How to use it
Add your JPG files
Drag one or many JPG pictures onto the page, or choose them from your phone or computer.
Check the format
WebP is already selected as the output format. Choose a quality if you want a smaller or sharper file.
Convert and download
Press Resize images and download each WebP, or all of them as a ZIP.
Why convert JPG to WebP?
WebP is a modern image format that all current browsers can show. For photos it often makes files around a quarter to a third smaller than JPG at similar quality, which saves bandwidth and speeds up pages.
Before you replace pictures on a website, check that the places where you use them accept WebP. Email programs, some printers and many upload forms still ask for JPG.
Tips for converting JPG to WebP
- A quality of 75 to 85 usually gives a clearly smaller file than the JPG with no visible difference.
- Keep the original JPG files. Some older programs and upload forms do not accept WebP.
- Converting a JPG that was already compressed heavily does not bring back lost quality.
- Add many pictures at once and download them together as a ZIP file.

Can I convert JPG to WebP on my phone?
Yes. It works in the browser of any modern phone, with no app to install.
Is it free?
Yes. There is no signup, no watermark and no limit on the number of pictures.
