Sort attrs (sortAttrs)
Sorts attributes alphabetically for better gzip compression and consistent diffs.
What Sort attrs does in SVGO
SVGO applies sortAttrs as part of its plugin pipeline. In SVGOMG the toggle is labeled Sort attrs (enabled 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
Production assets served with compression; teams caring about VCS diffs.
When to disable
When attribute order is relied on by non-standard parsers (rare).
