About the Compress Image to 300 KB

300 KB gives a photo plenty of room to look detailed while still being small enough for portals, email, and listings that cap uploads. It is a good pick when 100 KB or 200 KB would soften an important image too much. This tool targets 300 KB locally, so a heavy original comes out crisp and comfortably under the limit without anything being uploaded.

Is it free with no sign-up?
