Batch convert WebP to PNG with alpha transparency preserved automatically, plus an optional PNG size optimizer.
PNG supports transparency natively, so nothing needs to be flattened. Your WebP's alpha channel is decoded and written straight into the PNG, and any file that carries it gets an Alpha tag so you can confirm it before converting.
Most tools just wrap your image in a PNG container and stop, leaving you with a file several times larger. Drag the optimizer slider to quantize the palette, like pngquant, and watch the size drop while transparency stays intact.
Conversion runs on your browser's own Canvas engine. Images are never sent to a server, so there's nothing to leak and no upload wait.
Drop in dozens of WebP files, apply the same optimizer setting to all of them, and download every result together in a single ZIP.
Drag the before/after slider on any converted file to inspect the result on a checkerboard backdrop, and see the exact size difference before committing.
Convert as many images as you like - no watermark, no account, no catch.
Drag and drop .webp files, or click to browse from your device. Files with transparency or animation are tagged automatically.
Leave the optimizer at 256 for a lossless PNG, drag it lower to shrink the file, or flip on target size for an exact KB budget instead.
Grab each PNG individually, or all at once as a ZIP - no sign-up required.
WebP is a modern, highly efficient format that supports transparency, but it isn't accepted everywhere. PNG stores every pixel losslessly, keeps the alpha channel intact, and has been supported essentially everywhere for decades - which is why it's the safer choice when an image needs to be edited again later or opened in older software.
Tip: leave the optimizer at 256 for a byte-faithful lossless PNG. If the source is animated, only its first frame carries over - PNG doesn't support animation.
imgxcolor's WebP to PNG converter decodes your WebP files and re-encodes them as PNG directly in your browser - no software, no file uploads, no cost. Drop in one WebP or a whole batch, optionally shrink the result with the palette optimizer, and download the results in seconds.
It's built for anyone who needs a WebP to open in software or on a platform that doesn't support it, while keeping every pixel of transparency exactly intact.
WebP wins on efficiency, but PNG still wins on being universally supported and easy to edit further.
| Property | WebP | PNG |
|---|---|---|
| Compression | Lossy & lossless | Lossless only |
| Typical size at similar quality | Smaller | Larger |
| Transparency (alpha channel) | Supported | Supported (copied exactly) |
| Animation | Supported | Not supported (first frame only) |
| Software & platform support | Near-universal in browsers, gaps elsewhere | Universal, including editing and design tools |
| Best for | Web delivery, smaller size | Maximum compatibility, further editing |
WebP is smaller and more efficient than older formats, but it's still a newer format, which means it isn't accepted everywhere. Some design tools, older software, certain CMS uploaders, and plenty of everyday apps and platforms still don't open .webp files at all, while PNG has been supported essentially everywhere for decades.
PNG is also the safer choice specifically when transparency matters and needs to survive editing untouched. Because PNG stores color data losslessly, a logo, icon, or product cutout converted from WebP keeps every edge exactly as it was, with no compression artifacts introduced by the conversion itself.
Leave the slider at 256 colors for a fully lossless, pixel-exact PNG with the alpha channel untouched. Drag it lower and the tool quantizes the image to that many colors using a real palette encoder - similar to pngquant - which can shrink flat graphics and logos dramatically with little visible difference, while transparency is preserved at every level. Photos generally band and look blotchy below 200 colors, so the tool nudges you toward a sensible range based on what it detects in your image.
Only the first frame is used. PNG is a still-image format with no animation support, so any additional frames in an animated WebP are discarded during conversion. Animated files are flagged with an Animated tag in the file list before you convert.
Every conversion runs locally with JavaScript and the Canvas API. Your images are never uploaded, stored, or transmitted, which makes this converter safe for client assets, personal photos, or any file you'd rather not send to a third-party server. There are no accounts, no sign-ups, and no usage limits.
No. imgxcolor decodes and re-encodes every WebP locally using your browser's Canvas engine, so nothing is ever uploaded and the result appears instantly.
No. WebP's alpha channel is decoded exactly and copied into the PNG's own alpha channel, pixel for pixel. Any file carrying transparency is flagged with an Alpha tag in the file list so you can confirm it at a glance.
WebP is a modern, highly efficient format, while a plain PNG re-encode stores every color exactly, so a straight conversion is often several times larger. This tool includes an optional PNG size optimizer that quantizes the color palette, similar to pngquant, to shrink the result back down without touching transparency.
Leave it at 256 colors for a fully lossless, pixel-exact PNG. Drag it lower and the tool quantizes the image to that many colors using a real palette encoder, which can shrink graphics and logos dramatically with little to no visible difference, while transparency is preserved at every level.
Only the first frame is used. PNG is a still-image format with no animation support, so any additional frames in an animated WebP are discarded during conversion.
Yes. Drop in as many WebP files as you like, apply the same optimizer or target-size setting to the whole batch, convert them together, and download every result at once as a ZIP.
No hard limit - only what your device's memory can comfortably handle. The tool is free, has no watermark, and doesn't require an account.
