About This Tool

Why use JPG to WebP?

Re-encode a JPG as WebP at quality 80. WebP's compression is more efficient than JPEG's at the same perceived quality, so the same photograph typically comes out 25 to 35 per cent smaller with no visible difference on screen.

This is worth doing when images are what makes your pages heavy, which is true of most sites. It is not worth doing to an image you plan to keep editing: the JPEG has already been compressed once, and re-encoding it to WebP compresses it a second time. Always convert from the highest quality original you have rather than from a file that has been through several rounds already.

Key Benefits

Smaller than JPEG

WebP's compression is more efficient at the same perceived quality, usually saving a quarter to a third of the file size.

Faster pages

Lighter photographs shorten Largest Contentful Paint, which is measured directly as part of page experience.

Converted locally

Decoding and re-encoding both happen in your browser, so the photograph is never uploaded.

JPG to WebP FAQs

How much smaller is WebP than JPEG?

Usually 25 to 35 per cent at the same perceived quality. The exact saving depends on the image — detailed photographs gain the most.

Does converting lose quality?

Slightly. The JPEG has already been compressed once and the WebP compresses it again. At quality 80 this is not visible at normal viewing size, but always convert from the best original you have.

Will older browsers show the image?

Every current browser supports WebP. Only genuinely ancient versions do not, and they are far below the threshold where a fallback is worth maintaining.
