Free Online SVG Formatter
SVG Formatter is a browser-based toolkit for cleaning up, compressing, validating, previewing, and encoding SVG files. Five specialized tools cover every step of the SVG code workflow: a beautifier that restructures messy markup with proper indentation; a minifier that strips metadata and collapses whitespace to shrink file size; a validator that checks syntax and flags errors with line numbers; a live viewer with zoom controls; and a Base64 converter for embedding SVG directly in HTML or CSS. Upload existing SVG files by dragging them onto the workspace or clicking the upload button, then format, optimize, and export the results. Everything runs client-side, so your files stay private and never reach an external server.
SVG Formatter
Beautifies SVG code with configurable indentation using 2-space, 4-space, or tab formatting for clean, readable markup.
SVG Minifier
Strips comments, XML declarations, empty attributes, and whitespace to produce the smallest possible SVG file.
SVG Validator
Checks SVG syntax for XML parsing errors, missing tags, and non-SVG elements with line-by-line error reporting.
SVG Viewer
Renders SVG with a live preview and zoom controls from 25% to 400% on a transparency-indicating checkerboard.
SVG to Base64
Encodes SVG as Base64 strings, data URIs, and CSS background snippets. Includes a decode tab for reverse conversion.
Online SVG Formatter with Beautifier and Minifier
SVG files exported from design tools like Figma, Illustrator, and Inkscape often contain dense, single-line code packed with redundant metadata. This formatter restructures that output into clean, human-readable markup with proper nesting and consistent indentation. Choose between 2-space, 4-space, or tab indentation depending on your project conventions. The side-by-side view shows your original input on the left and the formatted result on the right, making it easy to compare before downloading or copying.
Configurable Indentation Options
The indent controls sit directly in the output toolbar. Click 2 spaces, 4 spaces, or Tab to reformat instantly. Switching between options updates the output in real time without needing to re-upload or re-paste your code.
Minify SVG for Production
The Minifier tab does the opposite of formatting. It removes XML declarations, DOCTYPE tags, HTML comments, empty class and style attributes, data- attributes, and redundant opacity values. Whitespace collapses and all line breaks disappear, leaving the smallest possible SVG that renders identically. This is ideal for production web assets where every byte counts for page load performance.
Validate, Preview, and Convert SVG Files
Beyond formatting and minification, the toolkit includes three additional tools that handle common SVG tasks. The validator checks your code for structural issues using the browser's built-in XML parser. Each error and warning appears with a line number for quick debugging. The viewer renders your SVG on a checkerboard background with zoom controls from 25% to 400%, letting you inspect fine details or verify transparency. The Base64 converter encodes your SVG into a ready-to-use data URI for embedding in HTML img tags, CSS background-image properties, or JSON payloads.
Catch Syntax Errors Before Deployment
Broken SVG files can cause missing graphics, layout shifts, and render failures. The validator catches unclosed tags, missing root elements, absent xmlns declarations, and non-SVG HTML elements before those issues reach production. A green badge confirms valid markup when no problems are found.
Encode SVG as Base64 for Inline Embedding
Base64-encoded SVGs eliminate extra HTTP requests by embedding the graphic directly in your code. The converter provides three ready-to-copy outputs: a raw Base64 string, a complete data URI, and a CSS background-image snippet. The decode tab reverses the process, turning any Base64 SVG string back into editable SVG code.
Free SVG Formatter for Developers and Designers
Whether you need to clean up exported SVG assets, compress files for a web project, or validate markup before deployment, this tool handles it in seconds. Open the page and every feature is ready to use, with full access from the first visit and nothing required to get started. Your files remain completely private throughout, and closing the tab clears everything from memory.
No Signup and No File Size Limits
Jump straight into formatting, minifying, or validating without setting up an account or choosing a plan. The full toolkit is open to everyone, with unlimited use and nothing locked behind a paywall. Run as many SVG files through it as your project demands.
Client-Side Processing for Privacy
Every operation runs entirely within your browser without any server communication. Your SVG code is never uploaded, transmitted, or stored outside your device, making this a reliable choice for proprietary design assets, brand files, or any graphic content that needs to stay off external servers.
