    Higher quality means larger files.

    Smaller files without losing transparency

    PNG is essential for logos, icons and product images because of its transparency support, but the files are large. WebP supports both transparency (an alpha channel) and far more efficient compression, so converting PNG to WebP often halves the size or better while looking the same.

    Where it helps

    • Product images with transparent backgrounds in online shops
    • Website logos, icons and illustrations
    • Mobile app and game UI graphics

    How it works

    Conversion runs in your browser. Transparent pixels are carried over to the WebP file exactly; your image is never uploaded.

    How to use PNG to WebP Converter

    1. Drag your PNG files into the upload area.
    2. Set the quality or keep the default.
    3. WebP files are created with transparency preserved.
    4. Download the results.

    Why use this tool?

    The easiest way to shrink transparent images for the web: no install, no account, and your files stay on your device.

    FAQ

    Does WebP support transparency?

    Yes. Like PNG, WebP supports an alpha channel, so transparent areas stay transparent.

    How much smaller will the file be?

    It depends on the content; photo-like PNGs usually shrink by more than half, simple icons by less.

    Does WordPress accept WebP?

    Yes, WordPress 5.8 and later support WebP uploads natively.
