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 its WebAssembly engine and turns the pages, laid out as in Publisher, 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 opens the file locally with its layout — text boxes, pictures and formatting where Publisher placed them — 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.
Before you convert
How this converter compares to upload sites
Search for “pub to pdf” and most results are upload converters: you send the file to a server, wait in
a queue, then download the PDF. That works for a flyer you would hang on a wall. It is a poor fit for a
church directory, a donor list or a client draft, because a copy of the document now sits on someone
else's computer. This page changes a .pub to PDF without that step.

What converts well — and what may need a tidy-up
Korva keeps the Publisher layout: pages at their original size, text boxes, pictures and shapes where
Publisher placed them, linked stories, and the formatting — fonts, colours, lists, tables and accented
characters included. Everyday bulletins, newsletters, flyers, cards and certificates usually come through
ready to print. Microsoft never published a full specification of the .pub format, so no
third-party converter is pixel-perfect on every file. In the browser, fonts that aren’t standard are
replaced, so check that text still fits; very old files, WordArt and unusual effects can arrive simplified.
If the PDF needs fixing, open the same file in the desktop app, which uses the
fonts installed on your computer and lets you adjust the frames and export again.
Not sure what is inside a file someone sent you? Look at it first with the free online PUB viewer, which runs the same engine and shows the pages before you save anything.
Converting a whole Publisher archive
This page converts one file at a time, which suits the occasional attachment. If you are rescuing years of bulletins or newsletters now that Publisher is no longer part of Microsoft 365, convert them in one pass with the desktop app's batch conversion (Korva Pro). The step-by-step plan is in how to batch convert .pub files to PDF, and what happens to your .pub files explains which copies to keep.
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. It opens the file offline with its layout and formatting, 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.
How do I change a .pub file to PDF without Publisher?
Open this page, choose the .pub file and wait a few seconds. Korva reads it in your browser and downloads the PDF. You do not need Publisher, Microsoft 365 or an account.
Does it work on a Mac or a Chromebook?
Yes. The converter runs in any modern browser on Windows, macOS, Linux and ChromeOS. Phones and tablets work for smaller files, but a laptop or desktop is more reliable for large ones.
Can I convert many .pub files at once?
The browser converter handles one file at a time. To convert a whole folder or archive, use batch conversion in the Korva desktop app, which is part of Korva Pro.
Will every old Publisher file convert perfectly?
No converter can promise perfect fidelity for every legacy .pub file. Korva lays out the pages the way Publisher did — text boxes, pictures and formatting in place — and builds the PDF locally. Fonts that aren’t standard are replaced in the browser, so check text fit; the desktop app can use the fonts installed on your computer and lets you edit before exporting.
