Select AVIF images to compress, several at once

Images are compressed in memory on our server and sent straight back. Nothing is stored.

Compress AVIF images and keep them AVIF

AVIF is one of the most efficient image formats there is, so an AVIF compressor has less to win than a JPG compressor has. It still helps when a file was exported at a high quality: the image is re-encoded at the Quality you pick and saved as an AVIF again, with the same width and height.

Drop several files at once, up to 40 MB each. Camera EXIF data is removed and the colour profile is kept. If an AVIF cannot get smaller, the original comes back unchanged.

What decides how small an AVIF gets

  • The Quality slider

    It runs from 10 to 100. The lower you set it, the smaller the file and the softer the detail.

  • How it was saved

    An AVIF exported at a high quality has the most to lose. One already saved at a low quality may come back unchanged.

  • The picture itself

    Smooth skies and flat areas shrink easily. Fine textures and noise hold on to their bytes.

AVIF supports lossy and lossless compression, HDR and transparency, and current versions of Chrome, Edge, Firefox and Safari show it. Lossy compression leaves traces that get easier to see as you lower the slider; image compression artifacts shows what to look for.

When another format or tool fits better

  • Your case

    You need a JPG that opens everywhere.

    What to use

    There is no AVIF to JPG tool on this page. The image converter on the converters page changes the format, and the JPG compressor then shrinks the result.

  • Your case

    You have AVIF, WebP, JPG and PNG files together.

    What to use

    The image compressor takes mixed formats in one batch.

  • Your case

    You also have WebP files.

    What to use

    The WebP compressor shrinks them the same way, with a Quality slider or a Lossless option. Smaller images also help a page load sooner, as faster website, faster loading explains.

How to compress an AVIF

  1. Drop your AVIF files

    Add one or several AVIF images, up to 40 MB each.

  2. Set Quality

    Lower the Quality slider for a smaller file and raise it to keep more detail.

  3. Compress and download

    Click Compress AVIF, check the size before and after for each file, and download them.

AVIF compressor questions

AVIF is already very efficient, so the saving is usually smaller than on a JPG. Lower the Quality slider for more; a file that cannot shrink comes back unchanged.

Yes. The result is an AVIF with the same width and height as the original.

It is re-encoded at the Quality you set, so lowering the slider removes some detail. Keep a copy of the original if you may need the full quality later.

No, this page only takes AVIF and returns AVIF. Use the image converter on the converters page to change the format.

Camera EXIF data is removed, which also saves a little space. The colour profile is kept so the colours look the same.
