Compress a photo to the exact KB size you need

Type a limit — 20 KB, 50 KB, anything — and get the smallest file that still looks right.

  • Nothing uploaded
  • No sign-up, free
  • Works on phones

How it works

  1. Add your photo (JPG, PNG or WebP).
  2. Pick a preset, or type your own KB target.
  3. Set a minimum size too, if your form needs one.
  4. Compress, then download.
  • Crop to head & shoulders first — it compresses much cleaner.
  • Save as JPG, not PNG — PNG stays large for photos.
  • Plain, well-lit background gets you a smaller file at better quality.
  • Still blocky? Resize the pixels down first, then compress.
Signature scan? Dark ink on plain white paper, tight crop, good light.

FAQs

How do I get a photo to exactly 20 KB?

Type 20 in the target box and press Compress. It finds the best quality that still fits under 20 KB.

Will it look blurry?

Some detail is lost, but it always picks the highest quality that fits your limit — cropping tight helps most.

Is my photo uploaded anywhere?

No. It's processed on your device only. It even works after you go offline.
