svgcleaner build status

svgcleaner helps you clean up your SVG files, keeping them free from unnecessary data.

Table of Contents


The main purpose of svgcleaner is to losslessly reduce the size of an SVG image, created in a vector editing application, before publishing.

Usually more than half of an SVG image's data is useless for rendering. For example:

  • Temporary data used by the vector editing application
  • Non-optimal SVG structure representation
  • Unused and invisible graphical elements

... Are all unnecessary in a published SVG.


  1. Correctness - svgcleaner should not break an SVG file
  2. Cleaning ratio - Higher is better
  3. Performance - An average SVG file processing time should be closer to ~1ms on a modern PC


In addition to the main advantages of svgcleaner — like correctness, cleaning ratio and performance, which are described below — there are some more nuances to be aware of:

  1. svgcleaner cleans only one SVG file. It doesn't process SVGZ files. It doesn't process directories. It doesn't do anything else. Just one task*.
  2. svgcleaner is strictly lossless by default. There are no destructive cleaning options enabled by default.
  3. svgcleaner is portable. You can build it into a single executable without any external dependencies.

* You can get all of these features using the GUI.


See Testing notes for details.

svgcleaner shouldn't change your file unless you tell it to, but there are still things that can't be preserved. So even if you disable all cleaning options there are still things that will be changed, such as:

  • Original indent is not preserved
  • All colors will be formatted as #RRGGBB and #RGB
  • DOCTYPE, CDATA will be processed and removed
  • CSS support is minimal
  • CSS from the style element will be extracted and processes. The style element will be removed.
  • The style attribute will be split into attributes
  • The class attribute will be processed and removed
  • Paths and transformations will be reformatted
  • currentColor and inherit attributes values will be resolved
  • Referenced elements will be moved to the defs element
  • IRI and FuncIRI attributes that reference non-existing objects will be removed
  • If the offset attribute value of the stop element is represented as percentage - it will be converted into a decimal number
