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.

Frequently Asked Questions

Why do some state PSC and police forms ask for 15 KB?
A few state PSC and police-constable portals set a lower photo/signature band around 15 KB to save server space, sitting between the 10 KB signature floor and the 50 KB photo norm. Always read the specific advertisement, as the number varies by state.
Is 15 KB enough for a passport-style photo?
It's tight but workable for a head-and-shoulders photo, especially once you resize to the pixel size the form asks for. The tool keeps the best quality that fits, so faces stay recognisable at 15 KB.
The form gives a range like 15-40 KB — what should I target?
Aim for the upper end for a photo (better quality) and the lower end for a signature. Targeting just under 15 KB is the safe choice when 15 KB is the hard maximum.
Does compressing twice hurt the image?
Re-compressing an already-JPEG image adds a little extra loss. For best results, start from your original scan or photo and compress to 15 KB once.
Where does the compression happen?
Entirely in your browser. No upload, no server, no account — your photo or signature stays on your device.
