Does this tool upload my SVG anywhere?
No. Parsing, live preview rendering, and SVGO optimization all run locally in your browser (optimization runs in a Web Worker) — nothing is uploaded to a server.
SVG Editor & Optimizer
Upload, paste, or drag-and-drop an SVG to preview it live and optimize it with SVGO entirely in your browser — see before/after size savings, tweak SVGO plugin options, and export the result as a file, data URI, or JSX component.
Useful for: svg, svgo, optimizer, developer tools, image, compression, editor.
Common questions
What optimizations does the SVG optimizer apply?
It runs Google's SVGO library with togglable options: remove metadata, remove comments, remove editor namespace cruft (Inkscape/Sketch/Figma), minify whitespace, adjustable numeric precision, remove IDs, remove useless stroke/fill, and multipass optimization.
Is it safe to preview an untrusted or unknown SVG file?
Yes — the live preview renders the SVG inside an img tag pointed at a local blob URL, which browsers sandbox from executing embedded script tags or event handlers, unlike inlining the SVG directly into the DOM.
What happens if my SVG markup is invalid?
The editor validates markup as you type using DOMParser and shows an inline error banner with the parse failure message instead of crashing the preview or optimizer.
Can I export the optimized SVG as a React component?
Yes — alongside downloading the optimized .svg file, copying the raw markup, or copying a data URI, you can copy a ready-to-use JSX/React functional component snippet.
Will it work on large SVG files like exported maps or icon sets?
Yes. Parsing and optimization are debounced and offloaded to a Web Worker so typing stays responsive, with a processing indicator for larger files.
