How to use

3. Press Compress, check the preview, then download the result.

About 15KB

15KB limits show up on some older government and recruitment portals for signatures and thumb impressions. Dark ink on plain white paper compresses far better than a coloured background.

For scale, 15KB is about 0.01MB. A typical 3MB phone photo has to shrink roughly 205 times to fit, so expect lower resolution and some softness. Cropping first keeps more detail.

Tips for best results

Portals that ask for 15KB usually also want a JPG file. This tool outputs JPG. If the result looks too soft, upload a higher-resolution original, because tiny or already-compressed images have little left to give.
