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. On SVGOMG.net the toggle is labeled Sort attrs (enabled by default). Optimization runs entirely in your browser — files are not uploaded to a server.

Use SVGOMG.net 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).

Watch out for

Try it

Open SVGOMG.net and load your SVG (file, paste, or demo).
