What does an SVG optimizer actually remove?

Primarily: XML declarations, DOCTYPE declarations, editor metadata (Inkscape/Adobe/Sodipodi namespaces and elements), HTML comments, blocks, and unnecessary whitespace. These elements serve no purpose in browser-rendered SVG.

Will optimizing break my SVG?

The optimizer only removes elements that are safe to strip: editor metadata, comments, and whitespace. It never removes drawing elements, paths, shapes, or style rules. The Preview panel lets you verify the result before downloading.

Should I remove and ?

By default, and are preserved because they improve SVG accessibility — screen readers use them to describe the graphic. Remove them only if the SVG is purely decorative and accessibility isn't a concern.

What is decimal precision?

SVG coordinates (like in path d attributes) often contain many decimal places: e.g., 123.45678901. Reducing precision to 2 gives 123.46. This shrinks file size with imperceptible visual change for most graphics. Icon SVGs are particularly well-suited to precision 1–2.

Is this as good as SVGO?

Zolkit's SVG Optimizer covers the most impactful optimizations: metadata removal, namespace stripping, whitespace minification, and precision reduction. For the most advanced transforms (shape merging, path simplification), SVGO CLI may achieve additional savings.

Can I optimize multiple SVG files?

Currently the tool processes one file at a time. Batch SVG optimization is on the roadmap.

SVG Optimizer

Minify SVG code, strip editor metadata, and reduce file size — all in your browser.

Input

Optimized Output

Paste SVG code or drop a .svg file to get started.

Optimize SVG Files Instantly in Your Browser

SVG files exported from design tools like Figma, Illustrator, or Inkscape are bloated with editor-specific metadata, comments, and formatting. Zolkit's SVG Optimizer strips all of that away, delivering lean, production-ready SVG code.

Strips Editor Cruft

Removes Inkscape, Sodipodi, and Adobe metadata, namespaces, and comments that bloat SVG files exported from design tools.

Instant Optimization

Pure JavaScript — no server round-trip, no WASM compile time. Results appear as you type.

Configurable

Toggle which elements to remove: comments, metadata, title, desc. Set coordinate decimal precision.

100% Private

Your SVG code never leaves your browser. Optimized in-memory, no server, no logging.

Free Forever

No account, no limits, no paywalls. Paste your SVG and download.

Live Preview

See how your SVG looks after optimization. Verify that nothing important was removed.

How to Optimize SVG Files

1
Paste your SVG code into the input box, or drop a .svg file onto the page.
2
Review the options panel and toggle which elements to remove.
3
Copy the optimized code or click Download to save the file.
