WEBP to PNG, locally

Drop in WEBP images and download PNGs that open anywhere, transparency intact. The conversion runs entirely inside your browser — nothing is uploaded, the network meter below proves it live, and it works with your wifi off.

How this converter works

Every modern browser decodes WEBP natively — it's a web format, after all. When you choose a file, the File API opens it in memory, the browser's decoder turns it into raw pixels with the alpha channel intact, this page draws those pixels onto a transparent canvas, and the canvas re-encodes them as a lossless PNG. The result comes back as a download link. No step involves a network transfer; the site is static files with no server that could receive an upload.

The readout's network meter arms the instant your first file is read and counts every request from that moment — it stays at zero, in green. For independent confirmation, watch the developer-tools Network tab stay silent while converting, or switch on airplane mode and convert anyway: after one visit this page is cached and works entirely offline. The methodology page walks through each verification.

The honest limits: PNG stores exactly what the browser decoded, so expect the file to grow — WEBP's efficiency is the reason websites use it, and PNG's losslessness costs space. Animated WEBP yields only its first frame, since PNG is a still format. And re-encoding strips any metadata from the output, which for shared images is usually the right default.

Frequently asked questions

Is my image uploaded anywhere?
No. Your browser decodes the WEBP itself, redraws it on a canvas inside this tab, and re-encodes it as a PNG — all in memory, on your device. The readout's network meter counts every request from the moment your file is read and stays at zero, and the methodology page shows how to verify that independently.
Why do so many images download as WEBP in the first place?
Websites serve WEBP because it's smaller than JPG or PNG at the same visible quality, which makes pages faster. Browsers open it fine — the friction starts when older apps, upload forms, and some editors refuse it. Converting to PNG gives you a file that opens everywhere, at the cost of size.
Is transparency preserved?
Yes. Both WEBP and PNG support transparency, and the conversion carries it across untouched — transparent stays transparent, no white background is added.
What happens with an animated WEBP?
PNG is a still format, so only the first frame is converted — the browser's decoder hands this page one frame, and that's what the PNG holds. For the full animation you'd want a GIF or video conversion, which this tool doesn't do.
Does converting lose quality?
No further quality is lost: PNG is lossless, so it stores exactly the pixels the browser decoded from your WEBP. If the WEBP was saved lossily by whoever made it, that loss already happened and no converter can undo it — but nothing new is discarded here.
