A comfortable middle ground. Enough detail for a printed admit card, small enough for strict portals.

How it works

  1. Upload any JPG or PNG from your phone or computer.
  2. We fit it to 400×500 px and tune JPEG quality until the file lands between 30 and 40 KB.
  3. Download and upload it straight to the form.

Everything runs on your device — your image is never sent to a server.

Where a 40 KB limit shows up

  • University portals
  • Bank application forms
  • Recruitment boards

Tips for a clean 40 KB file

  • •Check whether the form measures the limit in KB or KiB — our output clears both.
  • •Save the original file too. If a portal later asks for a larger version you will need it.

Frequently asked questions

Is 40 KB enough for a passport-style photo?
Yes. At 400×500 px, 40 KB holds plenty of detail for both on-screen checks and admit-card printing.
Is my image uploaded to a server?
No. ShantiTools compresses the image entirely inside your browser — the file never leaves your device.
