SVG Optimizer / Minifier

Paste SVG markup to minify, clean, and optimize it locally with size savings and copy-ready output.

SVG input

Paste inline SVG markup, exported icons, badges, logos, and web graphics.

Processed locally in your browser Limit Browser memory. Your input is processed in your browser and is not uploaded or sent to a server. Avoid pasting production secrets, access tokens, private keys, passwords, or sensitive customer data unless you understand the risk.

SVG is treated as untrusted markup. This tool parses and rewrites source text only; it does not render SVG, execute scripts, or fetch external resources.

Optimized SVG

Valid SVG text output with savings, warnings, copy, and download.

Ready to optimize SVG

Paste SVG or load a sample, choose safe cleanup options, then optimize.

Output stays text-only. There is no unsafe SVG preview or DOM injection.

SVG Optimization Guide

Optimize SVG source without executing markup

Clean exported SVG, preserve responsive behavior, and compare byte savings before embedding icons, badges, logos, or illustrations.

What is SVG optimization?

SVG optimization removes optional XML overhead, comments, metadata, redundant spacing, and unused namespace declarations from vector source.

SVG minification

Minified SVG keeps the same markup intent while compacting whitespace and attribute spacing so inline SVG and asset files are smaller.

Preserve viewBox

The viewBox controls the internal coordinate system used for responsive scaling. Keeping it on by default protects flexible icons and logos.

Metadata and comments

Design exports often include editor metadata and build comments that are useful while editing but unnecessary in production SVG files.

Safe vs aggressive cleanup

Safe cleanup avoids rendering-sensitive rewrites such as path simplification, color conversion, style merging, or transform changes.

SVG Optimizer vs Image Compressor

Use this tool for text-based vector markup. Use Image Compressor for raster PNG, JPEG, and WebP files that need quality and format controls.

SVG Optimizer FAQ

Does this tool render my SVG?

No. SVG stays as source text in the editor and output panel. The tool does not inject unsanitized SVG into the Angular DOM.

Why preserve viewBox by default?

Removing viewBox can make SVG scale incorrectly in responsive layouts, icon systems, and CSS-sized containers.

Should I preserve IDs?

Enable Preserve IDs when labels, CSS, masks, clip paths, gradients, symbols, or fragment links depend on those identifiers.

Will scripts, event handlers, or external references run?

No. The optimizer does not execute scripts, event handlers, animations, embedded content, or external resources referenced by SVG markup.

Why avoid aggressive SVG optimization?

Aggressive rewrites can alter paths, transforms, fills, strokes, or accessibility relationships. This tool favors predictable cleanup.

Does this tool upload my SVG?

No. Validation, optimization, copying, and downloads run locally in your browser.
