What OGG is recommended for

Every conclusion below is derived from the structured facts on this page — nothing is written by hand.

  • Browser compatibility100/100

    • Because every major browser engine renders it natively.
    • Because at least one shipping browser renders it.

  • Web suitability100/100

    • Because browsers render it natively, so no conversion step is needed at request time.
    • Because lossy compression keeps transfer sizes and Core Web Vitals in check.
    • Because the specification is open, so tooling and CDNs implement it freely.

  • Cloud compatibility100/100

    • Because an open specification means cloud SDKs can implement it without licensing friction.
    • Because it converts into many other formats, which suits automated pipelines.

  • Streaming100/100

    • Because lossy compression keeps the bitrate low enough to stream reliably.
    • Because browsers decode it natively, so it plays without a plugin.
    • Because open specifications avoid per-stream licensing complications.

  • Open standards100/100

    • Because the specification is published openly.

  • Licensing100/100

    • Because an openly specified format can be implemented without a licence negotiation.
    • Because the core patents are old enough to have expired.

  • Decode performance100/100

    • Because smaller payloads mean less I/O and faster first paint.
    • Because mature formats benefit from hardware and SIMD-optimised decoders.

  • Future-proofing88/100

    • Because it is actively maintained and current.
    • Because open specifications outlive the companies that create them.
    • Because nothing in the graph supersedes it yet.

  • Long-term archiving76/100

    • Because the specification is public, so a decoder can always be rebuilt.
    • Because it is a current, actively maintained format.
    • Because it has a decade or more of proven, stable implementations.

  • Compression efficiency69/100

    • Because it compresses lossily, which produces much smaller files than lossless coding.
    • Because it defines a documented compression scheme.

What OGG is not recommended for

  • Printing suitability0/100

    • Because lossy artefacts become visible when the image is enlarged for print.
    • Because it does not satisfy: it is a page-description format built around fixed layout.

  • Professional editing0/100

    • Because each edit-and-save cycle compounds compression damage.
    • Because it does not satisfy: professional applications read and write it.

  • Operating system compatibility33/100

    • Because at least one mainstream platform needs extra software.

  • Software compatibility33/100

    • Because only a narrow set of applications handles it.
