File Operations

The File category covers compression, format conversion, and PDF editing entirely in the browser. You can create and extract ZIP archives (including password-protected ones) and TAR.GZ files, combine several images into one PDF, reorder and compress PDF pages, and repair a CSV that comes out garbled in Excel. Files are never sent to an external server and are processed entirely in your browser, so these work even where software installation is restricted.
