SVG Optimizer & Minifier

Clean bloated editor metadata, round path coordinate precision, and compress SVG vector graphics instantly in your browser.

At a glance

SVG Optimizer & Minifier is a free, client-side tool that compresses, cleans, and minifies SVG files online. It strips XML declarations, doctypes, block comments, and editor namespaces from Adobe Illustrator, Inkscape, Sketch, and Figma. Nothing is uploaded and no sign-up is needed — everything runs on your device.

Why Use This SVG Optimizer & Minifier?

XML Cruft & Metadata Removal: Strips XML declarations, doctypes, block comments, and editor namespaces from Adobe Illustrator, Inkscape, Sketch, and Figma.
Coordinate & Numeric Precision Rounding: Configurable decimal precision (1, 2, or 3 decimals) to eliminate excessive floating-point bloat in paths, shapes, and transforms.
Intelligent Path Compression: Collapses redundant spaces and delimiters between path commands and removes leading zeros while preserving sub-pixel visual fidelity.
ViewBox & Scalability Enforcement: Preserves viewBox and automatically synthesizes responsive viewBox attributes if missing from fixed width and height dimensions.
Dual Output Modes: Choose between single-line production Minified mode and clean 2-space indented Pretty Print mode for human code inspection.
Live Visual Comparison & Telemetry: Interactive transparency checkerboard preview to confirm zero visual degradation, paired with real-time byte savings telemetry.

How to Use SVG Optimizer & Minifier

1

Upload or Paste Your SVG Code

Drag and drop an .svg file into the editor or paste raw SVG XML markup exported from Figma, Illustrator, or Inkscape.

2

Configure Optimization & Precision

Choose your desired coordinate decimal precision (1, 2, or 3 decimals) and output format (single-line Minified or formatted Pretty Print).

3

Verify and Download Clean SVG

Visually verify the rendered vector on the checkerboard preview to confirm identical quality, then copy the clean markup or download your optimized .svg file.

Frequently Asked Questions

How much file size reduction can I expect from SVG optimization?
Depending on the authoring tool, SVGs exported from Figma, Illustrator, or Inkscape frequently shrink by 40% to 75%. Removing editor comments, metadata, unused namespaces, and rounding excessive coordinate decimals eliminates substantial bloat.
Will optimizing an SVG change its visual appearance or sharpness?
No. Our optimizer preserves path geometries and curves. Coordinate precision rounding to 2 decimal places keeps path points accurate to sub-pixel fractions while drastically reducing file byte size.
Does the optimizer preserve the viewBox attribute?
Yes. Preserving viewBox is critical for responsive web layouts and CSS scaling. If an input SVG lacks a viewBox but provides width and height attributes, the optimizer automatically generates a matching viewBox for scalable rendering.
Are my vector illustrations uploaded to an external server?
No. All XML parsing, regex stripping, and coordinate precision optimizations execute entirely within your browser using client-side JavaScript. Your graphics, logos, and vector art never leave your computer.
