Convert images to WebP for free, in your browser
Drop your JPG, PNG, GIF or BMP images and turn them into WebP instantly. Everything happens on your device: your photos never leave your computer or phone.
WebP is an image format created by Google that is much smaller than JPG or PNG at a very similar visual quality. Switching your site's images to WebP is one of the easiest ways to make it load faster, use less mobile data and score better on the speed metrics Google looks at.
This converter uses the image encoder already built into your browser. Pick one image or many at once, set the quality with the slider and download each result or all of them in one go. Next to every file you will see the original size, the new size and the percentage saved, so you can find the sweet spot between weight and sharpness.
For photos, a quality between 75 and 85 is usually invisible to the eye and cuts the size in half or more. For screenshots, icons or drawings with few colours, go for 90 or higher. If a PNG was already heavily optimised the WebP may come out slightly larger; in that case just keep the original.
Frequently asked questions
Are my images uploaded to a server?
No. The conversion runs entirely in your browser with JavaScript; your images never leave your device and the tool even works offline once loaded.
Which formats can I convert to WebP?
Any image your browser can open: JPG, PNG, GIF (first frame only), BMP, AVIF or WebP itself to recompress it.
Is PNG transparency kept?
Yes. WebP supports an alpha channel and transparency is preserved.
What quality should I choose?
For photos, 75 to 85. For screenshots, logos or illustrations, 90 or higher. Compare the size and the result and adjust.
Is there a limit on images or file size?
There is no fixed limit: it depends on your device's memory. You can convert many images in a batch.
