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.

  1. 01

    Choose a .pub file

    Pick the old Microsoft Publisher file from your computer. The page does not upload it.

  2. 02

    Convert in this browser

    Korva loads a small WebAssembly engine and turns the recovered page content into a PDF locally.

  3. 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 lets you edit any file and export your first complete project free. A one-time USD 49 Korva Pro licence unlocks additional projects, batch archive conversion, 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 Korva desktop app. The same engine opens the file offline, lets you move text and adjust images, and includes export of your first complete project. Korva Pro unlocks additional projects, batch conversion and editable .kva saves.

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.
