How to use the JPG to WebP
- Add your JPG files – select many at once to convert in bulk.
- WebP is preselected. The quality starts at 90%; lower it to about 80% for smaller website photos.
- Press “Convert”, then download each file or “Download All (ZIP)”.
Bulk JPG to WebP converter
Select or drop several JPG files at once and they are all converted with the same settings. When the batch is done, download every WebP in a single ZIP file instead of saving them one by one. You can add more images to the list before converting.
There is no signup and no daily limit. Because the conversion runs on your own device, a large batch simply takes a little longer on an older phone or laptop.
JPG to WebP and compress: which quality to choose
The quality slider controls how much the WebP is compressed. 80% is a good default for photos on websites. Use 85–90% for photos where fine detail matters, and 60–75% for thumbnails or when the smallest file size is the goal.
If the WebP has to fit a size limit or exact dimensions, use the Image Resizer & Compressor instead: it can resize, compress to a size in KB and save as WebP in one step.
Why websites use WebP
Images are often the heaviest part of a web page. Serving WebP instead of JPG reduces the amount of data visitors download, which makes pages faster on mobile connections.
If you run a WordPress or Shopify site, converting product photos to WebP before upload is a simple way to speed up your pages without plugins.
