Remove xmlns (removeXMLNS)
Removes redundant default xmlns attributes when they can be inferred, shrinking attribute noise.
What Remove xmlns does in SVGO
SVGO applies removeXMLNS as part of its plugin pipeline. In SVGOMG the toggle is labeled Remove xmlns (off by default). Optimization runs entirely in your browser — files are not uploaded to a server.
Use the SVGOMG optimizer with Show original to compare before and after. If output looks wrong, disable this plugin first, then re-enable related transforms one at a time.
When to enable
Standalone SVG files embedded where the namespace is implicit.
When to disable
SVGs used as documents, mixed namespaces, or fragments that rely on explicit xmlns.
Watch out for
Can break unusual namespace setups; off by default in SVGOMG.
Try it in SVGOMG
- Open svgomg.net and load your SVG (file, paste, or demo).
- Find Remove xmlns in the Features panel (
removeXMLNS). - Toggle the plugin and compare the preview; download when satisfied.
