WebP to PNG

Transparency kept, nothing uploaded.

Every browser can read WebP, so this works everywhere. The PNG is written at full resolution with transparency intact.

    What this tool does, exactly

    A WebP saved from a web page will not open in a surprising number of programs and upload forms. This turns it into a PNG, keeps its transparency, and measures the result — a PNG is lossless, so it is usually the larger file, and the page says by how much rather than pretending otherwise.

    What it does
    Decodes the WebP with your browser's own codec and writes the pixels out again as a PNG at the same size. PNG has an alpha channel, so a transparent WebP stays transparent — there is no background colour to choose because nothing needs one.
    Why the PNG is bigger
    WebP is a lossy format and PNG is not. The PNG records every pixel the WebP gave it, damage included, and it needs more bytes to do so. Converting cannot recover anything the WebP already threw away, so the reason to do it is compatibility, not quality.
    Animated WebP
    Only the first frame is converted. PNG has no animation of its own that most software honours, and a converter that silently drops 40 frames without saying so is the wrong kind of quiet.
    What is left in the file
    Nothing but the pixels. Any metadata the WebP carried — EXIF, colour profile notes, software tags — is stripped from what is written, and the result lists what was there before.

    About this tool

    Why will my program not open a WebP?

    WebP is a web format from 2010 that desktop software adopted slowly and some never did — older Photoshop, many upload forms, most email clients and a good number of print workflows still refuse it. A PNG is the safest thing to hand any of them, because everything that has opened a picture since the 1990s opens a PNG.

    Does converting to PNG improve the quality?

    No. A WebP saved from a web page has already been compressed with loss, and a PNG of it stores exactly that picture without adding or recovering anything. It will look identical and take more space. If you need a better picture, you need the original file the WebP was made from.

    Is the transparency kept?

    Yes. Both formats carry an alpha channel, so a WebP logo on a transparent background becomes a PNG logo on a transparent background. That is the difference from converting to JPG, where the transparency has to become a colour.

    Is my picture uploaded?

    No. Decoding and encoding both happen in this browser tab, and the site has no endpoint that could receive a file. The pictures people convert are often screenshots of something private, and a format change does not need a copy of them.
