SVG Optimizer

Reduce SVG File Size Without Losing Quality

Paste or drop your SVG markup to remove comments, editor metadata, whitespace, and redundant attributes. Choose a compression level based on how much information you want to strip. The optimized SVG is ready to copy or download immediately.

How to Use the SVG Optimizer

Drop an SVG file onto the drop zone, click it to browse, or paste SVG markup directly into the text area.
Choose an optimization level: Gentle, Balanced, or Aggressive.
Results appear immediately — review the original size, optimized size, bytes saved, and reduction percentage.
Copy the output or download it as optimized.svg.

What SVG Optimization Removes

SVG files exported from design tools (Illustrator, Figma, Inkscape) typically contain significant overhead: XML comments, editor-specific namespaces, unused <defs> blocks, empty elements, redundant group wrappers, and verbose attribute formatting. None of this affects how the SVG renders in a browser.

Common removals:

XML declarations (<?xml version="1.0"?>)

Inkscape/Sodipodi/Adobe namespaces and metadata elements (<metadata>, <sodipodi:*>, <inkscape:*>)
Empty <g> groups with no meaningful attributes
id attributes not referenced elsewhere
Default attribute values (e.g., fill-opacity="1", stroke="none")
Unnecessary whitespace inside path d attributes and between elements

Optimization Levels

Gentle: removes XML declaration, comments, and obvious editor metadata. Safe for any SVG — preserves all IDs, classes, and attributes. Good for SVGs used in CSS animations or JavaScript manipulation.
Balanced: also removes empty groups, whitespace between elements, unreferenced IDs, and default attribute values. Recommended for most static icons and illustrations.
Aggressive: also collapses numeric precision in path coordinates (4+ decimal places → 2), removes <title> and <desc> elements, and merges redundant transforms. May slightly affect precision in complex technical drawings.

When Not to Optimize Aggressively

Aggressive optimization can cause problems in specific cases:

SVGs used with CSS selectors targeting specific IDs or classes — removing IDs breaks the selector
SVGs embedded in animation libraries that reference element IDs
Technical diagrams where sub-pixel coordinate precision matters
SVGs with <title> used for accessibility (screen readers)

Use Gentle or Balanced for SVGs that are part of interactive or accessible UI.
