A little engine room.

Browser storage

Checking available storage…

Engine assets are fetched from pinned public sources and checked by size and SHA-256 before being cached. Cached engine assets are separate from your session files.

“Assets cached” means the listed engine files are present. To work offline, the application page and its code must also be cached using the application download below. Browsers may evict stored data.

Take the workbench offline

Download the static pages and application code, then download the engines needed by your tools below. This does not save your files.

Checking application cache…

OCR also needs MuPDF, and image OCR needs ImageMagick. STEP/IGES/BREP inputs need Open CASCADE; FBX/DAE inputs need Assimp. Browser storage can be evicted; recheck this page before disconnecting.

Loading engine manifest…

One download, local processing

Engines may be substantial, especially for video and specialist formats. Download on a stable connection and keep this tab open. Failed or incomplete downloads are never accepted into the verified cache.

Missing an engine?

If a public source is unavailable, the affected tool reports the failure. The app does not silently switch providers or upload files to another service.
