Shrink JPEG, PNG and WebP images by quality or to a target size.

**Runs in your browser. Nothing is uploaded.** Your files are processed on this device and never leave it. You can even switch off your internet once the page has loaded.

Formats: JPEG, PNG, WebP. This is an interactive tool: open [the page](https://trysecretgrid.com/tools/image-compressor) in a browser to use it.

## How it works

1. Add one or more images. They stay in your browser.
2. Pick JPG or WebP, then compress by quality or to a target size such as 100 KB.
3. For a target size, the tool finds the highest quality that fits, and only shrinks the image if it has to.
4. Download each compressed copy. Metadata, including location, is removed.

## Questions

### How do I get an image under 100 KB?

Choose Target size and set At most to 100 KB. The tool searches for the best quality that fits, and scales the image down only if even the lowest quality is too large.

### JPG or WebP?

WebP is usually 25–35% smaller at the same visual quality and works in all modern browsers. Choose JPG when a site or app only accepts JPG.

### Will it look worse?

At 70–80% quality most photos look the same to the eye. Lower settings save more space with visible softening.

### What about PNG screenshots?

PNG is lossless, so the compressor saves them as JPG or WebP, which are far smaller. Transparent areas become white in JPG.
