Compress image to 20 KB
Photo or signature under 20 KB
or drop files here
Your files never leave your device: Compress image to 20 KB runs inside your browser, so nothing is uploaded, stored or seen by anyone. It is free and needs no sign-up.
20 KB is a common upper limit for signatures and small passport-style photos on exam and job application forms. At this size a face photo stays recognisable if the picture is small and the background is plain.
Check what the form asks for before you start: some portals want a minimum size as well as a maximum, and some name exact pixel sizes. The tool gets you under the limit; it cannot know the rest of the rule, so read the notice.

Questions and answers
- Will a 20 KB photo be sharp?
- It will be small and a little soft, which is normal for this limit. If the form allows more, a larger target such as 50 KB keeps more detail.
- Does the tool make the file exactly 20 KB?
- It aims to get under 20 KB, which is what most forms check. If the form also demands a minimum size, compress to a slightly larger target instead.
- 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 20 KB really free?
- Yes. There is no sign-up, no watermark and no limit on how many files you use it for.
