Free SVG Optimizer & Minifier — No Upload Required

Optimize and minify SVG files online — strip metadata, comments, Inkscape/Figma bloat, and whitespace. Reduce file size up to 60% with no visual changes.

Quick Answer

ZerofyTools SVG Optimizer cleans and compresses SVG files entirely in your browser. It removes XML declarations, comments, empty groups, and editor metadata from Inkscape, Figma, and Illustrator exports — typically reducing file size by 30–60%. Paste your SVG code, configure precision options, compare the before/after visual preview, then copy or download the optimized result. No uploads, no server, no signup.

How do I use the SVG Optimizer & Minifier?

Optimize and minify SVG files online — strip metadata, comments, Inkscape/Figma bloat, and whitespace. Reduce file size up to 60% with no visual changes. This tool runs entirely in your browser — your files and data never leave your device. No registration, no watermarks, no limits.

Paste your SVG source code into the input panel — or click "Load sample" to try it on a real Inkscape export.

Choose optimization options: strip metadata/comments, collapse whitespace, and set float decimal precision (default: 2).

Click ⚡ OPTIMIZE SVG to process instantly in your browser.

Check the before/after visual preview to confirm the output looks identical.

Copy the optimized code to clipboard or click Download to save the cleaned .svg file.

What are the key features of the SVG Optimizer & Minifier?

✓Strips XML declarations, HTML comments, and all editor metadata.
✓Removes Inkscape, Figma, and Illustrator namespace tags (inkscape:, sodipodi:, xlink:).
✓Eliminates empty <g> groups and redundant namespace declarations.
✓Collapses whitespace and newlines for minimal, single-line SVG output.
✓Reduces float precision on path coordinates — configurable 0–6 decimal places.
✓Live before/after visual preview to verify zero visual changes.
✓Real-time file-size display: original KB, optimized KB, and exact % savings.
✓100% client-side — your SVG code never leaves your browser.

What gets removed when you optimize an SVG?

Design tools export SVG files with layers of invisible data that browsers never use. Every item below is safe to remove — none of it affects how the SVG looks or behaves.

Removed element	What it is	Typical source
<?xml … ?>	XML declaration header	All design tools
<!-- comments -->	Developer/editor comments	Inkscape, hand-written SVG
<metadata>…</metadata>	RDF/Dublin Core file info	Inkscape
<title> / <desc>	Accessibility labels (not needed in icon SVGs)	Inkscape, Illustrator
inkscape:, sodipodi:	Inkscape-specific namespace attributes	Inkscape
xlink:, dc:, cc:, rdf:	Legacy and RDF namespace declarations	Inkscape
<g></g> empty groups	Empty layer containers	All tools with layers
Trailing whitespace	Line breaks and indentation	All design tools
High-precision floats	e.g. cx="50.41249013" → cx="50.41"	Figma, Illustrator, Inkscape

How much can you reduce SVG file size?

Savings vary by source tool. Inkscape adds the most bloat; Figma exports are already leaner. These are real-world averages across typical icon and illustration exports.

Inkscape

30 – 60%

Adds XML headers, RDF metadata, and extensive namespace tags

Adobe Illustrator

20 – 45%

Adds AI-specific tags, empty groups, and high-precision floats

Figma (Export)

10 – 30%

Cleaner by default — mainly whitespace and float precision

Hand-written SVG

5 – 20%

Mostly whitespace collapsing and float precision reduction

Which float precision setting should you use?

Float precision reduces the number of decimal places on path coordinates — the biggest source of hidden file weight in complex SVGs.

0Aggressive

Whole numbers only. May visually distort complex curves. Use only for simple geometric shapes.

1Compact

Good balance for simple icons and basic illustrations with straight paths.

2Recommended

Standard setting. Safe for icons, logos, and most illustrations. Negligible visual impact.

3–4Conservative

Preserves fine detail in complex paths. Use for intricate illustrations where precision matters.

Why use this tool and other frequently asked questions?

Will optimizing SVG change how it looks?

No. The optimizer only removes invisible bloat — XML comments, editor metadata, empty groups, and whitespace. All paths, shapes, colors, and visual elements are preserved exactly. The before/after preview lets you confirm this before downloading.

What causes SVG file bloat?

Design tools like Inkscape, Figma, and Adobe Illustrator add extra data to SVG exports: XML declarations, editor-specific namespace tags (inkscape:, sodipodi:), empty layer groups, and high-precision float coordinates on paths. Browsers don't need any of this to render the SVG correctly.

How much can I reduce SVG file size?

Typical savings range from 20% to 60% depending on the source tool. Inkscape exports tend to carry the most bloat (30–60% savings). Figma and manually written SVGs are already leaner (10–30% savings). The optimizer shows the exact KB and percentage saved after every run.

What is float precision and should I change it?

Float precision controls how many decimal places are kept in path coordinate numbers. The default (2) is safe for most icons and illustrations. Reducing to 1 saves a bit more space but may cause barely perceptible rounding on very complex curves. For icons and logos, 2 decimal places is the standard recommendation.

Is this the same as SVGO?

SVGO is the industry-standard open-source library used by most SVG optimizers. ZerofyTools applies the same core optimization rules — strip metadata, remove namespaces, collapse whitespace, reduce float precision — but runs entirely in your browser with no installation, no command line, and no file upload required.
