WebP to PNG

How it works

WebP is a modern image format from Google that often produces smaller files than JPEG or PNG, but not every app, CMS, or print workflow accepts it yet. This tool converts WebP images to PNG directly inside your browser tab — no server, no upload, no waiting in a queue.

When you drop a file, Moyang reads its first bytes to confirm it's really a WebP image — not just guessing from the file extension — then hands the bytes to a background Web Worker. There, your browser's own image decoder unpacks the WebP data into raw pixels and re-encodes them as a PNG, which comes back to the page as a ready-to-download file. Your original file is never modified, and nothing ever leaves your device.

Because everything runs locally, there's no 10-conversions-a-day limit, no 100MB cap, and no processing queue — the kind of restrictions server-based converters impose to control their hosting bill. Convert one file or fifty; once a batch is done, download every result at once as a single ZIP.

Limitations

PNG doesn't support animation, so an animated WebP is converted using only its first frame — standard behavior for still-image conversion, not a bug. Because PNG is losslessly compressed, output files are usually larger than the source WebP, especially for photographic images; that's the natural trade-off for a format with zero compression artifacts. Images over 100 megapixels aren't converted — decoding runs entirely in your browser's memory, and a file that large risks crashing the tab before it even gets to PNG encoding.

FAQ

Is this WebP to PNG converter really free?

Yes — completely free, with no file size limits, no daily quota, and no account required. All conversion happens in your browser, so there's no server cost to recoup.

Do you upload my files to a server?

No. Your WebP files are decoded and converted to PNG entirely on your device, using your browser's own image engine. Nothing is ever sent over the network.

Is there a file size or batch limit?

No batch limit — convert as many files as you like. Individual images are capped at 100 megapixels, which covers even the highest-resolution phone cameras; this keeps conversion from overwhelming your browser on unusually large or corrupted files.

Does converting WebP to PNG lose quality?

No. PNG is lossless, so every pixel of the decoded image is preserved exactly. If the original WebP used lossy compression, that loss already happened before conversion — PNG won't add any more.
