ONLYOFFICE Desktop Editors: when to install it, and when not to

ONLYOFFICE Desktop Editors is a free, open-source office suite whose documents, spreadsheets and presentations are closest in fidelity to Microsoft Office…

The short version

ONLYOFFICE Desktop Editors: Choose this over LibreOffice if you exchange files with Word users all day: its rendering of .docx formatting is noticeably closer to Microsoft's. Fewer features, better fidelity.

What it is for

ONLYOFFICE Desktop Editors is a free, open-source office suite whose documents, spreadsheets and presentations are closest in fidelity to Microsoft Office formats, including collaborative features if you pair it with a server. For anyone who must open complex .docx or .xlsx files without paying, it is the most compatible free option.

When to pick something else

The interface is less polished than LibreOffice, and without the collaboration server you only get the local editor. Very large spreadsheets can lag, and the ecosystem of templates and extensions is smaller than the older suites.

LibreOffice
Publisher's site ↗
Free · Open sourceWindows, macOS, LinuxA complete office suite with no account, no telemetry and no ribbon. Opens and saves .docx and .xlsx reliably enough for everyday work. Install it even if you own Microsoft Office, as a second opinion on stubborn files.
Sumatra PDF
Publisher's site ↗
Free · Open sourceWindowsOpens PDFs in under a second, remembers where you stopped reading, and has exactly no upsell. It also reads epub, mobi and cbz. There is nothing to configure, which is the whole appeal.
PDF24 Creator

Free · Closed sourceWindowsThe offline alternative to those 'free online PDF tools' that quietly upload your contracts to a stranger's server. Merge, split, compress, OCR, all on your own machine.
Calibre

Free · Open sourceWindows, macOS, LinuxAn entire e-book library manager: converts between formats, fixes metadata, and can send books straight to most e-readers over USB or email. Deeply unglamorous, extremely capable.

Where an independent review, audit or survey is mentioned, it is summarised in our own words with the source named and linked; our /sources page sets out that policy. The recommendation, the trade-offs and every 'skip it if' line are our editorial judgement.
