Frequently Asked Questions

How do I compress an image to exactly 100 KB?

Enter 100 KB as the Target Size, upload your image, and click Compress. The binary-search algorithm finds the quality setting to hit your target.

What is a 100 KB image typically used for?

Most visitors need it for email attachments, CV photos and profile images — forms and portals often state an exact ceiling, and this page sets that target for you automatically.

Is 100 KB good enough for printing?

For small prints and on-screen use it is fine. For anything larger than a passport-size print, keep the original — at 100 KB the pixel count has already been reduced.

Can I convert format while compressing?

Yes. You can output JPEG, PNG or WebP while compressing to the target size.
