The best LibreOffice alternatives
Updated Jul 2026
LibreOffice is a complete, free office suite that opens and exports a huge range of document formats, all on your own computer. If you need to edit documents, it is genuinely excellent. People look for an alternative when installing a whole office suite is more than they need, when they just want to convert a file, or when they also handle images, video, and audio. Here are the honest options. LibreOffice already keeps files local, so the difference below is weight and breadth, not privacy.

How to choose
If you need to write and edit documents, keep LibreOffice; nothing here replaces a full suite. If you mainly need to convert a document to another format, a word processor's export or an on-device converter is far lighter. And if you also convert images, video, or audio, an all-in-one on-device app covers documents and everything else in one place.
A note on privacy
Documents are often personal: letters, contracts, records. LibreOffice keeps them on your own machine, and an on-device converter does the same. The moment you switch to an online document converter, that file is uploaded to a server you do not control.
Morphjet converts 1,800+ formats on your own computer, with no upload and no account. Launching this July.
Questions
What is a lighter alternative to LibreOffice just for converting?
If you only need to change a document's format, a word processor's export feature or an on-device converter does the job without installing a full office suite.
Can I convert documents without uploading them?
Yes. LibreOffice and an on-device converter both work on your own computer, so the document is never uploaded. Online document converters are the exception.
Is there a LibreOffice alternative that handles more than documents?
Yes. An app like Morphjet converts documents alongside images, video, audio, RAW, and ebooks, which is broader than an office suite, though it does not edit documents.
