How to compress an image to 100 KB

  1. Add your picture.
  2. The target is already set to 100 KB. Change it if you need a different size.
  3. Press the button. The tool tries qualities and, if needed, smaller dimensions until the file fits.
  4. Download the result and check it before you upload it.

Good to know

  • A photo around 800 pixels wide usually keeps good quality at 100 KB.
  • Photographs of documents are harder. Text needs sharp edges, so keep the dimensions up and let the quality drop a little instead.
  • WEBP gets noticeably better quality than JPG at this size, if the site accepts it.

Questions

Is 100 KB the same as 0.1 MB?

Roughly. A kilobyte is 1024 bytes, so 100 KB is 102,400 bytes, a little under a tenth of a megabyte.

Will text in a scanned document stay readable?

Usually, but check it. If the text goes soft, scan at a lower resolution and a higher JPG quality rather than the other way round.

Can I do several pictures at once?

Yes. Add as many as you like and download them together as a ZIP.
