How do I compress a photo to under 15 KB without losing clarity?

Upload the original photo above. The tool picks the highest JPEG quality that still fits under 15 KB, so you don't have to guess with a slider. A plain background and good light keep the face sharp.

What is 15 KB photo size in pixels?

KB measures file size and has no fixed pixel equivalent. This page outputs 260×340 px by default. If your form gives different pixel or cm dimensions, follow the form, or tick Keep original dimensions.

Will my photo be exactly 15 KB?

No. This is a maximum-size tool. It searches for the highest JPEG quality within 15 KB, but the final size depends on your image and can be much smaller.

What if my form requires between 10 KB and 15 KB?

The tool enforces the 15 KB maximum, not a 10 KB minimum. If the output is below 10 KB, try a clearer, larger original and check the new result before uploading.

Can I reduce a photo to 15 KB on an Android phone or iPhone?

Yes. Open this page in your phone's browser, tap the upload box, choose the photo from your gallery and download the result. No app is needed.

Can I convert a PNG or phone photo to a 15 KB JPG?

Yes. JPG and PNG files are accepted and the download is always a JPEG under 15 KB.

Is my image uploaded to a server?

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

Tips for a clean 15 KB file

•This tool centre-crops to 260×340 px. Leave room around your face and check that the preview has not cut off important details.
•If your form requires 10–15 KB, check the output is at least 10 KB. A result below that minimum is not suitable, even when the tool says it fits the 15 KB maximum.
•Use a plain, light background and daylight — busy backgrounds use up KB and look blocky at 15 KB.
•Use a clear original photo, not a screenshot. Increasing JPEG quality cannot restore detail missing from the source.

Common mistakes

•Uploading a screenshot — screenshots are already compressed and often produce blocky JPEGs. Use the original photo instead.
•Ignoring dimensions — a file can be the right KB but the wrong shape. This page sets 260×340 px automatically.
•Cropping too tightly — leave a small margin around the head and shoulders so the form does not cut the face.
•Wrong background — busy backgrounds eat KB and can get rejected. Plain white or light works best.

Troubleshooting

The result is still too big: Start with a smaller source file or crop closer to the face. If the form allows a smaller size, try 12 KB.
The result is too small: The source image may be very low resolution. Upload a larger original photo and retry.
My form rejected the upload: Double-check both the KB limit and the pixel dimensions in the form. Some forms also require exact aspect ratios (e.g. 3.5×4.5 cm).
