JPG to WEBP: cut image size for faster pages
Re-encoding a JPEG as WEBP usually shrinks the file by a quarter or more with no visible difference, which speeds up loading and saves bandwidth.
Smaller files, same picture
JPEG has served the web for decades, but its compression is old. WEBP was designed later with the same goal and generally produces a smaller file at the same visual quality.
For a photo-heavy page, converting the largest JPEGs is often the fastest available performance win, and it requires no change to the design.
How much smaller does it get?
On photographic content, savings of roughly 25 to 35 percent are common, and simple graphics with large flat areas can shrink even more.
The exact result depends on the image, so it is worth converting a copy and comparing both files side by side before replacing anything.
Browser support is no longer a concern
Every modern browser displays WEBP, including current versions of Chrome, Edge, Firefox, Safari, Opera and the default browsers on Android and iOS.
Only very old software and some legacy systems cannot read it, which is the main reason the reverse conversion still exists.
A practical workflow
Keep the original JPEG as your master, convert a WEBP for delivery, and check the result at full size before publishing.
Because the conversion runs in your browser, your images never leave your device.
