Document viewer, archive and font tools
Document viewers and converters usually require handing the whole file to a remote service. These tools instead parse supported Office packages, spreadsheets, ebooks, fonts, and archives inside your browser. You can preview a document without installing an office suite, or rebuild a checked output when conversion is the goal. Complex proprietary layouts have honest limits, but your source file never becomes someone else's server data.
