    Usage statistics

    We count page views and operations. A random cookie identifies a browser profile; after sign-in its activity is linked to your account. Your last IP and its observation date are visible only to the site owner and kept for up to 90 days. Daily counts are kept for 90 days, and inactive profiles are removed after 90 days. Formats, outcomes, error codes, and size and time ranges are counted separately. File names, contents and metadata stay on your device. Turning this off deletes the current browser profile.

    How to convert PNG to AVIF

    1. Click the box above or drag your PNG files onto it — you can add many at once.
    2. Wait a bit: AVIF encoding happens in your browser and takes longer than JPG or WebP.
    3. Download each AVIF separately or grab them all in one ZIP file.

    Why use this converter

    • Your files stay with you

      Everything runs on your device. Images are never uploaded to a server, so nobody else ever sees them.

    • Transparency is kept

      AVIF supports transparency, so a transparent PNG background stays transparent.

    • Several times lighter

      PNG stores images losslessly, while AVIF uses lossy compression — photos and complex images usually get several times smaller.

    • Batch conversion

      Convert up to 100 images at a time and download them as a single ZIP file.

    Frequently asked questions

    What is AVIF?

    AVIF is a modern image format based on the AV1 video codec. Every modern browser supports it, which makes it great for websites: pages load faster.

    Is transparency preserved?

    Yes. AVIF stores an alpha channel, so transparent areas of the PNG stay transparent.

    Is AVIF good for screenshots and logos?

    For photos and complex illustrations, yes. Screenshots with small text and logos with sharp edges may show visible artifacts with lossy compression — keep those as PNG or raise the quality.

    Why does encoding take so long?

    The AV1 encoder works hard to find the best way to compress every part of the image. In the browser it runs on a single thread, so a large image can take tens of seconds.

    Which quality should I choose?

    The default of 75 is usually indistinguishable from the original on photos. Raise it for images with text and thin lines.

    Is it safe to convert my images here?

    Yes. The site only downloads the converter itself; your images are processed in your browser and are never sent to a server.
