Is my SVG file uploaded to a server?

No. All optimisation runs entirely in your browser using JavaScript string processing. Your SVG is never sent to any server.

Why are SVG files so large from design tools?

Tools like Inkscape, Adobe Illustrator, Sketch, and Figma embed editor-specific metadata (namespaces, layer names, guides, undo history references) that is invisible on screen but adds significant file size. The optimiser strips all of this out.

Will optimising break my SVG?

The visual output should be identical for all options except "Remove & " (which removes accessibility labels). The live preview updates in real time so you can verify the result before downloading.

Minify collapses all whitespace and newlines into a single line. This is safe for use in HTML, CSS, and JavaScript but makes the SVG unreadable in a text editor. Disable it if you need to keep the file human-readable.

Should I remove and ?

Only remove them for decorative SVGs (icons, backgrounds) where accessibility is not needed. For inline SVGs used as meaningful content, keep and so screen readers can announce them.

What SVG optimisation removes

Design tools like Figma, Illustrator, and Inkscape add significant bloat to SVGs — metadata, editor IDs, comments, and redundant attributes. Optimisation strips this without changing the visual appearance.

Frequently Asked Questions

Will optimisation change how my SVG looks?: With default settings, no. The tool removes metadata and whitespace, not visual elements. Aggressive options like removing IDs can affect CSS-targeted elements.
