Online SVG Optimizer & Converter Online

Paste an SVG (or open a .svg file) to optimize it fast in your browser. Remove comments/metadata, clean up extra whitespace safely, and convert the result to an SVG string, a URL-encoded data URI, or a Base64 data URI.

Tip: URL-encoded data URIs are usually smaller than Base64 for SVG, but Base64 can be simpler in some contexts.

FAQ

Is this SVG optimizer really client-side (no upload)?

Yes. The SVG is processed in your browser and never sent to a server.

What does the optimizer remove?

It can remove XML comments and optional <metadata>, <title>, and <desc>, plus whitespace-only text nodes between elements.

Will minifying break my SVG?

This tool uses a conservative minify (mostly between tags). If your SVG relies on unusual whitespace behavior, disable minify and keep only comment/metadata removal.

What is the difference between URL-encoded and Base64 data URIs?

URL-encoded data URIs are often smaller for SVG and readable; Base64 is more opaque but can be easier to paste in some contexts.

Can I use the data URI in CSS?

Yes. Paste the generated string into CSS, e.g. background-image: url(...).

Why do I get an SVG parse error?

The input must be well-formed XML with a valid <svg> root. Fix mismatched tags/quotes and try again.

Does this tool optimize paths or simplify shapes like SVGO?

No. It focuses on safe cleanup (comments/metadata/whitespace) and conversion to data URIs without heavy geometry rewrites.
