Compress an image
Pick a target size (100 KB, 200 KB, or whatever you need) and get a file under it. It runs in your browser, so the file never leaves your machine.
How it works
The page re-encodes your image as JPG or WebP and searches for the highest quality setting that still lands under the size you picked. Dimensions stay untouched unless quality alone can't get there — only then does it step the image down in size, and never below 200 pixels on its short side.
Good to know
Very small targets look rough. Squeezing a big photo into 100 KB shows blocky edges and smeared detail. If the number is a form's upload limit, use the largest one it allows.
WebP usually wins. At the same target size, WebP holds more detail than JPG — choose it whenever whatever you're uploading to accepts it.
Need exact pixel dimensions instead of a file size? Use the Image Resizer.
Check for yourself that nothing is uploaded
You don't have to take our word for it. Every browser has a built-in panel that shows everything a page sends or receives over the internet. On a computer (this doesn't work on a phone):
- Press F12, or right-click anywhere on this page and choose Inspect.
- In the panel that opens, click the Network tab.
- Now use the tool: drop in an image and press Compress.
- Watch the Network list while it works. Nothing appears, because your image is never sent anywhere. All the work happens on your own computer.
