Convert WebP to PNG

Free, in your browser — no upload. Transparency preserved. Your PNG will be larger than the WebP.

or drop the image here

RoundCut converts WebP to PNG entirely in your browser, using the native image encoder. Nothing is uploaded. PNG is the format desktop apps actually open — Photoshop, Word, Preview, older Windows tools. Alpha transparency is preserved pixel-for-pixel. The output PNG is always larger than the WebP source, often two to ten times larger — expected, not a bug.

How to convert WebP to PNG

Drop a WebP file on the upload area (or click to pick one). The conversion runs the moment the file lands — there is no "Convert" button to chase. When the result is ready, the stats line shows the input and output size, and the Download button saves the PNG to your device with the original filename and a new extension. If you want to convert another image, just drop the next one — each file runs from scratch, no queue and no server pre-processing. It works the same on desktop and on mobile.

Transparency is preserved

Both WebP and PNG support 8-bit alpha transparency, so every transparent pixel in your WebP stays exactly as transparent in the PNG. A logo on a transparent background comes out as a logo on a transparent background — no white fill, no halo, no premultiplied edges. If your WebP has soft semi-transparent edges (shadows, anti-aliased text, glow), they survive the round trip pixel-for-pixel. This is the main reason people convert to PNG instead of JPG: JPG would flatten the alpha to a solid color, PNG keeps the cutout clean.

WebP or PNG — when to use each

Keep WebP when the image lives on the web: it is roughly 25 to 35 percent smaller than PNG at the same visual quality, so pages load faster and bandwidth costs less. Switch to PNG when something offline needs the file — Photoshop, Word, PowerPoint, Preview, older Windows tools and most email clients still refuse to open WebP. PNG is the format every desktop app understands, which is the usual reason people convert in the first place. If your final destination is a website, stay on WebP; if it is a document, a print job, an editor or an email, convert to PNG.

Your file will be larger — here's why

PNG uses lossless DEFLATE compression; WebP uses a newer, more efficient algorithm. Converting from WebP to PNG always grows the file — typically 26 percent larger for graphics, and two to ten times larger for photographs. A 3 MB WebP photo can easily become a 14 MB PNG. This is the cost of switching to a format that opens everywhere; the PNG is not lower quality, just bigger on disk. If file size matters more than compatibility (uploading to a website, sending by email with a tight attachment cap), keep the WebP instead.

Your privacy

The conversion runs in the browser's native image engine. Nothing is uploaded, nothing is logged, nothing is queued on a server. If you open DevTools and watch the Network panel while you convert, you will see zero outbound image requests. The same code path runs on every browser — there is no server fallback, no hidden cloud step, no telemetry on the contents of your file. Most online converters upload your WebP, process it on their machine and send the PNG back; here, the file never leaves the device.

Frequently asked questions

Why can't Photoshop or Word open my WebP file?

WebP is a modern web format, and a lot of desktop software still ignores it. Photoshop only added native WebP support in late 2022, so older versions need a plugin. Word, PowerPoint, Preview on older macOS and most legacy Windows tools simply refuse the file. Converting to PNG is the universal workaround — every app that handles images at all will open a PNG.

Does this converter preserve transparency?

Yes. WebP and PNG both support 8-bit alpha, so transparent pixels stay transparent, semi-transparent pixels keep their exact opacity, and there is no white fill or halo around cut-out subjects. A logo on a transparent background converts to a PNG with the same transparent background — pixel-for-pixel, no flattening, no premultiplication.

Why is the PNG file larger than the WebP?

Because PNG is lossless and WebP is more compressed. PNG stores every pixel exactly, using a 1990s compression algorithm; WebP uses modern prediction that squeezes the same image into less space. Going from WebP to PNG always grows the file — about 26 percent for graphics, often 200 to 1000 percent for photos. A 3 MB WebP photo can become a 14 MB PNG. That is expected; it is the price of compatibility.

Does converting WebP to PNG lose any quality?

The conversion itself adds zero new loss — PNG is lossless, so the pixels the browser decoded from the WebP are written byte-accurate. But if the original WebP was saved in lossy mode (most web WebPs are), those existing artifacts are already baked into the pixels and cannot be removed by going to PNG. The PNG will look identical to how the WebP looked on screen, not better.

Is it safe to convert here? Does my image get uploaded?

Your file never leaves your browser. The conversion runs entirely on your device using the platform image engine — no upload, no server, no data collection. You can verify it with DevTools open: there are zero outbound image requests during conversion. If your image is sensitive (a document, a personal photo, work material), this is the difference that matters.

What happens to animated WebP files?

Only the first frame is converted. PNG supports animation through the APNG extension, but this tool does not produce APNG — the output is a single still image of frame one. If you need to preserve every frame of an animated WebP, a dedicated GIF or APNG tool is the right choice; for a static thumbnail, the first frame is usually what you want anyway.
