About SVG Optimizer

Toolium's SVG Optimizer Studio dramatically shrinks vector graphics by removing non-rendering editor metadata, XML comments, DOCTYPE declarations, unnecessary spaces, and reducing coordinate floating-point precision. With side-by-side visual and code diffing, you can ensure 100% visual fidelity while achieving up to 70%+ file size reduction for ultra-fast web and mobile load times.

How to use SVG Optimizer

  1. Paste SVG code or upload an SVG file.
  2. Choose the options, such as removing comments and metadata and reducing precision.
  3. Compare the preview of the original and the optimized version.
  4. Copy or download the smaller SVG.

Worked examples

Input: An SVG exported from a design tool with editor metadata and long decimal coordinates

Result: A markedly smaller file, often by tens of percent, that renders identically.

Background

SVG files exported from design tools often contain editor metadata, comments, empty groups and coordinates with many decimal places. None of these affect the final picture.

Reducing coordinate precision is the one lossy step. Two decimal places is usually invisible, but extreme rounding can distort curves in small icons. Always compare the preview before replacing your original file.

Common mistakes

  • Rounding coordinates so far that curves visibly change.
  • Removing the viewBox attribute, which breaks scaling.
  • Replacing the original file without checking the preview.

Frequently Asked Questions

Will optimizing my SVG alter its visual appearance?
No — the optimization passes remove redundant non-rendering tags, metadata, comments, and collapse whitespace while preserving all visual paths, fills, and strokes.
Which profile should I choose?
We recommend 'Balanced Web' for standard web icon and asset usage. It strips editor bloat and rounds coordinates to 2 decimal places for significant savings.
Is my SVG processed on a server?
Never. All parsing and optimization executes 100% inside your browser using client-side Web APIs.
