How do I reduce a photo to 12 KB?

Upload it above. We resize to 250×330 px and step the JPEG quality down until the file lands under 12 KB.

Will the photo still be usable at 12 KB?

For a well-lit, tightly cropped face, yes. If it looks blocky, retake the photo in daylight against a plain background.

No. ShantiTools compresses the image entirely inside your browser — the file never leaves your device.

12 KB is a very tight cap — usually an older portal that has never raised its limit. We shrink the photo carefully so the face stays readable.

•At 12 KB the background is what costs you detail. Shoot against a plain wall before you compress.
•Crop tightly around the head and shoulders — empty margins waste every kilobyte you have.
