The best conversion on this list, if the target is the web
WebP was designed to replace both PNG and JPEG on the web, and for PNG sources it usually delivers: a screenshot or a logo commonly drops by half or more, with transparency intact and no visible difference at a sensible quality setting.
Every current browser supports WebP, so for an image that will only ever be displayed on a web page there is very little argument left for shipping the PNG instead.
Where WebP still bites
Outside the browser. If the file is going into a document, an email attachment, a print workflow or desktop software on a colleague machine, WebP is the format that generates the confused reply. PNG or JPG is the considerate choice there.
For images that must stay pixel-exact, note that this converts to lossy WebP by default. At 90% that is invisible for almost everything, but if you need a guaranteed-identical copy - an asset going into a design system, an image being compared programmatically - keep the PNG.
Frequently asked questions
- Does WebP support transparency?
- Yes, fully. Unlike JPEG, converting a transparent PNG to WebP keeps the alpha channel intact.
- How much smaller will the file be?
- For screenshots, logos and diagrams, typically 50% or more. For photographs already saved as PNG, the saving is usually much larger again.
- Do all browsers support WebP?
- Every current browser does. Support outside the browser - desktop editors, office software, print workflows - is still patchy.
- Is this lossless?
- The output is lossy WebP at the quality you choose. At 90% the difference is invisible in practice, but it is not a bit-exact copy of the PNG.
