SVG Minifier
Quick Answer
It reduces file size by stripping whitespace, comments, metadata, and redundant attributes, and optimising path data — without changing the visual output.
What Is SVG Minifier?
SVG Minifier is a free online image & media tool that minify svg code by removing unnecessary whitespace, comments and attributes. An SVG minifier reduces the file size of an SVG by removing unnecessary whitespace, comments, metadata, and redundant attributes. It also optimises path data by rounding decimal places and removing unused definitions. Smaller SVG files mean faster page loads and lower bandwidth usage — especially important for icon sets and illustrations used repeatedly across a site. The tool lets you paste raw SVG markup or upload an SVG file. It shows a before/after size comparison and the percentage reduction. The optimised SVG is visually identical to the original; only non-essential data is stripped. All processing runs in your browser. Unlike many similar tools, it runs entirely in your browser — no data is sent to any server, no account is required, and there are no usage limits. Whether you are a developer, writer, SEO professional, or casual user, this tool provides instant, accurate results without friction.
