Compress a JPEG to 100 KB
Re-compressing a JPEG is a different job from converting one: the file has already lost detail once, so a second pass has less to work with. Aiming at a size rather than a quality number avoids the trap of asking for "better" and getting a bigger file.

How it works
- Add the JPEG you need to shrink.
- The target is set to 100 KB.
- Press the button to compress, then save it.
Questions
Why did raising the quality make my file bigger before?
Because a quality number is meaningless without knowing what the file was saved at originally. Asking for higher quality than the source stores more data without restoring any detail. That is why this page asks for a size instead.
Does compressing a JPEG twice hurt it?
A little, yes: each save discards some detail permanently. One extra pass to meet a form limit is normally fine; repeated round trips are not.
