How this shelf works
About documents tools
Documents tools handle the small, repeatable jobs that show up between real work: write, format, export. They are built as focused utilities, so each page does one job without asking you to create an account or install software.
Open a tool, add your input, adjust the settings, and download the result. Processing happens in the browser using the platform APIs available for that file type. Files are not uploaded to a server, so the tool keeps working offline once the page has loaded.
