WebP is the go-to format for the web: it is usually 25 to 35% smaller than a JPG of similar quality, supports transparency like PNG, and every current browser displays it. Drop any images here and get WebP versions ready for your website, blog or online store.
How to convert images to WebP
- Drop your images in the box above, or click to pick them. You can add as many as you like.
- WebP is already selected as the output format. Switch on other formats if you want them too.
- Optional: open Advanced Settings to resize by percentage, width or height, and add more sizes.
- Click Start Conversion, then download each file or all of them at once. Nothing is uploaded: the conversion runs in your browser.
Why convert images to WebP?
Lighter images mean faster pages, better Core Web Vitals and less mobile data for your visitors. WebP keeps alpha transparency, so it can replace both JPG photos and PNG graphics. Animated GIFs are converted to a still WebP of their first frame.
Frequently asked questions
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox, Safari (since version 14) and their mobile versions all display WebP, which covers practically every visitor today.
Does WebP keep transparency?
Yes. Transparent areas from PNG, GIF or AVIF files stay transparent in the WebP output.
Are my images uploaded?
No. The conversion runs entirely in your browser, on your device. Your images are never uploaded to a server, so this works for private and confidential files too.
