Open an AppleWorks file — and turn it into a document you can actually use
There’s a particular kind of file that turns up when you clean out an old iMac or copy a relative’s backup CDs: the .cwk document. AppleWorks came free with millions of Macs between 1998 and 2007, so it’s what a whole generation of families used for letters, homework, club minutes, and memoirs — and modern macOS won’t open a single one of them. This tool will. Drag the file in and it’s converted right here in your browser into an .odt document that opens in Word, Pages, or LibreOffice, along with a plain-text copy and a preview you can read immediately. The whole thing runs locally, powered by the same document filters LibreOffice uses. Your file is never sent anywhere — a decade of someone’s personal writing has no business being uploaded to a server you’ve never heard of.
About AppleWorks
AppleWorks is really ClarisWorks wearing a new badge. Claris — Apple’s semi-independent software arm — had built ClarisWorks into one of the best-loved integrated suites of the 1990s. When Apple pulled Claris back in-house in 1998, it rebranded ClarisWorks 5 as AppleWorks 5, reviving a name Apple had first used for its Apple II productivity suite back in 1984. AppleWorks 6 followed in 2000, updated to run natively on Mac OS X, and Apple bundled it with iMacs, iBooks, and eMacs for years, which is why the format is so common in home archives from that era. But development essentially stopped in the early 2000s; the last meaningful update shipped in 2004, and Apple formally discontinued AppleWorks in 2007 as Pages and the rest of iWork took its place. iWork, notably, never opened AppleWorks spreadsheets or databases, and modern Pages can’t open AppleWorks files at all — so the .cwk documents of that decade were simply orphaned.
Frequently asked questions
Is it safe to use this with private family documents?
Yes — because they never leave your computer. After a one-time engine download of about 2 MB, all conversion happens inside your browser, even with the network unplugged. There is no upload step, no server-side processing, and your original files are never altered.
What’s the difference between AppleWorks and ClarisWorks files?
Very little — AppleWorks 5 and 6 are direct continuations of ClarisWorks, and both use the same .cwk lineage. You don’t need to work out which one made your file: the tool reads the file contents and handles both, along with earlier ClarisWorks versions.
The file I found has no extension at all. Can you still read it?
Yes. Files created on classic Mac OS often have no extension, because the Mac didn’t need one. Detection here is based on what’s inside the file, not its name, so an extensionless AppleWorks document works fine. BinHex (.hqx) wrappers from old downloads are handled too.
Will it look the same as it did in AppleWorks?
You’ll get an .odt file that opens in modern Word, LibreOffice, and Apple Pages, plus plain text and an on-page preview. Fonts, styles, and layout are recovered where the format allows; documents with elaborate frame layouts may simplify a little, but your words survive intact.
