    WebP supports transparency, so your PNG's alpha channel is preserved. Higher quality means larger files.

    How to convert PNG to WebP

    1. Drop your .png files onto the drop zone, or click to browse.
    2. Set the quality — around 0.8 to 0.9 gives a great size-to-quality balance.
    3. Click Convert to WebP to re-encode each image through the canvas.
    4. Download a single WebP, or a zip when converting a batch.

    Why convert PNG to WebP?

    WebP was built by Google specifically to make web images smaller, and for most PNGs the savings are substantial. A photographic or richly coloured PNG converted to WebP can drop to a fraction of its original size, which means faster page loads, lower bandwidth bills and quicker sharing. Crucially for PNG users, WebP supports transparency, so you do not have to give up your alpha channel the way you would converting to JPG — a transparent PNG logo becomes a transparent WebP. WebP offers both lossy and lossless modes; this tool uses the quality slider to control lossy encoding, which is where the biggest size wins come from. At high quality settings the difference from the original is very hard to see, while lower settings trade a little sharpness for much smaller files. Keep in mind that flat graphics and simple icons are sometimes already tiny as PNG, so the savings there can be modest, whereas detailed images benefit the most. The one caveat is compatibility: WebP is supported by every current browser but a few older desktop programs still cannot open it. Conversion runs on the HTML canvas inside your browser, so your images are never uploaded, with no signup, watermark or wait.

    FAQ

    Does WebP keep my PNG's transparency?

    Yes. WebP has a full alpha channel, so transparent areas in your PNG stay transparent. This is a key advantage over converting to JPG.

    How much smaller will the WebP be?

    It varies with content. Detailed and photographic PNGs often shrink dramatically, while simple icons that are already small may only shrink a little.

    Is WebP lossy or lossless here?

    This converter uses lossy WebP controlled by the quality slider, which gives the largest size savings. High settings keep the image looking essentially identical.

    Are my PNGs uploaded?

    No. Conversion happens locally in your browser. Your files never leave your device.
