Many websites serve images as WebP because the files are smaller. When you right-click and save, you get the .webp file. Current browsers open it, but some older photo viewers, office software, print services and upload forms do not. Converting to JPG solves that.
Why you end up with WebP files
Quality and file size
Most WebP images on websites are already lossy. Converting to JPG decodes them and encodes again at quality 0.9, which adds a small second round of compression. At that quality the difference is rarely visible, but the JPG is often larger than the WebP, because WebP usually needs fewer bytes for the same look. The conversion is about compatibility, not size.
Transparency and animation
- Transparency: WebP can be transparent, JPG cannot. Transparent pixels are filled with white. Use WebP to PNG to keep them.
- Animation: animated WebP files convert to a single still image, taken from the first frame the browser draws.
Settings and output
- Quality: JPG is written at quality 0.9 where the format uses a quality setting. There is no slider on converter pages; use the Image Compressor if you want to choose the quality yourself.
- Size limits: images longer than 4096 px on either side are scaled down to 4096 px. If a converted file would be over 10 MB, it is reduced in steps until it fits.
- Batches: add several files; three are converted at a time. One file downloads directly, two or more come as a ZIP.
- Metadata: EXIF data (camera, date, GPS) and colour profiles are not carried into the new file.
Where the processing happens
Files are converted in your browser and are not uploaded.
Questions about this tool
I saved a picture from a website and it is a .webp file my app cannot open. What do I do?
Add the WebP file, press Convert Images and download the JPG. JPG opens in almost every app, editor and upload form.
Why is the JPG bigger than the WebP?
WebP usually needs fewer bytes than JPG for the same picture. Converting is about making the file open everywhere, not about making it smaller.
My WebP was animated. Why is the JPG a still picture?
A JPG can only hold one image, so you get a single frame, normally the first one.
The transparent parts of my WebP turned white. Can I keep them?
Not as JPG. Use WebP to PNG instead, which keeps transparency.
Can I convert many files at once?
Yes. Add several files and press Convert Images once. Three are converted at the same time. Download All gives you one ZIP file, or you can download each file on its own.
