Why your downloads are WebP files
Websites serve images as WebP because the files are 25–34% smaller than comparable JPG files according to Google’s WebP compression study, which makes pages load faster. Our guide Why do images save as WebP? explains the rest. When you save one of those images — a product photo, a recipe picture, a profile image — you get a .webp file. Your browser shows it fine, but many other programs do not.
This converter changes it into a JPG, the most widely supported photo format there is. It uses your browser’s built-in WebP decoder (Chrome, Edge, Firefox and Safari 14+ all have one) and its JPG encoder, so the conversion is instant and never leaves your device.
Settings
| Setting | Range | Default | What it does |
|---|---|---|---|
| Quality | 50–100% | 92% | JPG compression level. Lower means smaller files with more artifacts. |
| Background for transparent areas | Any color | White | Fills see-through pixels, because JPG can’t store them. |
The preview shows the decoded WebP, with transparent areas as a checkerboard; the quality and the background color are applied when the JPG is saved. For a logo going onto a dark slide, for example, pick the slide’s color instead of white.
WebP to JPG vs. WebP to PNG
Both conversions are useful, but for different images:
- JPG is best for photos. Files stay reasonably small and open everywhere, from email attachments to photo printers.
- PNG keeps transparency and sharp text perfectly, at the cost of much bigger files. Use WebP to PNG for logos, icons and screenshots.
If you received AVIF images instead, the same approach works with AVIF to JPG. And to go back to WebP for your own website, use JPG to WebP.
Lossy and lossless WebP
A WebP file can be lossy (like JPG) or lossless (like PNG), and it may contain transparency in either case. Photos on websites are almost always lossy WebP, and converting them to JPG is the natural choice. Logos and illustrations are often lossless WebP with a transparent background; those convert to JPG too, with the background color filled in, but PNG keeps them closer to the original.
Common questions about the result
- Is the JPG bigger than the WebP? Usually yes, since WebP compresses better. At 92% quality expect a somewhat larger file; lower the quality slider if size matters.
- Is the resolution changed? No. The JPG has exactly the same width and height as the WebP.
- What about metadata? The JPG is made from the pixels, so EXIF or XMP data stored in the WebP is not copied.
- File names:
photo.webpbecomesphoto.jpg; several files come back in one ZIP.
No upload, no account
Many online converters upload your images to process them on a server. Here, the work is done by the page running in your browser: nothing is uploaded, there are no tracking cookies, and the page keeps working offline after it has loaded. There is no limit set by us on how many files you convert. To make the JPG lighter afterwards, try Compress Image.
