Compress Image to 100 KB

100 KB is the most common upload limit on the web — job application portals, e-mail systems, CMS thumbnails and government forms all seem to love it. The good news: almost any photo can reach 100 KB and still look genuinely sharp.

How to compress a photo to 100 KB

  1. 1

    Open your image

    Drag in the photo that needs to be under 100 KB — straight from your phone or computer, in any common format including HEIC.

  2. 2

    The 100 KB target is preset

    The compressor immediately works toward 100 KB, showing a live preview and the exact output size vs your original. Most photos land between 90 and 100 KB on the first pass.

  3. 3

    Download your file

    One click saves the compressed copy, named and ready for the form or e-mail that demanded it. The original on your device is untouched.

What to expect at 100 KB

A typical phone photo (3–8 MB) reaches 100 KB at about 1200–1600 pixels wide with modest quality reduction — perfectly crisp on screens, completely fine for documents and applications.

Documents and ID-style photos hold up especially well: faces and even text stay clearly legible, because the compressor protects edges and spends the budget where your eye goes.

If you're attaching several photos to one e-mail, compressing each to 100 KB keeps the whole message under typical 25 MB caps with room to spare — use the Batch tab and download a ZIP.

Frequently asked questions

Will a photo still look good at 100 KB?

Yes. 100 KB at 1200–1600 pixels is enough for sharp on-screen viewing. Side by side with the original at full zoom you may spot differences; at normal size most people can't.

My form says 'max 100 KB' — will the output always fit?

The compressor targets just under 100 KB and shows the exact byte size before you download, so you'll never get rejected on size. If a result lands at 102 KB, nudge the target to 95.

Does compressing remove the photo's metadata?

Re-encoding drops most embedded metadata, which forms usually don't need. To inspect or strip metadata deliberately — including GPS location — use the EXIF Data Remover tool.
