How to convert JPG to WebP
On a website, online shop or blog, images are usually the heaviest part of the page. WebP compresses better than JPG: at similar visual quality the file is normally noticeably smaller, and every current browser displays it.
This converter turns your JPG photos into WebP so you can upload them to your site or CMS and improve load times.
Step by step
- Click Select file and choose the JPG (up to 50 MB).
- Check that Convert to shows WEBP.
- Click Convert image to WEBP.
- Download the WebP and check its final size before uploading. For a whole gallery, use the Workspace and the ZIP download.
How much you save and what quality is used
The WebP is encoded at quality 88, a high setting that prioritises the photo looking the same. The saving depends on the image: it is usually clear for photographs, but a JPG that was already heavily compressed may only shrink a little. That is why it is worth comparing sizes before and after.
Converting does not recover detail: the WebP starts from the JPG exactly as it is.
Tips for using WebP on the web
Resize the image to the dimensions it will actually be shown at first: a 6000-pixel photo in an 800-pixel column is wasted weight, whatever the format.
EXIF metadata is removed, which also strips GPS location and saves a few kilobytes. Orientation is applied to the image, so it will not appear rotated on your site.
Frequently asked questions
- Do all browsers support WebP?
- Yes, current desktop and mobile browsers all support it.
- How much smaller is WebP than JPG?
- It depends on the photo. It is usually noticeably lighter, but check the result: if the JPG was already heavily compressed, the saving is smaller.
- Will the image look worse?
- At quality 88 the difference in photos is hard to spot.
- Can I convert all my site's images at once?
- Yes. The Workspace has no limit on files per batch and gives you everything in one ZIP. Each image can be up to 50 MB.
