Free PUB to PDF Converter
Convert Microsoft Publisher .pub files to PDF in your browser. The
file is not uploaded: Korva loads a local WebAssembly converter,
reads the document on your device and downloads the PDF from the same tab.
Free · No account · No server conversion · Works on Mac, Windows, Linux and Chromebooks
Ready when you are
Choose a .pub file to convert it to PDF in this browser. No upload, no account.
How it works
A local converter, not an upload form.
Most online Publisher converters send the document to a server. This page is different: the app code downloads once, then the conversion happens on your computer.
- 01
Choose a .pub file
Pick the old Microsoft Publisher file from your computer. The page does not upload it.
- 02
Convert in this browser
Korva loads a small WebAssembly engine and turns the recovered page content into a PDF locally.
- 03
Download your PDF
Save the PDF, print it, email it or open the desktop app if you want to adjust the page first.
When to use it
Convert pub to PDF without Publisher, uploads or an account.
This free PUB to PDF converter is for the exact job: open a .pub file,
export a PDF and keep sensitive newsletters, bulletins, member lists and client
drafts off upload-based converter sites.
If the PDF needs layout cleanup, the desktop Korva app uses the same local engine and also lets you edit and export for free. A one-time USD 49 Korva Pro licence adds editable saves, mail merge and master pages.
FAQ
Free .pub to PDF converter questions
Is this .pub to PDF converter really free?
Yes. The browser converter is free for opening a .pub file and downloading a PDF. There is no account, no subscription and no upload step.
Does my Publisher file get uploaded?
No. The converter loads Korva WebAssembly in your browser, reads the file on your device and creates the PDF locally. Cloudflare only serves the static page and app files.
What file types does it support?
The tool is built for Microsoft Publisher .pub files. It can also read Korva native packages, but the public workflow is optimized for .pub to PDF conversion.
What if the layout needs editing before I print?
Use the free Korva desktop app. The same engine opens the file offline, then lets you move text, adjust images and export another PDF. Korva Pro is only needed to save the editable .kva project and use repeat-work tools.
Will every old Publisher file convert perfectly?
No converter can promise perfect fidelity for every legacy .pub file. Korva recovers text and embedded images locally, then builds a practical PDF. Complex files may need a tidy-up in the desktop editor.
