Browsers: Chrome, Firefox, Safari, Edge.

Applications: Illustrator, Inkscape, Figma, Affinity Designer.

Advantages of SVG

  • Resolution independent
  • Tiny files for icons and logos
  • Styleable and animatable with CSS

Limitations to know about

  • Unsuitable for photographs
  • Can embed scripts, so untrusted SVGs need sanitising

When to use SVG

  • Logos
  • Icons
  • Charts and diagrams

Convert SVG files

Rasterising an SVG fixes its resolution — choose the largest size you will ever display before converting.

What SVG is recommended for

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

  • Transparency100/100

    • Because it supports transparency.

  • Animation100/100

    • Because it stores multiple frames, so animation is supported natively.

  • Browser compatibility100/100

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

  • Operating system compatibility100/100

    • Because Windows, macOS, Linux, Android and iOS all open it without extra software.
    • Because most platforms handle it natively.

  • Software compatibility100/100

    • Because a broad range of applications read and write it.
    • Because several mainstream applications support it.

  • 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.

  • AI compatibility100/100

    • Because open specifications are implemented by the open-source decoders that ML stacks rely on.
    • Because lossless pixels avoid compression artefacts leaking into training data.
    • Because wide library support means common data loaders can read it.

  • Long-term archiving100/100

    • Because the specification is public, so a decoder can always be rebuilt.
    • Because lossless storage preserves the original data for future migrations.
    • Because it is a current, actively maintained format.

  • Professional editing100/100

    • Because lossless data survives repeated open-edit-save cycles without degrading.
    • Because professional applications read and write it.

  • Open standards100/100

    • Because the specification is published openly.
    • Because an official specification document is publicly reachable.

  • Licensing100/100

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

  • Popularity100/100

    • Because it sits at the centre of the format ecosystem, with many documented relationships.
    • Because mainstream applications ship support for it.
    • Because every mainstream operating system handles it.

  • 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.

  • Everyday consumer usage75/100

    • Because it opens by double-clicking on every mainstream device.
    • Because it is a current format that people and services still expect.

  • Printing suitability71/100

    • Because lossless data means no compression artefacts appear at print resolution.

What SVG is not recommended for

  • Compression efficiency0/100

    • Because it stores data losslessly, so files stay large.
    • Because its codec generation predates modern entropy coding and block partitioning.
