Frequently asked questions

What image formats can I compress?

PixelKit can compress JPG, PNG, WEBP, AVIF, and BMP files. You can export the result as JPG, WEBP, or PNG.

Is it safe to use for private images?

Yes. The image tools run inside your browser, so your files are not uploaded to a server.

How much can I reduce the file size?

The result depends on the image content and quality setting. Photos often compress by 50-90% when saved as WEBP or quality-adjusted JPG.
