Why are SVGs exported from Illustrator or Figma so large?

Design tools embed editor metadata: Illustrator adds and namespaces, Adobe XMP metadata, author information, and grid settings. Figma embeds layer names and IDs. None of this is needed for rendering. The optimizer strips all of it, keeping only the visual content.

How much can SVG optimisation reduce file size?

Typically 30–70% reduction for Illustrator/Inkscape exports. Simple icons can shrink from 10 KB to 2–3 KB. Complex illustrations see smaller percentage reductions because the actual path data dominates.

Will optimisation change how the SVG looks?

Correctly optimised SVGs render identically to the original. The optimizer uses safe passes: removing metadata, compressing path data numerically, merging redundant elements. Aggressive passes (merging paths, removing IDs) are off by default and can occasionally affect SVGs that rely on CSS targeting.

Yes. Optimisation runs in your browser. Your file is never uploaded to a server.

SVG Optimizer

ImageOffline-ready

SVG Optimizer cleans up SVG files exported from Inkscape, Illustrator, Sketch, and Figma by removing editor metadata, comments, unused definitions, redundant attributes, and whitespace. Shows before and after byte sizes and the percentage reduction. Paste SVG code or upload an SVG file — smaller SVGs load faster and are easier to version-control. Runs entirely in your browser.

Your files and inputs stay in your browser — nothing is uploaded or stored.

What SVG Optimizer does

SVG Optimizer Paste or upload an SVG — strip Inkscape/Illustrator bloat, comments, and whitespace. Shows size savings. It lives in DevBench's Image collection — open it in any modern browser with JavaScript enabled. There is no install step and no account wall: you get the UI immediately so you can paste input, tweak options, and copy output during real debugging sessions.

Like the rest of DevBench, this workflow runs entirely in your browser by default. Your text and files are processed with client-side JavaScript, which means they are not sent to our servers for routine formatting or conversion — open DevTools → Network and you should see no upload when you use the core controls. That makes these tools practical for internal payloads, configs, and drafts when you want to avoid unnecessary cloud round-trips.

Start from the controls above: paste or type into the labelled fields, upload when the tool supports files, and watch results update as you work. If output looks unexpected, verify encoding (UTF-8), line endings, and whether the tool expects structured input such as JSON, YAML, CSV, or hex. Many utilities include copy buttons or downloadable results so you can drop answers straight back into tickets, CI logs, or documentation.

When to use it

Quick one-off checks during development — faster than spinning up a REPL when you only need a transform or sanity check.

Sharing your screen: everything stays local to the browser tab so you can demo without pushing sensitive data through a backend.

Pairing with related DevBench tools via the "More Imagetools" links when your task spans encoding, parsing, or formatting.

Teaching or documentation walkthroughs where readers can reproduce steps without installing CLI tooling first.

If you need deterministic automation at scale, shell scripts and CI pipelines still win — use DevBench to prototype the transform and validate edge cases, then port the same logic into your stack when you are happy with the behaviour.
