Compress Image to 15 KB
Some state Public Service Commission and police-constable recruitment forms sit in an awkward middle band and ask for a photo or signature right around 15 KB — larger than a bare signature floor but well below the usual 50 KB photo cap. This mid-point trips people up because a signature over-compresses and a photo under-compresses at the same slider setting. The tool solves that by binary-searching quality to land just under 15 KB for whichever image type you feed it, entirely in the browser.

Good to know
- Handles the tricky 15 KB middle band, where photos and signatures need very different quality to fit.
- Aims just under 15 KB so the file clears the cap without dropping below a form's minimum.
- Works on JPG, PNG and WebP inputs and outputs a portal-friendly JPEG.
- Flattens transparency onto white so state-PSC signature scans don't render as black boxes.
- Reports the final size and quality so you can match a form's stated 15 KB requirement exactly.
