How to do it, step by step
- Select the JPG or JPEG files.
- Adjust the Quality (80% to 85% usually balances size and sharpness).
- Click Convert all and check the saving in the queue.
- Download everything as a ZIP.
When this is useful
Optimize a site’s images
Pages with WebP photos tend to load faster, especially on phones.
Product photos for an online store
Convert the whole catalog keeping a good look with less weight.
Tips for a good result
- Use the batch summary (size before and after) to decide whether it is worth switching.
- Keep the original JPGs saved: reconverting already compressed files degrades the image.
What this tool does not do
- Old browsers and programs may not open WebP; confirm support where you will use it.
- In large photos (above 8 megapixels) the app uses a faster writing mode, which may produce a slightly bigger file.
- Depending on the image, the WebP can come out bigger than the JPG: the app shows the result.
Frequently asked questions
- Is the WebP always smaller?
- In most photos yes, but not always. The queue shows the new size of each file.
- Does it lose quality?
- At 80%–90% quality the difference is usually hard to notice, but there are losses, since the WebP in this converter is also lossy.
