  • **Minify mode** that strips whitespace, comments and redundant metadata
  • Prettier-style formatting and SVGO-style optimization under the hood
  • Configurable indent style (spaces or tabs) and indent size
  • Optional wrap column to keep long paths and attributes tidy
  • Consistent end-of-line style (LF / CRLF) for clean diffs across OSes
  • Drag-and-drop `.svg` files up to 5 MB or paste inline SVG markup
  • 100% client-side processing — your artwork never leaves the browser
  • One-click copy or download of formatted (`.formatted.svg`) or minified (`.min.svg`) output
  • Responsive UI that works nicely on laptops, desktops and tablets

🔧 How to Format or Minify SVG: Quick Guide for svg-formatter

1

1. Paste or Upload SVG

📥 Drag-and-drop your `.svg` file or paste raw SVG markup into the editor. The tool detects standard `image/svg+xml` content automatically.

2

2. Choose Format or Minify

✨ Select **Format** for human-readable markup (great for reviews and version control) or **Minify** for the smallest possible file size.

3

3. Tune Formatting Options

⚙️ Adjust **Indent Style** (spaces or tabs), **Indent Size** and optional **Wrap / Line Length**. These map directly to the underlying formatter settings.

4

4. Preview & Export

👀 Inspect the optimized SVG code, test it quickly in your project, then copy it to your clipboard or download the result as a new `.svg` file.

Technical Details

Beautification Engine (Format Mode)

Format mode uses a Prettier-style engine tuned for SVG XML markup. It focuses on readability and stable, predictable diffs.

AspectBehaviorNotes
Indent StyleSpaces or TabsConfigurable via **Indent Style** (maps to `indentStyle`).
Indent Size1–8 spacesControls nesting width when using spaces (maps to `indentSize`).
Wrap / Line Length0–120 columns`0` disables wrapping; otherwise long lines are wrapped around the chosen column (maps to `wrapLineLength`).
End-of-LineLF (`\n`) or CRLF (`\r\n`)Keeps line endings consistent across OSes (maps to `endOfLine`).
Output LanguageXML-style SVGMaintains SVG-compatible XML structure for safe embedding.

Minification Pipeline (Minify Mode)

Minify mode uses an SVGO-inspired pipeline focused on size reduction while preserving visual output.

StepDescriptionImpact
Remove commentsStrips `<!-- ... -->` comment nodes that do not affect rendering.Smaller files, cleaner diffs.
Drop redundant whitespaceCollapses unnecessary spaces, tabs and line breaks.Big wins for verbose editor-exported SVGs.
Trim metadataOptionally removes non-rendering metadata nodes when safe.Good for public production assets.
Normalize attributesSimplifies and reorders attributes in a stable way.More compact output, better cacheability.

Encoding & Compatibility

Output is UTF-8 SVG compatible with modern browsers and tooling, aligned with the SVG 2 specification.

CLI Alternatives for Power Users

Prefer terminal workflows or CI integration? Combine Prettier and SVGO for behavior similar to this tool:

Linux / 🍎 macOS

Beautify SVG with Prettier

npx prettier --parser xml --print-width 80 --tab-width 2 --write input.svg

Applies consistent indentation and line wrapping to your SVG markup.

Minify SVG with SVGO

npx svgo input.svg -o input.min.svg

Removes comments, metadata and redundant whitespace for smaller files.

Windows (PowerShell or CMD)

Pretty-print SVG using xmlstarlet (via WSL or native)

xmlstarlet fo --indent-spaces 2 input.svg > pretty.svg

Formats SVG/XML with a 2-space indent.

Minify SVG with SVGO (no global install)

npx svgo input.svg -o min.svg

Runs SVGO directly via `npx` for one-off optimizations.

Add Prettier + SVGO to your build or pre-commit hooks so designers can export raw SVGs and your pipeline keeps them optimized.

Practical Applications

Web Performance & Frontend Bundles

  • Reduce SVG payloads in design systems, icon sets and sprite sheets.
  • Inline minified SVG in HTML/CSS to save extra HTTP requests.
  • Improve Core Web Vitals by shrinking hero illustrations on landing pages.
<img src="/assets/hero.min.svg" alt="Optimized hero graphic" />
.icon-check { background-image: url('data:image/svg+xml;utf8,<svg ...>'); }

Design Handoff & Version Control

  • Beautify exported SVG before code review to make diffs readable.
  • Keep a pretty `.formatted.svg` for collaboration and a `.min.svg` for production.
  • Enforce consistent indentation and attribute ordering across a design system.

Mobile, Emails & Hybrid Apps

  • Minify inline SVGs in HTML emails for lighter campaigns.
  • Reduce app bundle size in React Native / Capacitor / Ionic when shipping many icons.
  • Save bandwidth for users on slow or metered connections.

❓ Frequently Asked Questions

❓What is SVG formatting?

Formatting (or beautifying) restructures your SVG markup with consistent indentation, line breaks and attribute ordering. It does not change how the image renders, only how the code looks and diff-behaves.

📏Will minification alter my SVG’s appearance?

In normal cases, no. Minification removes comments, redundant whitespace and non-rendering metadata. It is designed to preserve the visual result while reducing size. If you rely on special metadata for editing tools, keep a backup of the original file.

🔒Is my SVG uploaded to a server?

Never. All formatting and minification run entirely in your browser using JavaScript/WebAssembly. Your SVG files are not sent to any server or stored remotely.

🚀How much size can minification save?

Real-world savings are typically between **30% and 70%**, depending on how the SVG was exported and how much metadata or whitespace it contains.

⚠️Can removing `<metadata>` or comments break my workflow?

For public web graphics, removing metadata and comments is usually safe. However, if your design tools store editing data or licensing information in those sections, keep an original, unminified copy in version control for future edits.

Pro Tips

Best Practice

Keep an unminified `icon.formatted.svg` in your repo for clean diffs, then generate `icon.min.svg` as part of your build step.

Best Practice

Always include meaningful `<title>` and `<desc>` elements before minifying to keep your SVGs accessible to screen readers.

Best Practice

Combine SVG minification with HTTP compression (Gzip/Brotli) to squeeze even more bytes out of heavy illustrations and charts.

Best Practice

For icon sets, consider a sprite strategy: minify once, then reference icons via `<use>` instead of duplicating SVG code everywhere.
