Photo and signature for BUET admission applications
BUET admission applications need a colour photo of about 300 × 350 pixels, up to 75 KB, and a signature of about 300 × 80 pixels, up to 20 KB, both JPG on a white background.
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.
BUET’s rules
| File | Size | Max file size |
|---|---|---|
| Colour photo | 300 × 350 px | 75 KB |
| Signature | 300 × 80 px | 20 KB |
- Both must be JPG/JPEG with a white background. If your photo’s background isn’t white, turn on “White background” above; for the signature, keep “Clean paper” on.
- Nothing may be written or attested on the photo. Blurred or distorted photos and signatures are not accepted; they are checked against you in the exam hall.
- The signature limit is only 20 KB. The tool finds the best quality that fits.
These sizes come from BUET’s “Guidelines for Admission to Undergraduate Program” for the 2025–2026 session. Before applying for 2026–27, check the current guidelines on www.buet.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.
