WebP to PNG

About this converter

This free WebP to PNG converter turns a WebP image into a widely-supported PNG, keeping any transparency exactly as it was. PNG is what you want when the image has a cut-out background, when you are about to edit it, or when the software you are feeding will not accept WebP.

Everything runs in your browser — your image is never uploaded to a server.

PNG, not JPG — when transparency is the reason

If your WebP has a transparent background, PNG is the only sensible destination of the two common choices.

JPG has no alpha channel. Convert a cut-out to JPG and every transparent pixel becomes a solid colour, usually white — so a logo you meant to place on a dark slide arrives inside a white rectangle. There is no way around it; the format simply cannot store the information.

PNG keeps the full 8-bit alpha channel, the same as WebP. That means not just fully transparent and fully opaque, but all 254 values in between — which is what soft shadows, feathered edges and anti-aliased curves are made of. A logo converted to PNG keeps its clean edge against any background you later put it on.

If your image is a photograph with no transparency, JPG will give you a much smaller file. PNG is for transparency, sharp edges and text.

Why the PNG comes out larger

Expect the file to grow, sometimes a lot. This is normal and worth understanding.

PNG is lossless. It stores every pixel exactly and throws nothing away. WebP, in the mode most web images use, is lossy — it achieved its small size by discarding detail.

So the conversion takes a compressed approximation and writes it out with perfect fidelity. PNG faithfully preserves every compression artefact the WebP already contained, at full lossless cost. A 200 KB WebP photograph can easily become a 2 MB PNG.

The important consequence: converting to PNG does not restore quality. Detail discarded by lossy WebP is gone. PNG guarantees nothing more is lost from this point forward, which is exactly what you want before editing — but it cannot recover what was already thrown away.

If the WebP was lossless to begin with, as logos and icons often are, the PNG will be close in size and pixel-identical.

Why this is the right format before editing

PNG being lossless is the practical reason to convert before working on an image.

Every time a lossy image is opened, changed and saved again, it is re-compressed and loses a little more. Do that across five rounds of edits and the damage is visible — blotchy gradients, haloes around edges. Generation loss compounds quietly.

Convert to PNG first and that stops. You can crop, retouch, resize and save as many times as you like with no further loss, because PNG re-saves are exact. Export to a lossy format once, at the end, when the image is finished.

This is the standard working pattern: lossless while you work, lossy when you publish.

Where PNG is simply required

Beyond transparency and editing, several systems accept PNG and refuse WebP outright:

• Print workflows — most print shops take JPG, TIFF, PDF and PNG, and not WebP
• Older Photoshop — native WebP support only arrived in version 23.2 (2022)
• Office documents — older Word and PowerPoint installations will not insert a .webp
• Upload forms — job portals, government sites and many marketplaces allow only JPG and PNG
• Favicons and app icons — tooling expects PNG almost universally
• Email templates — several email clients still show nothing for a WebP
• Design handoff — PNG is the safe format to send to someone whose software you do not know

How to use it

• Upload your WebP — click the upload area or drag and drop a .webp file
• Keep transparency — leave it on to preserve the transparent background, or turn it off and pick a background colour
• Download — save your PNG

Good to know

• The file will usually get bigger, because PNG is lossless. That is the format working correctly, not a fault.
• Quality is not restored. Detail already discarded by lossy WebP cannot come back.
• Animated WebP loses its animation. PNG holds one frame. Use GIF or MP4 for something that moves.
• Check the image on a dark background if transparency matters. A white halo around a cut-out is easy to miss against a white page.
• For a photograph with no transparency, JPG is the better target — far smaller for the same visible result.
• Resize before converting if the PNG will be large. Halving the dimensions quarters the pixel count.

Common questions

Will my transparent background survive the conversion?

Yes. PNG supports the same full 8-bit alpha channel as WebP, so transparency comes through exactly — including partial transparency, soft shadows and feathered edges. This is the main reason to choose PNG over JPG, which cannot store transparency at all and would fill it with a solid colour.

Why is my PNG so much bigger than the WebP?

Because PNG is lossless and most WebP images are lossy. The WebP got small by discarding detail; PNG stores every remaining pixel exactly, artefacts included, with nothing thrown away. A 200 KB WebP photo can easily become a 2 MB PNG. If the original WebP was lossless, the two will be much closer in size.

Does converting to PNG improve the image quality?

No. Detail discarded when the WebP was compressed is permanently gone, and no conversion can recover it. What PNG guarantees is that nothing further will be lost from this point on, which is exactly why it is the right format to convert to before you start editing.

Should I convert to PNG or JPG?

PNG when the image has transparency, contains text or sharp edges, or is about to be edited. JPG when it is a photograph with no transparency and you want a small file. Converting a transparent image to JPG replaces the transparency with a solid colour, which is the mistake people most often regret.

Can I make the background transparent during conversion?

Only if it already is. Transparency that exists in the WebP is preserved, but the converter cannot invent it for an image with a solid background. To remove a background that is actually there, use the Background Remover, then convert.

What happened to my animated WebP?

PNG holds a single still frame, so an animated WebP loses its animation and you get one frame. For something that needs to move, convert to GIF or to a video format instead.

Is my image sent to a server?

No. Your browser decodes the WebP and writes the PNG on your own device, so the file never leaves your computer. The tool continues to work with your connection switched off.
