SVG optimizer for reducing markup and file size. Choose cleanup options, compare the original and optimized previews, and check the result before replacing your file.
The SVG Optimizer cleans SVG markup using the options you select. Upload a file or paste its source, run optimization, and compare the output with the original. File-size savings and visual changes depend on the source and settings.
Remove viewBox can remove viewBox. Keep it when the asset relies on it for scaling. Remove title elements and Remove desc elements delete <title> and <desc>; review accessibility requirements before selecting them.
Remove comments removes blocks such as <!-- ... -->. Metadata removal can reduce editor-specific information, but keep anything your workflow requires.
Other controls include removing redundant stroke or fill, cleaning unused IDs, minifying styles, converting styles to attributes, removing unused namespaces, and cleaning numeric values. These changes can affect an asset's use outside the preview, so check external styles and references too.
Collapse empty groups can simplify <g> wrappers. Review grouping, transforms, and styles in the output rather than assuming every wrapper is unnecessary.
Inspect colors, gradients, clipping, thin strokes, and text. Test the asset at the sizes you will use, and confirm that references to IDs still work when it is embedded in a page or sprite.
A matching preview does not establish that accessibility information, external CSS, or application references are intact. A smaller file is useful only if it still meets those requirements.
Use reviewed output for icons, logos, illustrations, or component libraries. Do not assume a fixed compression percentage or no quality change for every file.
Follow your organization's handling requirements before entering unreleased branding or confidential design work. Optimization is not a guarantee that an SVG is safe to embed.
