About this tool
WebP was built for the web. At the same visual quality, a WebP photo is typically 25–35% smaller than the JPG it came from, which means faster pages and lower bandwidth. Every current browser supports it, so it is a safe choice for images on your own site.
Because both formats are lossy, converting re-compresses the photo. Converting from the original camera JPG gives the best result; converting a JPG that has already been compressed heavily will not shrink it much further without visible loss.
For anything that leaves the web — printing, attaching to documents, older apps — JPG remains the most widely accepted format, so keep your originals or use the reverse conversion when you need them.
Frequently asked questions
How much smaller will my photos be?
Converting JPG to WebP usually makes photos 25–35% smaller at a matching quality setting, sometimes more. Each file shows its before and after size, and a file that would not get smaller is flagged rather than presented as a saving.
Does every browser support WebP?
Yes, every current version of Chrome, Edge, Firefox and Safari supports WebP. Very old browsers and some desktop apps do not, which is where JPG is still the safer choice.
Can I convert back to JPG?
Yes, WebP converts back to JPG with Klonum’s WebP to JPG converter, which the Reverse button on the JPG to WebP page opens. Expect a small further loss, because both formats are lossy.
