The optimization runs locally, so your markup is never uploaded.
What gets removed
Editor comments, metadata blocks and unused namespaces are stripped, since browsers ignore them anyway. Extra whitespace between tags is collapsed.
Long coordinate numbers are rounded to a sensible precision, which alone can cut a noticeable share of the file size on detailed paths.
How to use it
Drop in an SVG and the cleaned version appears next to the original with the size saving shown as a percentage.
Download the optimized file, or paste the result into your codebase. The visual output stays identical to the source.
Why smaller SVGs matter
On the web, every kilobyte of markup is parsed on the main thread, so trimmer icons and illustrations help a page become interactive sooner.
Lean SVGs also read better when they live inline in your components, keeping your source files easier to scan and maintain.
Frequently asked questions
Will compression change how the SVG looks?
No. Only data that does not affect rendering is removed, and coordinates are rounded within a safe precision.
Can it break my animations or scripts?
Inline styles and IDs are preserved, so most animations survive. Always keep your original file as a backup before replacing it.
How much smaller will my file be?
It depends on the source. Files exported from design apps often shrink by a third or more, while already tidy SVGs change very little.
Does it work on hand written SVG?
Yes, though a carefully authored SVG has less to remove, so the savings are usually modest.
