Fernwork runs entirely in your browser, which means it needs JavaScript enabled to work. Please enable JavaScript and reload the page.

What this page does: Open, inspect and edit common file types directly in your browser — no software install, no upload. Fernwork viewers support documents (DOCX, ODT, RTF, EPUB, HTML, Markdown, text), spreadsheets (XLSX, XLS, ODS, CSV, TSV, JSON, NDJSON), CAD drawings (DXF), point clouds (E57/LAS/LAZ/PLY/PCD/XYZ), GIS shapefiles, BIM models (IFC), 3D meshes (STL/OBJ/PLY/3MF), PowerPoint presentations, SVG graphics and SQLite databases. Files stay on your device thanks to client-side parsing.
