Preset Default

SVGO runs with a default preset that has the plugin ID preset-default. This is the default set of plugins that are used when not explicitly specified or overridden elsewhere.

info

If you aren't using SVGO directly, like through SVGR, the default plugins may be different from the default preset.

Disable a Plugin

Sometimes a specific plugin might not be appropriate for your workflow. You can continue using preset-default while disabling any plugin by using the overrides parameter.

In overrides, reference the plugin ID and set it to false to disable it:

module.exports = {
  plugins: [
    {
      name: 'preset-default',
      params: {
        overrides: {
          removeViewBox: false,
        },
      },
    },
  ],
};

Alternatively, you can also drop default-preset entirely, and configure your own plugin pipeline from scratch, with only the desirable plugins:

module.exports = {
  plugins: [
    'removeDoctype',
    'removeXMLProcInst',
    'minifyStyles',
    'sortAttrs',
    'sortDefsChildren',
  ],
};
