SVG Optimizer
Minify SVG files — strip Illustrator/Inkscape bloat, round decimals, drop comments. Typical 40–80% smaller files. Runs in your browser; brand assets stay local.

How SVG optimization works
ToolChop applies safe text-level optimizations to your SVG: stripping editor-specific metadata (sodipodi/inkscape attributes, XML comments, embedded titles and descriptions), removing default attribute values, collapsing whitespace, and rounding numeric values to a chosen decimal precision. Each optimization is independently toggleable so you can preview the effect before downloading.
Why a local SVG optimizer matters
SVGs in the wild are almost always brand logos, design system icons, or app artwork — proprietary creative work. Uploading them to a third-party optimizer is a needless data path. ToolChop runs the entire optimization in your browser.
What gets stripped
- Metadata blocks —
<metadata>,<title>,<desc>,<sodipodi:namedview>, Inkscape-specific elements - Editor attributes —
sodipodi:*,inkscape:*,illustrator:*, custom XML namespaces from design tools - Comments — XML
<!-- … -->blocks - Whitespace — newlines and multi-space between tags
- Default attributes —
stroke-width="1",fill-opacity="1",opacity="1"(no visual effect) - Optionally: IDs — only if your SVG doesn't use internal references
Frequently asked questions
How do I optimize an SVG file online for free?
Drop your .svg file or paste SVG markup. Toggle the optimizations you want — strip metadata, editor attributes, comments, whitespace, default attributes, IDs — and adjust decimal precision. The optimized SVG appears live with file-size savings. Copy or download. No account, no upload, no daily limit.
Does ToolChop upload my SVG?
No. The optimizer runs as pure JavaScript in your browser — regex and DOM-based string processing. Your SVG never leaves your device. This matters because SVGs that need optimizing are usually brand logos, design system icons, or app artwork — proprietary work.
Why is the privacy story important for an SVG optimizer?
SVG files in the wild are almost always brand logos, app icons, or design-system artwork — proprietary creative work. Uploading them to a third-party optimizer is a needless data path. ToolChop runs the optimization in your browser.
How much smaller will my SVG get?
Typical savings on Illustrator/Inkscape exports: 40–80%. Editor metadata (sodipodi: and inkscape: attributes, embedded XML metadata, comments, default attributes) can account for half the file size. Rounding decimals from 6 to 2 digits cuts another 20–30% on path-heavy SVGs.
Will optimization break my SVG?
Generally no — the default settings are safe. The side-by-side render compares the original and the optimized output so you can visually verify. The one place to be careful: stripping IDs breaks SVGs that use internal references (gradient definitions referenced by ID, animations targeting specific elements) — leave that off if your SVG uses <defs> with gradients or filter references.
What's editor bloat?
Adobe Illustrator and Inkscape add their own custom XML attributes and elements to SVGs they save — sodipodi:namedview, inkscape:label, illustrator:i, xmlns:dc, and similar. These store editor state (zoom level, layer visibility, ruler positions) that has no effect on rendering. Browsers ignore them entirely; stripping them is always safe.
What decimal precision should I pick?
2 (the default) is great for most use cases — sub-pixel accuracy on standard screens, dramatic file-size savings vs the 6-digit default many editors produce. Drop to 1 for icons/logos at small sizes where pixel-level precision isn't needed. Keep at 4+ for SVGs that will be enlarged dramatically (billboards, plotter cutting) where precision compounds.
Will stripping the namespace declarations break rendering?
Only the Illustrator/Inkscape-specific namespaces are stripped (xmlns:sodipodi, xmlns:inkscape, etc.) — not the core SVG and XLink namespaces. Standard browsers and SVG renderers will render the optimized output identically to the original.
Does it merge similar paths or simplify geometry?
No — ToolChop's optimizer is a 'safe' optimizer that only removes redundant text, not geometric simplification. For path merging, curve simplification, or other geometric optimization, use SVGO (Node CLI) with appropriate plugins; those operations can change rendering and need careful tuning.
Why is the optimized output sometimes only slightly smaller?
If your SVG was already optimized (saved from Figma, hand-written, processed by SVGO), there's not much further to strip. The optimizer is most effective on raw Illustrator/Inkscape exports, which are notorious for bloat.
Can I paste SVG markup directly?
Yes. Below the dropzone there's a paste textarea — paste SVG markup that starts with `<svg`, and the optimizer treats it the same as a dropped file. Useful for SVG from your code editor or a copied web inspector.
Why use ToolChop instead of an online SVG optimizer that uploads my file?
Two reasons. First, privacy — SVGs are usually brand artwork that should not casually travel to a third-party server. Second, no install — SVGO is the gold-standard CLI tool but requires Node.js; ToolChop runs in any browser with no setup. For everyday logo and icon cleanup, ToolChop is faster.
