Open a MacWrite file — forty years later, in your browser
If you’ve just rescued files from a Mac Plus, an SE, or a stack of 400K and 800K floppies, there’s a good chance the letters and stories on them were written in MacWrite. These are some of the oldest personal computer documents in existence — genealogists find family histories in this format, and estates turn up manuscripts nobody has been able to read in decades. This page opens them. Drop a file in and it’s decoded on the spot, in your browser, into a preview you can read now and an .odt file that opens in Word, Pages, or LibreOffice, with a plain-text copy alongside. The engine is a browser build of libmwaw, the Document Liberation Project library behind LibreOffice’s own legacy-Mac filters, and it runs entirely on your machine. A forty-year-old family letter deserves better than a trip through somebody else’s server, so it never takes one.
About MacWrite
MacWrite shipped in January 1984 with the very first Macintosh — it was one of the two applications (alongside MacPaint) that Apple used to show the world what a graphical computer was for. Written by a small team led by Randy Wigginton, Apple employee number six, it gave ordinary people something almost nobody had seen before: true WYSIWYG writing, with multiple fonts, sizes, and styles visible on screen exactly as they would print. For many families, a MacWrite document is literally the first thing anyone ever wrote on a computer. Because Apple bundled it free with every Mac, it dominated early Mac writing — so thoroughly that competitors complained it was crowding them out. Apple transferred MacWrite to its Claris subsidiary in 1987, where it was eventually succeeded by the rewritten MacWrite II in 1989. Files from the original line kept circulating well into the 1990s, and they’re still turning up on floppies today — readable again, it turns out, with the right software.
Frequently asked questions
These are personal letters. Where do they go when I convert them?
Nowhere. The converter runs completely inside your browser — a one-time download of roughly 2 MB, after which it works even offline. Your files are read locally, never uploaded, and never modified; you just get new copies in modern formats.
My files from the old Mac don’t have extensions. Is that a problem?
Not at all — it’s expected. Classic Mac OS identified files internally, so genuine MacWrite documents usually have no .mw or .mcw at the end. The tool identifies the format by reading the file itself, and it can also unwrap BinHex (.hqx) files from old transfers.
How faithful is the converted document?
You get an .odt (opens in modern Word, LibreOffice, and Apple Pages), a .txt copy, and an inline preview. MacWrite documents are relatively simple, so fonts, styles, and layout generally come through well. The original 1984 bitmap fonts don’t exist on modern systems, so substitutes are used.
How old a MacWrite file can this actually read?
All the classic versions — including documents from the very first releases in 1984. libmwaw was built specifically to recover early Macintosh formats, and MacWrite was among the first it supported. If your file came off a 400K floppy from the original Mac, it should still open here.
