Compress an image to under 100KB

Squeeze an image under a strict 100KB limit automatically — free, private, and processed on your device.

Some sites enforce a tight 100KB limit for avatars, thumbnails or ID uploads. Set the target to 100KB and the compressor works out the quality — and, if needed, you can resize the dimensions too for the smallest possible file.

It's all done in the browser with no upload, so it's safe even for photos of documents and IDs.

Frequently asked questions

How can I get an image under 100KB?

Set the target to 100KB in the compressor. For very small limits, also reduce the pixel dimensions with the resizer — smaller dimensions make hitting 100KB much easier.

Is 100KB enough for a clear image?

For avatars, thumbnails and small photos, yes. For large detailed photos you may need to reduce the dimensions as well to stay under 100KB while looking sharp.

Does it upload my image?

No — it runs entirely in your browser, so nothing is uploaded.
