Why WebP files need converting
WebP is an image format from Google that makes pictures smaller than JPG at the same visual quality. Every current browser shows WebP, so websites use it widely. Outside the browser, support is less complete. Some older photo viewers, editing programs, print shops, marketplaces and upload forms still reject .webp files or show an error. JPG works almost everywhere.
Typical situations:
- you saved a product photo or picture from a website and an app won’t open it
- a form or online shop only lets you upload JPG or PNG
- you want to print a picture at a photo kiosk
- you are sending an image to someone using older software
How to use this converter
Choose one or more WebP files, or drop them on the box above. Each one is converted in your browser and gets its own download button, along with the old and new file size.
Choosing a quality setting
85% suits most pictures. If the WebP was already heavily compressed, as many web images are, raising the JPG quality above 90% mostly adds file size without bringing back detail. Lower it to around 70% when you need a small file for email or a chat app.
What changes in the converted file
- Transparency becomes white. Logos and cut-out product shots with see-through backgrounds will get a white box behind them.
- Animation is dropped. Only the first frame is kept.
- Metadata stored in the WebP is not copied.
- Dimensions stay exactly the same.
If you need transparency, a lossless copy, or plan to edit the picture, convert WebP to PNG instead.
Converting a whole folder of WebP images
In the file picker, open the folder and press Ctrl+A (Cmd+A on a Mac) to select every file, then confirm. The converter works through them one at a time so your browser stays responsive, and each finished JPG gets its own download button. On a phone, tap “Browse” or “Files” in the picker to choose several images from a folder rather than from your photo gallery.
Questions
Why do images I save from websites end up as WebP?
Many websites send images as WebP because the files are smaller and load faster. When you right-click and save, you get the file the site sent, even if the page once showed it as a JPG.
What about animated WebP files?
JPG can only hold a single still image, so an animated WebP becomes a JPG of its first frame.
What happens to transparent parts?
They are filled with white, because JPG has no transparency. Use the WebP to PNG converter if you need to keep them.
Will the JPG look worse than the WebP?
At the default 85% quality the difference is very hard to see. The JPG is usually a bit larger than the WebP, because WebP compresses more efficiently.
