    The details

    What happens when you convert between document formats

    The next generation of image compression. The best quality per byte available today. The document is opened in a layout engine and re-saved in the target format, mapping each style onto the closest equivalent in the new format. The result is a the modern web image format. smaller than jpg at the same quality, with transparency like png, produced entirely inside your browser.

    What survives

    • The text and the paragraph structure
    • Most formatting: fonts, sizes, colours, alignment, lists and tables
    • Embedded images

    What changes

    • Styles that have no equivalent are approximated
    • The file may gain or lose features the target format does not support

    Where it goes wrong

    • Styles are usually mapped by name, so renaming a style before converting can lose the mapping
    • The target format may not support the same page size or margins

    Why anyone would do this

    Different teams use different formats, and the content should not be held hostage by that.

    About the format

    The next generation of image compression.

    An AV1-based still image inside the AVIF container, with the same flexible item structure as HEIF.

    Where it is good
    • Around 30–50% smaller than WEBP at the same quality
    • Full HDR and alpha support
    • A single encoder handles animation too
    Where it falls short
    • Encoding is slow and CPU-heavy
    • Older browsers and most desktop image viewers still cannot open it
    • Very few upload forms accept it
    You will find it on
    Performance-focused web teams, modern design tools

    The thing people miss

    AVIF is often smaller than the JPG it was converted from at a *higher* quality setting.

    About the target

    The modern web image format.

    A container for VP8, VP8L or AV1 compressed image data, optionally with animation. Google designed it specifically for the web.

    • Roughly 30% smaller than JPG at the same perceived quality
    • Supports both lossy and lossless, plus transparency and animation
    • Supported by every current browser
