Minify & Optimize SVG for Production (1‑click + best practices) in IconVectors

Minify and optimize SVG icons for production

Production SVGs should be tiny, robust, and themable. In this guide you’ll learn the 1‑click Minified export in Axialis IconVectors and when to run SVGO on top for advanced cases. The page structure and SEO mirror your recent tutorials for consistency.

Why minify SVGs?

Step‑by‑step in IconVectors

  1. Open, draw, or import your SVG icon.
    • Open existing SVG: File → Open… (Ctrl+O)
    • Create from scratch: New Icon (Ctrl+N)
    Preparing an icon in IconVectors on a 24×24 grid
    Design on a consistent grid; verify attributes with View → Source Code (F3).
  2. Export a minified SVG — choose File → Export → Export Minified (Shift+Ctrl+M). This strips unnecessary whitespace/metadata and writes a compact, production‑ready file. You can confirm the result in the read‑only code viewer (F3).
  3. Best‑practice checklist (what your minified SVG should keep)
    • Keep viewBox for proper scaling (e.g., viewBox="0 0 24 24").
    • Use currentColor for fills/strokes so the icon can be themed via CSS.
    • Prefer simple paths (boolean ops done in editor) and snap to whole‑pixel coordinates for crisp small sizes.
    <!-- Good: compact, themable, scalable -->
    <svg viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
      <path d="M4 12l4 4 12-12" fill="none" stroke="currentColor" stroke-width="2"/>
    </svg>
  4. When to still run SVGO

    IconVectors’ Minified export is usually enough. Run SVGO in a build step when you need stricter control (e.g., unified precision, ID prefixing, enforcing removeViewBox:false, removing dimensions for responsive sizing).

    Install (once per project):

    npm i -D svgo
    # or ad‑hoc:
    npx svgo --version

    Minimal svgo.config.js (safe defaults):

    module.exports = {
      multipass: true,
      plugins: [
        {
          name: 'preset-default',
          params: {
            overrides: {
              // Keep scaling behavior predictable
              removeViewBox: false,
              // Keep IDs stable unless you need prefixing:
              cleanupIDs: { minify: true }
            }
          }
        },
        // Optional: make SVGs responsive by dropping width/height
        'removeDimensions'
      ]
    };

    Run on a folder:

    # Optimize all SVGs in ./icons to ./dist/icons
    npx svgo -f icons -o dist/icons

    Before → After (typical):

    - <svg width="24" height="24" viewBox="0 0 24 24">
    -   <path fill="#000000" d="M4 12 L8 16 L20 4" />
    -   <!-- metadata, comments, unused groups... -->
    - </svg>
    + <svg viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
    +   <path d="M4 12 8 16 20 4" fill="none" stroke="currentColor" stroke-width="2"/>
    + </svg>
  5. Validate quickly
    • Open the file with F3 to confirm viewBox, currentColor, and compact path data.
    • Use a sprite or inline in HTML to confirm theming; avoid <img src="…"> if you need CSS color inheritance.
