Question 1

What optimizations does this tool perform?

Accepted Answer

The optimizer removes XML declarations, HTML/XML comments, empty groups, data-name attributes (Adobe Illustrator cruft), and collapses excess whitespace. You can also optionally remove and <desc> tags. These changes reduce file size without affecting the visual output.

Question 2

Will optimization change how my SVG looks?

Accepted Answer

No. All removed elements (comments, empty groups, XML declarations) are non-visual. The optimizer includes a side-by-side preview so you can confirm the rendered result is identical before downloading.

Question 3

Why remove data-name attributes?

Accepted Answer

Adobe Illustrator exports SVGs with data-name attributes on every layer group (e.g., data-name="Layer 1"). These are metadata for Illustrator and have no effect in browsers — removing them reduces file size with no visual impact.

Question 4

Should I remove and <desc> tags?

Accepted Answer

For decorative SVGs used as background images or icons, removing them is fine and saves bytes. For SVGs used inline in HTML where screen readers should describe the image, keep them for accessibility. Toggle the option based on your use case.

Question 5

Is my SVG uploaded anywhere?

Accepted Answer

No. All optimization runs entirely in your browser. Your SVG markup never leaves your device.
