SVG Optimizer

Reduce SVG markup and file size using SVGO. Paste code or choose a file, review the optimized source, then copy or download it without uploading the graphic.

SVG input

Optimization does not make untrusted SVG files safe. Review scripts, links, and external resources before publishing the result.

Optimization options

How SVG optimization works

The optimizer parses the SVG structure and applies SVGO’s established default transformations. Multiple passes can find additional reductions, readable output keeps formatted markup, and removing width and height can help a viewBox-based SVG respond to its container.

Keep the original file until you have checked gradients, filters, masks, fonts, IDs, and animation in the environment where the SVG will be used.

Frequently asked questions

What does SVG optimization remove?

SVGO can remove redundant metadata, unused definitions, unnecessary precision, and verbose markup while combining safe transformations that preserve the rendered graphic.

Will optimization change how my SVG looks?

The default settings are designed to preserve appearance, but complex SVGs can rely on unusual authoring details. Compare important files in their final environment before replacing the original.

Why does the optimizer preserve the viewBox?

The viewBox defines an SVG’s internal coordinate system and helps it scale responsively. This tool keeps it by default, even when other redundant attributes are removed.

Does SVG optimization make an untrusted file safe?

No. Optimization is not a security scan or complete sanitizer. Review scripts, links, embedded content, and external resources before publishing an SVG from an untrusted source.

Are my SVG files uploaded?

No. The SVG is read, optimized, copied, and downloaded locally in your browser.
