How to use it

  1. Drag your JPG images into the box, or use the Choose images button to pick them from your computer or phone. Each one is converted to WebP as soon as you add it.
  2. WebP quality starts at 80. Lower it for a smaller file or raise it for more detail, then use the Convert again button.
  3. Download each WebP on its own, or all of them in one ZIP file.

How it works

Your browser opens each JPG image, draws it on a canvas and saves it again as a WebP at the quality you chose. Everything happens on your device: the tool never sends your images to a server.

Below quality 100, the WebP is lossy: higher quality keeps more detail and makes larger files; lower quality makes smaller files and gives up some detail. At quality 100, the WebP is lossless.

Safari can't create WebP images on its own, on Mac, iPhone or iPad, and every browser on iPhone and iPad uses its engine. There, the page loads libwebp, the WebM Project's open-source encoder, and creates each WebP with it, also on your device.

Example

You have a product photo saved as JPG and want to put it on your website as WebP. Drop it into the box at quality 80: you get a WebP with the same pixel dimensions, and next to the file you see its file size before and after.

Frequently asked questions

Are my images uploaded anywhere?

No. The conversion runs inside your browser and your files never leave your device, so it is safe to use with private images.

Does it work on iPhone or in Safari?

Yes. Safari doesn't create WebP images on its own, so in Safari and in any browser on iPhone or iPad the page loads libwebp, an open-source encoder, and runs it on your device. The first image takes a little longer while it downloads.

Does converting JPG to WebP lose quality?

Below quality 100, yes: the WebP is lossy, like a JPG, and higher quality keeps more detail but makes a bigger file. At quality 100, the WebP is lossless.

Will the WebP be smaller than my JPG?

It depends on the image and the quality you choose. Next to each file you see the JPG's size and the WebP's size, so you can compare them before you download. For a smaller file, lower the quality and use the Convert again button.

Does the WebP keep the photo's EXIF data?

No. The new WebP doesn't carry the JPG's metadata, such as camera details or GPS location, because the image is drawn on a canvas and saved again.

Can I convert several images at once?

Yes. Drop or pick several JPG images, then download them one at a time or all together in a ZIP file.
