What is SVG Compression?

Removing unnecessary code from XML structure

SVG compression (also called optimization or minification) reduces SVG file size by removing unnecessary code from the XML structure. Unlike raster images (JPG, PNG), SVGs are text files containing XML code that describes shapes, paths, and styles. Compression eliminates bloat: editor metadata (Sketch, Figma, Illustrator data), comments, excessive decimal precision (10+ places instead of 2-3), unused definitions, empty groups, hidden elements, and redundant attributes.

Why SVG Compression is Lossless

The process is lossless—visual output remains identical because SVG is vector-based. We're removing code bloat, not visual data. Coordinates like 10.123456789 become 10.1—looks identical at normal zoom. Result: 20-70% file size reduction depending on source, with zero quality loss. Compressed SVGs load faster, use less bandwidth, improve Core Web Vitals.

How to Reduce SVG File Size in 3 Steps

Fast, free, and entirely in your browser

1

Add Your SVG Files

Drag and drop SVG files onto the page, or click "Add SVGs" to browse. Up to 50 files at once (10MB maximum per file). Accepts plain SVG, SVG with XML declarations, embedded images, fonts, filters, and SMIL/CSS animations.

2

Choose Optimization Preset

Six presets available. Recommended (default, SVGO preset-default with 40+ plugins, 30-50% reduction) for most SVGs. Maximum for smallest files (50-70%, may break complex SVGs). Safe for critical production files (metadata only, 10-25%). Icons for logos, Illustrations for artwork, Animated for SMIL/CSS animations.

3

Download Results

Processing is instant—50-200ms per typical SVG (5-50KB). Download files individually or grab everything as a ZIP. Filenames unchanged. Works on main thread (no Workers needed for text processing). Batch of 50 SVGs completes in under 10 seconds.

What Makes SVG Files Large?

Five common sources of SVG bloat

1. Editor Metadata (10-30% bloat)

Sketch, Figma, Illustrator embed app-specific data: <!-- Created with Sketch 57.1 -->, layer names, creation timestamps, tool versions, undo history, hidden layers. This appears in every export.

2. Excessive Precision (10-20% bloat)

Coordinates with 10+ decimal places: x="10.123456789012" when x="10.1" is visually identical. Design tools default to maximum precision unnecessarily.

3. Unused Definitions (5-15% bloat)

<defs> elements (gradients, patterns, symbols) never referenced in actual SVG. Editors export all definitions from libraries even if unused in this specific file.

4. Comments & Documentation (5-10% bloat)

Designer comments, version info, copyright notices, <title> and <desc> tags. Invisible to users but stored in file.

5. Redundant Attributes (5-15% bloat)

Default values explicitly stated: stroke-width="1" (already default), empty groups <g></g>, unnecessary id attributes never referenced.

đź’ˇ Combined Bloat: 35-90% of File Size

Export an icon from Figma: 2KB visual content, 5KB total file size. That's 60% bloat. SVGO-powered compression removes all five bloat sources while preserving visual output. This tool uses SVGO v4.0 with 40+ optimization plugins, XML parser/serializer, and multipass optimization for maximum efficiency.

⚡
Combined effect: All seven techniques together = 20-70% total reduction. SVGs exported from design tools (Sketch, Figma, Illustrator) see 50-70% reduction. Hand-coded SVGs see 20-40%. Already-optimized SVGs see 0-10%. Multipass optimization (running plugins twice) adds an additional 10-20% reduction.

Compress vs Optimize vs Minify: What's the Difference?

Three terms, same goal: smaller SVG files

Compress SVG

Focus: File size reduction through code cleanup and optimization.

Audience: General users (designers, content creators). This tool uses this term.

Optimize SVG

Focus: Code efficiency—removing unnecessary elements, simplifying paths, cleaning structure.

Audience: Technical users (developers aware of SVGO). SVGOMG uses this term.

Minify SVG

Focus: Developer-focused term from web development (HTML/CSS/JS minification). Removes whitespace, comments, shortens code.

Audience: Developers (web performance focus). Subset of full optimization.

🎯 Reality: All Three Are the Same

The terminology split is marketing/branding, not technical. All three achieve the same goal with the same techniques. Our tool does all three: compresses file size, optimizes code structure, minifies syntax. We use SVGO v4.0—the same engine that powers SVGOMG, command-line SVGO, and most build tools. The difference? We're browser-based (no installation), batch-friendly (50 files at once), and privacy-focused (no upload).

Your SVG Files Stay Private

100% browser-based processing using pure JavaScript

Unlike other tools that upload your SVGs to a server, we process everything locally. Your browser loads SVGO (pure JavaScript library from CDN), parses your SVG's XML structure, applies optimization plugins, and outputs the result—all in your device's memory. No upload. No storage. No exposure. Perfect for logo files (brand assets), client work, unreleased designs, proprietary icon libraries.

Works Offline After Page Loads

Once the page loads and caches SVGO from the CDN, you can disconnect from the internet and continue optimizing. Your SVG code stays completely private—never transmitted anywhere. Open DevTools Network tab to verify—zero file uploads. GDPR compliant by architecture. Technically impossible for us to see your files because they never leave your browser.

Frequently Asked Questions

Everything you need to know about SVG compression

Add your SVG file (drag-drop or click "Add SVGs"), choose Recommended preset for safe 30-50% reduction, then click Optimize. Processing is instant—50-200ms per file. Download individually or as ZIP. Works entirely in your browser using SVGO v4.0.

Remove editor metadata (Sketch/Figma data), simplify paths (reduce coordinates), optimize precision (3 decimal places instead of 10), minify code (remove whitespace), clean unused definitions. SVGO handles all of these automatically. Additionally, gzip compression on your server provides 60-80% further reduction for transfer.

There's no technical difference—both reduce file size using the same techniques. "Compression" emphasizes file size reduction. "Optimization" emphasizes code cleanup. Both use SVGO plugins to remove unnecessary code, simplify paths, and clean metadata. Same outcome, different marketing terms.

No. SVG compression is lossless because SVG is vector-based (mathematical descriptions, not pixels). We're removing unnecessary code (metadata, comments, excessive precision), not visual data. The SVG renders identically. At extreme zoom (50x+), aggressive precision reduction (1 decimal place) may show slight pixelation, but normal viewing is unchanged.

Five main causes: editor metadata (Sketch/Figma layers, timestamps), excessive coordinate precision (10 decimal places), unused definitions (gradients/patterns never used), comments and documentation, redundant attributes (default values explicitly stated). Combined, these can be 35-90% of the file. SVGO compression removes all bloat.

Removing whitespace, comments, and shortening code—similar to minifying HTML/CSS/JS. SVGO's minifyStyles plugin minifies CSS within SVG. This is a subset of full SVG optimization, which also includes path simplification, metadata removal, and structure cleanup. Developer-focused term.

Typically 20-70% depending on source bloat. Figma/Sketch exports: 50-70% reduction (heavy metadata). Illustrator exports: 40-60%. Hand-coded SVGs: 20-40%. Already-optimized SVGs: 0-10%. Maximum preset (floatPrecision=1, aggressive plugins) achieves highest compression but may break complex SVGs.

Yes. Recommended preset is optimized for web: removes editor metadata, inlines styles, optimizes paths, reduces precision to 3 decimal places. Use SVGZ (gzip) on your server for additional 60-80% transfer size reduction. Compressed SVGs improve page load speed and Core Web Vitals scores.

SVGO (SVG Optimizer) is a Node.js command-line tool for optimizing SVGs. It's the industry-standard optimizer used by Google, Figma, GitHub, and Webpack. This tool uses SVGO v4.0 in your browser—same engine, no installation required. Web-based alternative to command-line SVGO.

Depends on image type. Simple graphics/icons: SVG is smaller AND infinitely scalable. Complex images/photos: PNG is smaller (SVG requires many paths). SVG advantages: scalability, editability, CSS styling. PNG advantages: better for photos, universal compatibility.

Yes, batch process up to 50 SVG files at once. All optimized locally in your browser (sequential processing on main thread). Download individually or as a ZIP. Perfect for compressing entire icon libraries or asset folders. Processing is very fast—50 files in under 10 seconds.

No. SVG remains infinitely scalable after compression. We're removing code bloat, not vector data. Paths, shapes, and coordinates are preserved (just rounded to fewer decimal places). The mathematical descriptions that enable scaling are unchanged. Your SVG scales perfectly from 10px to 10,000px.
