    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 JPG to AVIF

    1. Click the box above or drag your JPG files onto it — you can add many at once.

    Why use this converter

    • Your files stay with you

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

    • Lighter at the same quality

      AVIF is based on the AV1 video codec and usually compresses photos better than JPG. Each file's row shows the size before and after.

    • Colors and metadata

      The color profile is copied into the AVIF. By default the capture date is kept and the location is removed.

    • 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.

    How much smaller is AVIF than JPG?

    It depends on the photo and the quality you pick. AVIF is usually noticeably lighter than JPG at similar quality, though an already heavily compressed JPG may shrink less. Each file's row shows the size before and after.

    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 photo can take tens of seconds. In return, everything stays on your device.

    Which quality should I choose?

    The default of 75 is usually indistinguishable from the original on photos. Go lower for thumbnails and backgrounds, higher for very detailed shots.

    Will AVIF open on my computer?

    Modern browsers and many apps open AVIF, including the Photos app on Windows 11 and Preview on macOS. For older software, JPG is the safer choice.

    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.
