Comparison

OnlyOffice stands out for its very faithful Microsoft Office compatibility. LibreOffice is more feature-complete. CryptPad encrypts everything but is more limited.

This topic is chapter 7 of my book

It answers these questions, among others:

  • how do you convert your documents without breaking their layout?
  • editing, storage, collaboration: which tool for each need?
  • and what do you do with shared documents still in use?
