What is in the download

• A standalone Vite + React + TypeScript + Tailwind CSS project: src/tool holds the tool, shared pieces sit beside it
• package.json with exact versions plus a lockfile, so npm ci works
• README.md (run, build, embed in Next.js or plain React) and an MIT LICENSE

What the code does

• Tokeniser that protects text, style, script and CDATA
• Path data parser with arc flag handling and rounding
• Unused id removal that honours url(), href and CSS references
• Rasterising at any scale with a rendered before/after pixel check

Tech stack

React 19, TypeScript, Vite, Tailwind CSS 4, jszip.

Install and customise

The How to install and How to use tabs list the steps. In short: unzip, npm ci, npm run dev, then copy the tool folder into your own app if you want to embed it.

Good to know

• A browser-only tool: there is no backend or database in the code.
• It is deliberately conservative and does not merge paths or convert shapes; use svgo if you need those.
