Why convert JPG to WebP?
WebP is an image format made for the web. At a similar visual quality, a lossy WebP is usually about a quarter to a third smaller than the same picture as a JPG. Smaller images load faster, use less mobile data and help a page pass speed checks such as Largest Contentful Paint. All current major browsers can display WebP.
How to convert JPG to WebP
- Drop one or more JPG images on the box, or paste an image with Ctrl+V.
- Pick the quality. The slider starts at 80, which suits most photos.
- Check the size before and after for each file, then download it or take everything as one ZIP.
Which quality should I choose?
| Quality | Good for | What to expect |
|---|---|---|
| 90 to 100 | Portfolios, product close-ups | Very close to the original, with smaller savings |
| 75 to 85 | Most photos on websites | No visible change at normal size, with good savings |
| 60 to 70 | Thumbnails, backgrounds, blog images | Strong savings, slight softening in fine detail |
| Below 60 | Tiny previews only | Visible blur and blocks in smooth areas |
WebP quality and JPG quality are not the same scale, so a WebP at 80 is not the same as a JPG at 80. Compare the preview, not just the number.
What happens to the picture
The JPG is decoded and encoded again as WebP, so it is a lossy to lossy conversion. Do this once, from your best original, and keep the original file. EXIF data such as camera model and GPS location is not copied into the WebP, which is also good for privacy. If the image has a rotation flag from a phone, it is applied so the WebP looks the same. PNG and other image files can be converted too, and transparent areas stay transparent.
Private and free
The conversion happens in your browser. Your photos are not uploaded and there is no sign up or limit.
More ways to work: the JPEG to WebP page keeps the original when WebP is not smaller, convert to a target file size to hit an upload limit, and bulk conversion handles whole folders. To go back, use WebP to JPG. Read JPG vs WebP to decide which format fits, and use the image compressor or the image resizer when you only need a smaller JPG. Working with other formats? Try PNG to JPG or HEIC to JPG.
