Open a MacWrite II or MacWrite Pro file — no vintage Mac required
A lot of serious writing from the late eighties and early nineties lives in MacWrite II and MacWrite Pro files — theses, family histories, church newsletters, the manuscript your father kept meaning to finish. If you’ve pulled them off an old hard drive or a SyQuest cartridge and hit a wall, this is the other side of the wall. Drop a file here and your browser decodes it directly: you get a readable preview immediately, an .odt download that opens in modern Word, Pages, or LibreOffice, and a plain-text copy for good measure. The conversion uses libmwaw, the same Document Liberation Project library that powers LibreOffice’s classic-Mac support, compiled to run entirely on your own computer. Nothing is uploaded — writing this personal shouldn’t have to be trusted to some anonymous conversion server, so it isn’t.
About MacWrite II / Pro
When Apple handed MacWrite to its Claris subsidiary, Claris didn’t just patch the aging original — it rebuilt the program from scratch. MacWrite II, released in 1989, was a genuinely modern word processor for its day: style sheets, mail merge, strong import and export filters, and support for the multilingual text system Apple was developing. Its file format was completely different from the original MacWrite’s, which is why the two are treated as separate formats here. MacWrite Pro followed in 1993, adding tables, footnotes, text frames, and a cleaner interface, and it earned a loyal following among writers who found Microsoft Word 5 bloated and ClarisWorks too lightweight. But Claris had a problem: ClarisWorks was cheaper, did more, and was selling spectacularly. MacWrite Pro was quietly starved of development, received its last updates in the mid-1990s, and was discontinued by 1998 — leaving a decade of documents behind in a format nothing modern reads. This page reads it.
Frequently asked questions
Does converting mean sending my documents somewhere?
No — the opposite. A small engine (about 2 MB) loads into your browser once, and from then on every conversion happens locally, even offline. Your files stay on your machine from start to finish, and the originals aren’t touched.
How do I know whether my file is MacWrite II, MacWrite Pro, or something else?
You don’t have to know. These files almost never have extensions — classic Mac OS didn’t use them — so the tool identifies the format by reading the file contents. Whether it turns out to be MacWrite II, MacWrite Pro, or a different classic format entirely, it’s detected and handled automatically.
What happens to the formatting — the styles, tables, footnotes?
The output is an .odt file that opens in modern Word, LibreOffice, and Apple Pages, plus a .txt copy and an inline preview. Styles, footnotes, and most layout are recovered where the library can read them; unusually complex frame layouts may come out simplified, but the text always survives.
Is MacWrite II the same format as the original MacWrite?
No — and it’s a common surprise. MacWrite II was a ground-up rewrite by Claris with its own file format, incompatible with 1984-era MacWrite files. The good news is that this tool reads both families: original MacWrite has its own page here, and both convert the same way.
