Questions
Frequently asked
What happens to my file when I convert it?
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. We log only file size, conversion result and timestamp.
Why did Microsoft Publisher stop working in October 2026?
Microsoft retired Publisher from Microsoft 365 on October 1, 2026. Subscribers lost the ability to open or edit .pub files after that date. Microsoft's suggested workarounds require a working Publisher installation, which M365 subscribers no longer have. OpenAny converts .pub files using an open-source library without requiring Publisher.
Is there a file size limit?
Free users can convert files up to 50 MB each, with a limit of 3 files per session. A Batch Pass ($9 one-time) raises this to 500 MB per file with unlimited conversions for 24 hours. Pro subscribers get up to 1 GB per file.
Which formats are supported?
Input formats: .pub, .epub, .mobi, .azw3, .fb2, .pdf, .msg, .eml, .docx, .xlsx, .pptx. Output formats: PDF, ePub, MOBI, Text. Not all input formats support all output formats — the tool shows you which options are available for your file.
Can I convert files in bulk?
Yes. With a Batch Pass or Pro plan you can drop an entire folder of files and convert them all at once, then download the results. Free users can convert 3 files per session.
