SVGO
SVG Optimizer is a Nodejs-based tool for optimizing SVG vector graphics files.
Why?
SVG files, especially exported from various editors, usually contains a lot of redundant and useless information such as editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting SVG rendering result.
What it can do
SVGO has a plugin-based architecture, so almost every optimization is a separate plugin.
Today we have:
- [ cleanupAttrs ] cleanup attributes from newlines, trailing and repeating spaces
- [ removeDoctype ] remove doctype declaration
- [ removeXMLProcInst ] remove XML processing instructions
- [ removeComments ] remove comments
- [ removeMetadata ] remove
<metadata>
- [ removeTitle ] remove
<title>
(disabled by default) - [ removeDesc ] remove
<desc>
(only non-meaningful by default) - [ removeUselessDefs ] remove elements of
<defs>
withoutid
- [ removeEditorsNSData ] remove editors namespaces, elements and attributes
- [ removeEmptyAttrs ] remove empty attributes
- [ removeHiddenElems ] remove hidden elements
- [ removeEmptyText ] remove empty Text elements
- [ removeEmptyContainers ] remove empty Container elements
- [ removeViewBox ] remove
viewBox
attribute when possible (disabled by default) - [ cleanUpEnableBackground ] remove or cleanup
enable-background
attribute when possible - [ convertTyleToAttrs ] convert styles into attributes
- [ convertColors ] convert colors (from
rgb()
to#rrggbb
, from#rrggbb
to#rgb
) - [ convertPathData ] convert Path data to relative or absolute whichever is shorter, convert one segment to another, trim useless delimiters, smart rounding and much more
- [ convertTransform ] collapse multiple transforms into one, convert matrices to the short aliases and much more
- [ removeUnknownsAndDefaults ] remove unknown elements content and attributes, remove attrs with default values
- [ removeNonInheritableGroupAttrs ] remove non-inheritable group's "presentation" attributes
- [ removeUselessStrokeAndFill ] remove useless stroke and fill attrs
- [ removeUnusedNS ] remove unused namespaces declaration
- [ cleanupIDs ] remove unused and minify used IDs
- [ cleanupNumericValues ] round numeric values to the fixed precision, remove default 'px' units
- [ moveElemsAttrsToGroup ] move elements attributes to the existing group wrapper
- [ moveGroupAttrsToElems ] move some group attributes to the content elements
- [ collapseGroups ] collapse useless groups
- [ removeRasterImages ] remove raster images (disabled by default)
- [ mergePaths ] merge multiple Paths into one
- [ convertShapeToPath ] convert some basic shapes to path
- [ sortAttrs ] sort element attributes for epic readability (disabled by default)
- [ transformsWithOnePath ] apply transforms, crop by real width, center vertical alignment and resize SVG with one Path inside (disabled by default)
- [ removeDimensions ] remove width/height attributes if viewBox is present (disabled by default)
- [ removeAttrs ] remove attributes by pattern (disabled by default)
- [ addClassesToSVGElement ] add classnames to an outer
<svg>
element (disabled by default)
