Code example
// Decode WebP, re-encode as PNG — all client-side
const img = new Image();
img.src = URL.createObjectURL(file);
await img.decode();
const c = document.createElement('canvas');
c.width = img.naturalWidth; c.height = img.naturalHeight;
c.getContext('2d').drawImage(img, 0, 0);
c.toBlob(b => saveAs(b, 'out.png'), 'image/png');FAQ
Why won't my WebP file open?
WebP is a modern web format: Windows Paint and older Office versions only gained support recently, and many CMSs export WebP by default while desktop tools lag behind. Converting to PNG restores universal compatibility.
Does converting WebP to PNG lose quality?
PNG is lossless, so a lossless-source WebP converts pixel-perfect. A lossy WebP has already discarded data — converting to PNG preserves exactly what remains, without further loss.
Is it safe to use an online WebP converter?
With PNGMill, nothing is uploaded — conversion runs in your browser, which you can verify with the network badge or your DevTools Network tab. Be cautious with converters that require uploads: your files sit on someone else's server.
Can I convert multiple WebP files at once?
Yes — drop as many as you like. Files are processed in a queue and you can download everything as a single zip.
