Quick Tool Overview

The SVG Optimizer strips what a browser never reads — editor namespaces, generator comments, layer names, empty groups — and rounds path coordinates from fifteen decimal places to something a screen can actually resolve. Editor exports commonly drop 40 to 70 percent, with the before and after rendered side by side to prove nothing moved.

About the SVG Optimizer

An SVG exported from Illustrator, Figma or Inkscape carries a lot that a browser never reads: editor namespaces, generator comments, layer names, empty groups and path coordinates written to fifteen decimal places.

Removing all of that typically cuts 40 to 70 percent with no visual change whatsoever. The single biggest win is usually coordinate precision — two decimal places is beyond what any screen can resolve, and dropping to it can halve the file on a complex path. Each transformation can be switched off individually, and the before-and-after preview is drawn so you can confirm nothing moved.

Key features of the SVG Optimizer

Coordinate precision control

The single biggest win on complex paths — two decimals is beyond what any screen resolves and can halve the file.

Visual proof

Before and after are rendered together, so a transformation that broke something is immediately visible.

Each pass is optional

Every removal can be switched off individually, because a file that relies on IDs or a namespace should keep them.

ID removal off by default

CSS, script, gradients and clip paths all reference IDs, so that pass stays off unless you know the file.

Paste or upload

Works from markup on the clipboard as readily as from a file, which is how SVG usually arrives.

How to use the SVG Optimizer

  1. 1

    Add the SVG

    Drop in the file, or paste the markup.

  2. 2

    Choose what to strip

    Metadata, comments, editor attributes and empty groups are safe on almost every file.

  3. 3

    Set the coordinate precision

    Two decimals is plenty for screen use and is where most of the saving comes from.

  4. 4

    Compare and download

    The rendered before and after are shown side by side. Save the optimised markup.

Frequently asked questions

It should not. Everything removed is metadata a renderer ignores. Rounding coordinates is the one lossy step, and at two decimals the difference is far below one pixel.
