A browser-based tool to preview and export PowerWash Simulator game timelapses as JPEG ZIPs or animated GIFs.

• Auto-scan your save folder using the File System Access API (Chrome/Edge)
• Drag-and-drop or manual file picker as fallback for other browsers
• Live preview with configurable frame delay and end pause
• Frame subset selection — choose how many frames to include
• Export formats:
  • JPEG ZIP — lossless archive of selected frames
  • GIF — animated GIF (scaled to max 800x600)

npm install
npm run dev       # Start Vite dev server
npm run build     # TypeScript check + production build
npm run preview   # Preview the production build locally

Automatically deployed to GitHub Pages on push to main via .github/workflows/deploy.yml. The Vite base path is set to /pwste-web/.

The app parses PowerWash Simulator's binary timelapse save files (.sav), which contain LZ4 or Zstandard-compressed JPEG frames. It supports both in-progress saves (individual .sav files per frame) and completed saves (single concatenated file).

Save files are located at %appdata%\..\LocalLow\FuturLab on Windows.
