Why convert PNG to WebP?
PNG is lossless and keeps transparency, but for the web it's often heavier than it needs to be. WebP gives you a much smaller file at similar quality and, crucially, also supports transparency — so your logos, icons and graphics stay clean while your pages load faster and use less bandwidth. Every modern browser supports it, which makes it a great default for website assets. Just remember a few older apps and devices can't open WebP, so for images meant to be downloaded and opened anywhere, PNG can be the safer pick. ConvertPixie does it instantly on your device — no app to install and nothing uploaded to a server.
Your images never leave your device
ConvertPixie reads your PNG and writes the WebP right here in your browser. Nothing is uploaded or stored — ideal for images you'd rather keep to yourself.
Frequently asked questions
Does converting PNG to WebP keep transparency?
Yes. WebP supports transparency, so any transparent areas in your PNG are preserved in the WebP.
Why convert PNG to WebP?
WebP is much smaller than PNG at similar quality, so your pages load faster and use less bandwidth — while still keeping transparency for logos and graphics.
Is WebP supported everywhere?
All modern browsers support WebP. A few older apps and devices don't, so if you need maximum compatibility for downloads, PNG can be the safer choice.
Are my images uploaded anywhere?
No. The conversion happens entirely in your browser. Your PNG images never leave your device and nothing is sent to a server.
Can I convert several PNG files at once?
Yes. Add as many PNG images as you like, convert them all, then download each WebP or grab them together as a ZIP.
