How to use WebP to PNG

  1. 1

    Add the WebP files

    Drop up to 10 .webp images of up to 25 MB, for example pictures saved from a website. Other formats can join the batch too.

  2. 2

    Keep PNG selected

    PNG is pre-selected and needs no quality setting. Choose JPG instead if you want small files for photos.

  3. 3

    Let it convert

    Each image is decoded and written as an optimised, lossless PNG as soon as it is added.

  4. 4

    Download

    Save single PNGs from their cards, or everything as converted-png.zip.

Limits and Pro

Up to 10 images per batch and 25 MB per image, with no limit on pixel size beyond what your browser can hold.

Pro handles up to 500 WebP files per batch, each as large as 4 GB. See Pro

About WebP to PNG

WebP is the image format Google introduced in 2010; it can be lossy, built on the VP8 video codec, or lossless, and it supports transparency and animation. Websites love it because pages load faster, which is why a picture you save from a browser so often ends up as a .webp file. Older software is less keen: some versions of Photoshop, Microsoft Office, Windows Photo Viewer, many CMS upload fields and print services won't open it.

This page turns each WebP into a PNG with exactly the same pixels and dimensions. PNG is lossless, so nothing is lost in the conversion, and the alpha channel comes across intact, including soft semi-transparent edges around a logo or a cut-out product. The PNG is compressed with OxiPNG to keep it as small as a lossless file can be, but expect it to be larger than the WebP: a lossy WebP photo often grows three to ten times, while flat graphics and icons grow much less. Metadata inside the WebP, such as EXIF or XMP, is not copied.

What the conversion can't do is restore detail. If the WebP was saved with lossy compression, its blur and artefacts are preserved faithfully in the PNG. Animated WebP files are reduced to their first frame. When the image is a photo with no transparency and size matters more than editing, choose JPG under Convert to instead.

Privacy

Your browser decodes the WebP itself, with a WebAssembly fallback for older browsers, and OxiPNG writes the PNG in a Web Worker in this tab. The codecs are fetched from this site once you add an image. The pictures never leave your device and nothing about them is logged.

Features

Transparency kept

Alpha channels and soft edges carry over to the PNG exactly.

Lossless output

Every decoded pixel is stored as is, optimised with OxiPNG.

Batch and ZIP

Convert a folder of WebP images at once and download them together.

Other targets

Switch to JPG, WebP or AVIF any time; files are converted again automatically.

WebP to PNG: frequently asked questions

Why convert WebP to PNG?
Because PNG opens everywhere. Image editors, word processors, presentation software, older Windows and macOS viewers, and many upload forms accept PNG but stumble over WebP. PNG is also lossless, so you can edit and save it repeatedly without the quality dropping, which makes it a good working format for graphics you plan to change. Transparency carries over, unlike a conversion to JPG.
Why is the PNG much bigger than the WebP?
Most WebP images on the web use lossy compression, which discards detail you can't easily see. PNG has to store every pixel exactly, so a photo can become three to ten times larger even after OxiPNG optimisation. Graphics with flat colours, such as logos and diagrams, grow far less. If file size matters and you don't need transparency, convert to JPG instead.
Is transparency kept when converting WebP to PNG?
Yes. PNG supports a full alpha channel, so transparent backgrounds and semi-transparent edges stay exactly as they were in the WebP. The thumbnail cards show transparent areas over a checkerboard, so you can confirm it before downloading. Only a conversion to JPG would flatten the transparency, onto white or the fill colour you choose in the Quality panel.
Do animated WebP files work?
They convert, but as a still image: the PNG contains only the first frame of the animation. PNG itself can't hold an animation in a way most apps understand. To keep the motion, save the original WebP, or convert it with a tool that outputs GIF or MP4. Static WebP files, which are by far the most common, convert normally.
Is WebP to PNG conversion lossless?
The conversion step is: every decoded pixel of the WebP is written to the PNG unchanged, with no recompression on top. Whatever the WebP lost when it was first saved with lossy settings, however, stays lost, because PNG can only preserve what is there. If you have the original JPG or PNG that the website made the WebP from, that source will always be better.
