SizeRightPhoto for GST university admission applications
Admission applications to the GST cluster universities need a colour JPG photo of 300 × 300 pixels with a white background, no larger than 100 KB. Turn on “White background” and make it here.
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.
Photo rules
| File | Size | Max file size |
|---|---|---|
| Colour photo (JPG) | 300 × 300 px | 100 KB |
- A recent, clear colour photo with a white background. If your background isn’t white, turn on “White background” above.
- Photos in a school or college uniform are not accepted.
- Both ears must be visible, and the face should fill about two-thirds of the photo’s height. Use zoom to place the face that way.
- Photos with any software effects are not accepted. The photo is later used for biometric verification, and a mismatch can cancel the application.
- No signature upload is mentioned for this application.
These rules come from Prothom Alo’s report of the 2025–26 GST admission notice. They can change each year, so check the current notice on gstadmission.ac.bd before applying. Universities outside GST, such as Dhaka University, have their own rules; use “Custom size” to match their notice.
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”.
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.
