Converting your JPGs to WebP makes a website's images about a third lighter at equal quality, which improves load time and Core Web Vitals. Drop all the images of a page at once and download them as a .zip.

The formats
JPG
The universal photo format. It compresses with loss, which gives light files that open everywhere: browsers, phones, software, printers. It has no transparency, and each new save loses a little quality.
WebP
Google's image format, widely used by websites to load faster. At equal quality it weighs about a third less than a JPG, and it supports transparency and animation. Some older software and a few platforms still do not accept it.
Your files stay with you
The conversion runs in your browser, with your device's decoders. No file is uploaded, no copy is kept, and nobody but you sees your photos or videos. You can check it in the Network tab of your browser's developer tools: none of your files goes out.
Frequently asked questions
Do all browsers read WebP?
Yes, every current browser, including Safari on iPhone. Only old software and a few platforms handle it poorly.
Does it work in Safari?
Yes. Safari cannot write WebP itself: an encoder is then loaded in the page, and the result is the same.
Is the converter really free?
Yes, with no sign-up, no watermark and no limit on the number of files. The conversion runs on your device and costs us nothing, so there is nothing to charge you for.
Are my files sent anywhere?
No. They are read and converted in your browser, then saved straight to your device. No server receives them.
Is there a maximum size?
The limit is your device's memory. Photos and audio files go through without trouble; for a video of several gigabytes, a computer does better than a phone.
Does it work on a phone?
Yes, on iPhone and Android, in Safari, Chrome or Firefox. For video, an up-to-date browser is needed: it provides the decoders being used.
