Why WebP is usually the right answer
Smaller than PNG and JPG
WebP typically produces files 25–35% smaller than an equivalent JPG and dramatically smaller than a PNG photograph. For a site serving many images that is one of the largest page-speed wins available, and it needs no change to how the images are used.
Transparency survives
This is the part JPG cannot do. WebP supports a full alpha channel while still compressing lossily, so a transparent logo or product cutout stays transparent and still gets small. It is the only mainstream format that gives you both.
Lossy or near-lossless, your call
The quality slider works the same way as JPG. High settings are visually indistinguishable from the PNG while still saving substantial size; lower settings trade fidelity for further savings. Flat graphics tolerate high compression especially well.
Where WebP still trips people up
Every current browser supports it, but some older desktop software, a few print workflows, and certain upload forms still reject WebP. Use it for the web with confidence; keep a PNG or JPG copy when handing files to someone else.
Converted locally
The encode happens in your browser. Nothing is uploaded, so there is no file-size ceiling from a server and no copy of your artwork left anywhere.
