What Remove empty attrs does in SVGO
SVGO applies removeEmptyAttrs as part of its plugin pipeline. In SVGOMG the toggle is labeled Remove empty 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.
