Turn .webp pictures into PNG files that every program opens. A PNG keeps the transparent parts of a WebP and loses no detail, which suits logos, icons and screenshots.

    Everything you enter is processed in your browser and is never sent to a server.

    Browsers:Chrome57+Edge79+Firefox52+Safari15+Opera44+Samsung Internet7.0+BrowsersYour browser must also be able to show WebP pictures, which the data above does not cover.

    How to use

    1. Drop your .webp files onto the box, or choose them. You can add up to 50 at once.
    2. The format is already PNG. A PNG is lossless, so there is no quality to set; Optimize PNG makes the file smaller but slower. You can also shrink the size.
    3. Download each PNG, or press Download all to get a ZIP.

    Examples

    logo.webp with a transparent background
    → logo.png, still transparent
    PNG keeps the alpha channel.
    photo.webp
    → photo.png
    The picture is not changed by the conversion, but the PNG is usually much larger than the WebP.
    An animated WebP
    → A PNG of its first frame
    A PNG holds one picture.
    An 800 × 600 lossy WebP, Keep original size
    → An 800 × 600 PNG
    The PNG has the same pixels, including any blockiness the lossy WebP already had. It does not get sharper.
    IMG_0042.WEBP and img_0042.webp in the same batch
    → IMG_0042.png and img_0042-2.png in the ZIP
    Names that match when the case is ignored get -2, -3 so nothing is overwritten.

    How it works

    This page is the image converter with WebP to PNG already chosen. Your browser decodes the WebP and the PNG is written losslessly and, with Optimize PNG ticked (it is by default), shrunk by OxiPNG, an open-source optimizer. The conversion keeps the width and height of the original unless you pick a new size.

    What “lossless” means here

    The step from WebP to PNG loses nothing: every pixel the browser decodes is written into the PNG as it is. But the step that matters happened earlier, when the WebP was made. If it was saved as a lossy WebP, the fine detail is already gone, and the PNG is a faithful copy of that smaller picture, not of the original. Only a WebP that was saved in lossless mode carries the same pixels as the picture it came from.

    Why the file grows

    Kind of picture PNG compared with the WebP
    Photo Often several times larger
    Screenshot or diagram Closer, sometimes about the same
    Logo with flat colours Close, and sometimes smaller

    PNG compresses by finding repeated patterns, which suits flat colours and sharp lines but not the endlessly varied pixels of a photo. A lossy WebP simply drops that variation.

    When PNG is the right choice

    Choose PNG when you need transparency in a program that does not read WebP, when the picture will be edited again and you do not want more generations of loss, or when you are making a screenshot or logo that must stay crisp. For a photo whose size matters more than exactness, a JPG from the WebP to JPG page is far smaller.

    Frequently asked questions

    Does WebP to PNG lose quality?
    No further loss is added. The PNG holds exactly the pixels the browser shows for the WebP. If the WebP was made lossy, the artifacts already in it remain.
    Why is the PNG so much bigger?
    PNG stores every pixel without discarding anything, while a lossy WebP discards detail the eye barely notices. For photos a PNG is often several times larger; for flat graphics the sizes are close.
    Is transparency kept?
    Yes. Transparent and partly transparent pixels stay as they are.
    Should I use PNG or JPG?
    Use PNG for logos, icons, screenshots and anything with transparency or sharp edges. Use JPG for photos when the size matters.
    Will the PNG look better than the WebP?
    No. A lossy WebP has already thrown detail away, and a PNG cannot bring it back; it only stops further loss. Convert to PNG to edit or to open the picture in a program that does not read WebP, not to improve it.
    What does Optimize PNG do?
    It runs the finished PNG through OxiPNG, an open-source tool that re-packs the same pixels into fewer bytes. The picture is identical, only the file is smaller, and it takes longer. It is ticked by default; clear it if you are converting many large pictures and want it to finish sooner.
    Which programs need PNG instead of WebP?
    Mostly older image editors, office programs and upload forms, or a print shop. A current browser shows WebP, but a program that does not know the format reports an unsupported file, and a PNG avoids that.
    Can I turn an animated WebP into an animated PNG?
    No. This page keeps only the first frame, and the result is an ordinary single-picture PNG.
    Are my pictures uploaded?
    No. They are converted in your browser.

    Guides

    Version history
    • 1.0.4 — Adds what lossless means for a WebP that was already lossy, why the PNG is larger, what Optimize PNG does, and when PNG is the right choice, with more examples and questions.
    • 1.0.3 — Puts the format and quality options and the size options on one line on a wide screen, instead of two lines with empty space beside them.
    • 1.0.2 — Makes the search title and description state the supported task, key formats and privacy benefit more clearly.
    • 1.0.1 — Reports conversion completion and failure to connected workflows, so batch runs wait for the full result and ignore cancelled or superseded work.
    • 1.0.0 — First release.
