SVG Optimizer
The SVG Optimizer cleans up an SVG file by removing comments, invisible elements like desc and metadata, editor-specific data from tools like Inkscape, and rounding excessively precise decimal coordinates — without touching the actual visual appearance. This is basic cleanup, not a full replacement for a dedicated tool like SVGO, since it doesn't simplify the path geometry itself. Runs entirely in your browser, with no file ever uploaded to a server.
The optimization happens entirely inside your browser without uploading any SVG to a server.
This is basic cleanup (removing comments, editor metadata, and excess numeric precision) — not a full SVGO-equivalent optimizer, since it does no path-geometry simplification.
What this tool does
Cleans an SVG of what it does not need: comments, editor-specific elements, the XML prolog and any DOCTYPE, plus rounding excessively precise numbers — and reports the size saved.
When to use it
- A logo or icon exported from a design program at an unreasonable size.
- An SVG carrying editor metadata the page has no use for.
- Reducing the size of icons that will be inlined into a web page.
How to use it
- Paste the SVG into the input field.
- Run the optimisation and read the size reduction.
- Copy the output or download it.
A practical example
Input
An icon exported from a design program with comments, editor-specific elements and numbers to ten decimal places.
Output
The same icon visually, noticeably smaller, with everything that does not affect the drawing removed and the numbers rounded.
Limitations
- The optimisation is deliberately basic and is not a replacement for a dedicated optimiser: it does not simplify path geometry or collapse attributes into CSS.
- Check the result visually before relying on it; rounding numbers can slightly alter an extremely precise drawing.
- The saving depends on the file: one exported from an editor saves a lot, one written carefully by hand may save nothing.
Privacy and processing
The optimisation happens entirely inside your browser without uploading any SVG to a server.
Technical notes
- Processing is purely textual and the markup is never handed to a real XML parser — the convention across every XML tool here, to avoid giving untrusted markup to a parser.
- A DOCTYPE is stripped rather than causing the file to be rejected, because a benign one is extremely common in exported SVGs.
Frequently Asked Questions
No — this is basic cleanup that removes comments and invisible metadata and rounds excessively precise numbers, but it doesn't simplify path geometry the way a dedicated tool like SVGO does.
