SVG Optimizer
Strip comments, redundant attributes, and extra whitespace from SVG markup, with a before/after visual preview and file size comparison.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
How the SVG optimizer works
- Paste SVG markup or upload an .svg file.
- The tool strips comments, the XML declaration, empty design-tool artifacts, redundant attributes, and extra whitespace.
- Compare the before/after preview and file size, then copy or download the optimized result.
FAQ
What does the optimizer actually remove?
Comments, the XML declaration, empty title/desc tags left behind by design tools, redundant default attributes (like version="1.1" and stroke="none"), an unused xlink namespace, and extra whitespace between tags — all of which shrink file size without changing how the SVG renders.
Will this ever break my SVG's appearance?
It's designed not to — every removed piece is either purely cosmetic in the source (comments, whitespace) or an attribute already equal to the SVG spec's default value (stroke="none" is the default stroke, so stating it explicitly and removing it render identically). Always check the before/after preview to confirm nothing changed.
Is this the same as SVGO?
No — SVGO is a much more thorough, industry-standard optimizer with dozens of configurable passes (path simplification, precision rounding, and more). This tool covers the most common, safe wins in a lightweight way that runs entirely in your browser.
Is my SVG uploaded anywhere?
No. Optimization happens entirely in your browser as you type — nothing is sent to Online Tool Store or any other server.
