Published 5 November 2026 by Kloora Tools

Quick answer: use the Compress Image to KB tool, type the size you need and download the result. It works for any target from about 10KB up to many megabytes.

Step by step

Open the free Compress Image to KB tool in Chrome or Safari.
Tap the box and choose your photo.
Type the size you need in the target size box and keep the unit on KB.
Pick JPG for the widest support.
Download the result and check its size in your file manager.

Tips

Check whether the form counts in KB or MB.
Choose WebP only when the site allows it.
You can compress many photos at once and download them as a ZIP.

A common mistake

Renaming a big file to .jpg. That does not shrink it. The image must be re-saved smaller.

Privacy

The Compress Image to KB runs in your browser, so your files are not uploaded and no account is needed.
