When you need to inspect a file without opening the software that created it, compare these viewers by the formats and previews they support. The ranking weighs archive and code previews, in-file search, listed formats, maximum file size, and office-file preview, alongside primary access and pricing details such as free plans and paid-from prices. ViewAnyFile.app and OpenFiles appear first, followed by File Viewer. Check whether the listed formats and size limits cover your files, and whether search or previews for particular file types matter to your workflow.
31 file viewer software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
