Open your stuck files.
No software needed.

Your file is sent over an encrypted TLS connection to our secure conversion server. It is converted immediately and then permanently deleted — within 60 seconds, whether the conversion succeeds or fails. We never store, share, or analyse your file contents. The only data we log is: file size, conversion result (success or failure), and timestamp. No file names, no content, no metadata beyond size.

Microsoft retired Publisher from Microsoft 365 on October 1, 2026. Subscribers lost the ability to open or edit .pub files in Publisher after that date. Microsoft did not provide an alternative way to open .pub files — their suggested workarounds require a working Publisher installation, which M365 subscribers no longer have. OpenAny uses an open-source library (libmspub) to read .pub files directly, without requiring Publisher.

We show you an honest fidelity report after every conversion. If images are missing or formatting has shifted, we tell you exactly what happened and offer alternative outputs — such as extracted images and text — so you can still access your content. We never hide conversion problems behind a clean-looking but inaccurate PDF.

winmail.dat files are created by Microsoft Outlook when it sends email in Rich Text Format to recipients using non-Outlook email clients (Gmail, Apple Mail, Thunderbird). The real attachments are hidden inside the winmail.dat file. OpenAny extracts the actual files so you can open them normally.
