Open a Publisher file without Publisher
Publisher .pub files — newsletters, brochures, flyers and cards — barely open anywhere outside Microsoft Publisher. Converting to PDF gives you a universally viewable, print-ready copy that keeps the layout, text and graphics, while your file stays private, processed entirely in memory inside a network-free sandbox and never stored.
About Converting Publisher to PDF
Microsoft Publisher (.pub) is a desktop-publishing format used for newsletters, brochures, flyers, cards and other page-layout designs. Like Visio, it is a closed Microsoft format that few applications can open, so a .pub is awkward to share with anyone who does not have Publisher installed — converting it to PDF solves that instantly.
PrivConvert renders your Publisher file through the LibreOffice engine and produces a PDF that keeps the page layout, text and graphics. Everything happens in server memory inside a network-free sandbox, and your file is discarded the moment the PDF is ready.
Common use cases
- Sharing a newsletter or brochure with people who do not own Publisher
- Sending a flyer or invitation to a print shop as a ready-to-print PDF
- Archiving Publisher designs in a portable, long-lived format
- Posting a Publisher-designed document online where PDF is expected
Tips for best results
- Publisher is a proprietary Microsoft format, so rendering uses an open-source interpreter (libmspub). Complex layouts, unusual fonts or effects can render slightly differently — review the PDF before printing or publishing.
- Embed or use common fonts where possible; missing fonts are substituted with close matches on the server.
- For a print shop, a PDF is usually exactly what they ask for and avoids any Publisher-version mismatch.
