Minify SVG Online — Remove Whitespace & Metadata
Minify SVG instantly — select, reorder, concatenate and minify multiple .svg files as one bundle with your current options. Strip unnecessary whitespace and metadata elements while everything stays in your browser. For SVGO deep optimization, use our optimize SVG tool.
Features
Remove unnecessary whitespace, comments, metadata elements and optional hidden style elements from SVG files while preserving visual quality.

What SVG minification does
SVG minification on this page is a light markup cleanup that keeps the graphic. Comments can go. Space between tags is collapsed. Extra spaces in text runs can be squeezed. The <metadata> element can be dropped. Empty attributes like id="" can be removed. Elements whose style is display:none or visibility:hidden can be stripped if you turn that option on. Accessibility tags <title> and <desc> stay. So do viewBox, element IDs, and the numbers inside path d.
The output is still SVG source, not a zip. Gzip and Brotli are a later layer on the wire — this tool does not gzip your file.
This page is not an SVG optimizer. It does not rewrite path data, round coordinates, change IDs, convert styles to attributes, or prune unused <defs>. Those structural edits are SVGO's job. Use this pass when you want fast whitespace-and-comment cleanup, for example before pasting an icon inline. For path rewrite and editor-namespace cleanup, continue on the complementary optimize SVG tool.
How FastMinify minifies SVG
FastMinify minifies SVG with an in-tab regex pipeline. SVGO is not loaded on this page, so the tab stays light.
Two cleanups always run: whitespace between tags becomes ><, and spaces around = are removed. The Collapse whitespace switch is separate — when on (the default), remaining runs of spaces collapse to one. Turning it off does not put newlines back between tags.
Remove comments (default on) drops <!-- ... -->. Remove metadata (default on) deletes <metadata>...</metadata> only — not editor namespaces. <title> and <desc> are kept. Remove empty attributes (default off) drops attr="". Remove hidden elements (default off) matches only style values display:none or visibility:hidden, not display="none" as an attribute, hidden, or opacity="0". Path d, IDs, and viewBox are left as pasted.

Developer notes
• This page removes whitespace, comments and <metadata> elements without loading SVGO (~780 KB).
• Toggle options before you minify — all processing stays in-tab.
• For path rewrite and SVGO presets, switch to optimize SVG after this pass.
• Pair with validate SVG for viewBox or title/desc checks.
When teams pick this route
• Strip whitespace from icons pasted into HTML or React components before commit. • First cleanup pass on Figma/Illustrator exports before deeper SVGO optimization. • Compress sprite candidates when you only need comment and space removal. • Use beautify SVG or unminify SVG to inspect markup, then return here for production minify.
SVG cluster tools
This page is the light minify step. For SVGO presets and the rest of the SVG cluster, open the SVG tools hub or the complementary optimize SVG tool.
Concatenating SVG Files
On Minify SVG, select or drop multiple .svg files, reorder them, then concatenate and minify the complete bundle once with your current options. Processing stays in your browser. Files are joined with newline boundaries only — no HTML comment markers inside SVG markup. This workflow batches separate icon files for minification; it does not build sprite sheets. For single-file SVGO optimization, use optimize SVG.
Frequently Asked Questions — Minify
Everything about minification
Why minify SVG?
SVG minification removes whitespace, comments and <metadata> elements to reduce file size. It does not gzip the file or rewrite paths.
Need to unminify SVG?
Use our SVG unminifier to inspect compressed markup.
Need to beautify SVG?
Use our SVG beautifier for readable SVG formatting.
Need deeper SVGO optimization?
Use optimize SVG for SVGO safe, default and aggressive presets.
How do I concatenate and minify multiple SVG files?
On Minify SVG, use the concat button or drop two or more .svg files on the input panel, reorder them, then concatenate and minify the complete bundle once with your current options. Everything runs in your browser. This workflow is not available on Beautify SVG or Unminify SVG. Files are joined with newline boundaries only — this batches separate icons for minification, not sprite sheet generation. For single-file SVGO optimization, use optimize SVG.
