A browser-based viewer for obsolete documents, archives, media, and disk-image formats.

Landing page captured for the 2026-10-07 issue.

For: People trying to inspect legacy files on current devices
Worth noticing: The page says format detection reads a file’s first bytes, so a missing or misleading extension need not determine which viewer it uses.

Field notes

Formats are organized into several groups, including old office documents, compressed archives, media, and disk images. The FAQ says the viewer identifies files by inspecting their first bytes and that JavaScript and WebAssembly handle viewing in the browser. It also says a viewer is retained on the device for offline use; ZX Spectrum tapes, Shockwave movies, and C64 SID tunes are listed as future additions.
