WebP to PNG: what happens
WebP is a modern, efficient format; PNG is a universally-supported lossless one that keeps transparency. Converting decodes
the WebP to raw pixels and re-encodes them as a PNG, all on a <canvas> in your browser. Nothing is
uploaded.
When to convert WebP → PNG
- An editor won't open WebP — many older tools accept PNG but not WebP.
- You need transparency in a universal format — PNG works everywhere.
- You want a lossless master — for further editing without new artefacts.
Want a smaller file instead of a lossless one? Convert to JPG, or run the result through the compressor.
Frequently asked
Are my WebP files uploaded anywhere?
No. The conversion runs on a canvas inside your browser tab. Nothing is sent to a server, and it works with Wi-Fi off after the page loads.
Does it keep transparency?
Yes. PNG supports an alpha channel, so transparent areas of a WebP are preserved in the PNG.
Why convert WebP to PNG?
Some editors and apps don't accept WebP, and PNG is a universally-supported lossless format — ideal when you need transparency and maximum compatibility.
Will the PNG be larger?
Usually yes. PNG is lossless while WebP is efficiently compressed, so expect a bigger file. That's the trade-off for compatibility and lossless quality.
