the file really be under the KB limit?
Yes. The tool finds the best quality that stays under the limit. It counts 1 KB as 1000 bytes, so the file is under the limit whether a portal counts 1000 or 1024.
Is it free?
Yes, completely free. There is no account and no watermark.
Does the file keep the photo’s location data?
No. The new file carries none of the camera’s extra data, such as GPS location.
Does it work on a mobile phone?
Yes. It works in any modern mobile or desktop browser.
