svg-strip

Fast and aggressive SVG minification CLI tool built in Rust, tailored specifically for shrinking SVGs for inline HTML use (like Blade templates) and standalone files.

Features

• Extreme Minification (automatic): Removes title, desc, metadata, comments, unused ids, hidden elements (display="none", opacity="0"), empty groups, and the <?xml...?> declaration, collapsing all whitespace and linebreaks into a single-line string.
• Color Shrink (automatic): Identifies 6-digit hex color codes with identical byte pairs (e.g., #FF0000, #aabbcc) across all styling attributes (fill, stroke, etc.) and losslessly converts them into their 3-digit shorthands (e.g., #f00, #abc). Leaves non-matching hex codes safely untouched.
• Inline Optimization (-i / --inline): Strips the xmlns attributes which are unnecessary overhead for browsers when embedding SVGs directly into HTML5 code.
• Decimal Precision (-dp / --decimal-precision): Aggressively rounds all path coordinates and attributes (like viewBox, x, y, transform) down to a user-specified number of decimal places (0-4), stripping trailing zeros.

Usage

svg-strip [OPTIONS] <input.svg> [output.svg]

If no output.svg is specified, the tool will automatically save the minified file in the same directory as [ORIGINAL_NAME]_stripped.svg.

Options

Flag	Name	Description
-i, --inline	Inline Mode	Strips xmlns attributes for optimal inline HTML usage.
-o, --output	Stdout Mode	Prints the minified SVG directly to the terminal (stdout) instead of writing to a file.
-dp, --decimal-precision <0-4>	Decimal Precision	Rounds all floating point numbers inside paths and attributes to the specified number of decimal places to save bytes.

Example

Minify an icon for use in a web template, stripping all namespace overhead and rounding coordinates to 2 decimal places:

svg-strip -i -dp 2 raw_icon.svg

Output:

Stripped SVG written to raw_icon_stripped.svg
• Inline SVG with zero overhead
• Decimal Precision for paths rounded down to 2 decimals
• Color Shrink to convert 6-digit hex codes to 3-digit shorthands
