Compress image to 100 KB
Photo or signature under 100 KB
or drop files here
Your files never leave your device: Compress image to 100 KB runs inside your browser, so nothing is uploaded, stored or seen by anyone. It is free and needs no sign-up.
100 KB suits larger photos, scanned signatures with a stamp, and documents saved as a picture. It is also a handy size for pictures you send on WhatsApp or attach to a web form that rejects anything bigger.
For a scanned document, check the result at full zoom: small print is the first thing to blur. If it does, ask for a larger target such as 200 KB.

Questions and answers
- What is the difference between 100 KB and 200 KB?
- About twice the room for detail. Use 100 KB when the form insists on it, and 200 KB when you want text in a scanned document to stay easy to read.
- Why not just resize the picture myself?
- You can, but guessing the right size takes many tries. This tool lowers quality and size automatically until the file is under 100 KB, so you do it once.
- Are my files uploaded anywhere?
- No. Your browser opens and processes the files itself, and nothing is sent to our servers. You can check this yourself on the How we do it page.
- Is my original photo changed?
- No. You get a new file to download and the original stays where it is. Check the result before you replace anything.
- Is Compress image to 100 KB really free?
- Yes. There is no sign-up, no watermark and no limit on how many files you use it for.
