SVG Optimizer
Optimize SVG files with SVGO — the industry-standard SVG optimization library. Strip metadata, collapse groups, minify paths, remove unused definitions, and shrink file size by 40-80% without any visible quality loss.

SVG files exported from design tools like Figma, Illustrator, and Sketch typically carry a lot of dead weight — comments, editor metadata, unused namespaces, redundant transforms, precise-to-15-decimal-places numeric values, and dozens of nested groups that produce identical rendered output. This SVG Optimizer runs your SVG through SVGO — the industry-standard optimization library used by every major design tool export pipeline and icon library — and produces a version that renders identically but weighs 40 to 80 percent less. The savings compound: an icon library with 200 icons can drop from 200 KB to 40 KB with no visible difference.
Every optimization option is exposed as a toggle so you can be conservative when needed. Dangerous transforms like removeViewBox (which breaks responsive scaling) and removeDimensions (which needs viewBox to work) are off by default. Cleanup IDs is safe unless your SVG uses those IDs in masks, filters, or gradients — the tool warns when a transform might have side effects. Multipass mode runs the optimizer multiple times until no further improvements can be made, catching optimizations that only become possible after earlier passes. The library used is the official svgo/browser build — results are identical to running svgo on the command line or via the Figma export dialog's 'optimize' checkbox.
How to Use
Paste your SVG code into the input box, or click 'Upload SVG' to load a file.
Toggle optimization options in the sidebar — defaults are safe (never removes viewBox or dimensions).
The optimized SVG appears on the right with a size-reduction stat.
Copy the output, download as a .svg file, or preview the rendered result at the bottom.
Frequently Asked Questions
What is SVGO?
SVGO (SVG Optimizer) is the industry-standard SVG optimization library used by design tools (Figma exports), icon libraries (Lucide, Heroicons), and CI pipelines everywhere. It applies dozens of small transforms — removing unnecessary attributes, collapsing groups, merging paths — that together shrink SVG files by 40-80% without any visible quality loss.
Which options are safe to enable?
The defaults are safe for every use case. removeComments, removeMetadata, cleanupIds, and convertColors have zero visual impact. removeViewBox is DANGEROUS — removes responsiveness — and stays off by default. removeDimensions is safe only if your SVG has a viewBox and you plan to size it via CSS.
Why did my SVG break after optimization?
Usually one of three things: (1) you enabled removeViewBox, breaking scaling. (2) you enabled cleanupIds and the SVG referenced those IDs elsewhere (masks, filters, gradients). (3) you enabled minifyStyles and the CSS was more complex than the minifier expected. Toggle those off and re-optimize.
Is this the same SVGO used by other tools?
Yes — this tool uses the official svgo npm package (browser build) with the preset-default plugin group, same as SVGO's own online demo and CI plugins. Results are identical to running svgo on the command line.
Is my SVG uploaded anywhere?
No. SVGO runs entirely in your browser via the svgo/browser entry point. Verify by opening the network tab and optimizing an SVG — zero outbound requests. Safe to paste proprietary logos and brand assets.
