Frequently Asked Questions
Do I need Microsoft Publisher installed?
No. CalcHive converts your .pub file to PDF using LibreOffice on our servers. You never need Publisher installed on your device.
Is this free?
Yes, completely free. No account required, no watermarks, no file limits per day beyond our fair-use policy.
What happens to my file after conversion?
Your file is sent securely to CloudConvert, converted, and deleted immediately. It is never stored or shared.
Why can't I open a .pub file normally?
Microsoft Publisher is required to open .pub files natively. Since Publisher is being retired in October 2026, fewer people have access to it. Converting to PDF is the best long-term solution.
Will the layout be preserved?
For most Publisher documents — newsletters, flyers, certificates — yes. Complex custom fonts or linked images may occasionally differ slightly.
