WebP is the format speed tools recommend when they say “serve images in next-gen formats.” All current browsers display it. Converting your JPG photos to WebP at quality 80 is the simplest way to cut image weight on a site without touching the design.
This page sets the output to WebP. Convert a whole folder, download the ZIP, and upload the WebP files in place of the JPGs.
How to convert JPG to WebP
Add JPG photos
Use the original exports if you have them. Converting a heavily compressed JPG carries its artifacts across.
Leave quality around 80
That matches a good web JPG. Add a max width if the photos are larger than your layout ever shows them.
Download and swap
Replace the JPG references in your page or CMS. Keep the original JPGs as your masters.
What you get from WebP
Smaller pages
A quarter to a third less image weight per photo adds up on galleries and product listings.
Same look
At matched visual quality, people cannot tell the WebP from the JPG on screen.
WordPress and other CMSs
WordPress has accepted WebP uploads since version 5.8. Most hosted shop and site builders accept it too. If yours does not, it may already convert images itself; check before doing both.
Keep sending JPG by email and to upload forms. Many of them still reject WebP.

JPG to WebP questions
Is WebP better than JPG?
For websites, usually: smaller at the same look, with transparency support. For email and uploads, JPG is still safer because it is accepted everywhere.
Will converting JPG to WebP reduce quality?
Any re-encode loses a little. At quality 80 the difference is not visible on normal photos.
Can I convert JPG to WebP in bulk?
Yes. Drop the whole set and download a ZIP. There is no file count limit.
How do I open a WebP on my computer?
Any current browser opens it. Windows Photos and macOS Preview also do. Use the WebP to JPG page if an app refuses it.
