One JPG file at a time
At 80% the result is visually indistinguishable from the original JPG for nearly any photograph.
How JPG to WebP conversion works
The browser decodes the JPG into pixels, paints them on a canvas and re-encodes them with the built-in WebP compressor. There is no intermediate conversion and no change in dimensions.
saved % = (JPG size − WebP size) ÷ JPG size × 100
WebP uses block prediction and a more efficient entropy stage than JPG, so it needs noticeably fewer bytes for the same perceived quality. It is the format PageSpeed Insights recommends for content images.
How much you save depends on the photo: images with flat areas or smooth gradients shrink a lot, while heavily textured ones (grass, sand, noise) shrink less.
Worked example
A 480 KB JPG product photo converted to WebP at 80% quality lands around 320 KB: 33% less to download for every visitor.
Frequently asked questions
- Is it worth moving my JPGs to WebP?
- For a website, almost always: fewer bytes means faster loading and better Core Web Vitals. For archiving or printing, keep the original.
- Do I lose quality when converting?
- A little, because WebP is also lossy and the source JPG already lost some. Above 75% quality the difference is not noticeable.
- What happens to the EXIF data?
- It is dropped. The browser only copies pixels to the canvas, so GPS location, camera model and other metadata are not carried over.
- Can I convert several photos at once?
- The tool works one file at a time so it can show you the resulting size of each conversion and let you tune the quality with real numbers.
