"Why won't my computer open this file?" usually has a dull answer: showing a document requires a decoder for that particular format, and your machine only ships the handful everyone has. Everything else arrived in the world attached to an application you do not own.

Doconut.app renders the file on a server and sends your browser the pages, so the missing application stops mattering. It is free, and it covers 73 file extensions — a specific number rather than "anything", which is worth saying plainly: if your extension is on the list it opens, and if it is not, no online viewer helps.
