How to Convert a .pub File to PDF (Free, Offline, No Publisher)

To convert pub to PDF for free without Microsoft Publisher, open the .pub file in Korva's offline converter and choose Export as PDF. The file is processed on your own computer, so nothing gets uploaded. If you still have Publisher installed, File > Export > PDF works too. Below are all the real methods, ranked, with the honest trade-offs for each.

A colleague emails you a newsletter from years ago. Or you dig an old flyer off a USB stick and just need a clean PDF to send or print. Then you double-click it and nothing happens, because the .pub extension wants a program you don’t have. Buying a whole Microsoft 365 subscription to open one file is ridiculous. So don’t. You have better options, and a couple of them are free.

The fastest way to convert pub to PDF (free, offline)

The route I reach for first is Korva, a desktop publishing app I helped build to read old Publisher files. There’s a free browser version that needs no install, plus a free desktop tier if you’d rather have the app on your machine.

What sets it apart from most converters is where the work happens. Your file never leaves your computer. The web converter runs the same Rust engine compiled to WebAssembly, so the conversion runs inside your browser tab. Nothing gets uploaded. No server touches it, and you don’t need an account.

Step by step

1. Go to the Korva converter and open the free web version, or download the desktop app for Windows, macOS, or Linux.
2. Click to open your file and pick the .pub document. Korva reads the text, accents and all, pulls out every embedded image, and reflows the lot onto an editable page.
3. Look over the page. Text and pictures come across faithfully, but the original layout sometimes needs a small nudge. Drag a box, fix a heading, done.
4. Set your page size (US Letter or A4) and orientation.
5. Click Export, pick PDF, and save it wherever you like.

That’s it. For a single document you’ll be done in under a minute.

A quick word on what ends up inside the PDF, since it trips people up. Embedded JPEG photos are stored losslessly (DCTDecode), so your images keep their quality. Text uses the standard PDF fonts with WinAnsi encoding, which keeps accented characters intact. Colour comes out as RGB, the right choice for screen viewing and most office, community, or short-run printing. Need true CMYK with bleed and crop marks for a commercial offset press? No free converter does that well, and Korva doesn’t pretend to. For anything short of a print shop, RGB is exactly what you want.

Method 2: Export from Microsoft Publisher (if you still have it)

Already have Publisher installed and licensed? Then it’s still the most accurate way to make a PDF from your own files, for the obvious reason that it wrote the format in the first place.

1. Open the .pub file in Microsoft Publisher.
2. Go to File > Export.
3. Choose Create PDF/XPS Document, then click the Create PDF/XPS button.
4. Pick a location, confirm the quality setting, and save.

The catch is getting your hands on it. Publisher ships only with certain Microsoft 365 plans on Windows, was never sold for Mac, and Microsoft has scheduled its retirement for October 1, 2026. After that date it drops out of Microsoft 365 and stops getting updates. If you landed here because Publisher already vanished from your subscription, our piece on Publisher’s end of life walks through what changes and how to keep your archive usable.

Fine if you have Publisher today, then. As a plan for next year, it’s a dead end.

Method 3: Online converters (read the privacy fine print)

Search “pub to pdf” and you’ll get a wall of sites promising instant conversion. Drop your file in, wait a few seconds, download the result. They do work, and for a throwaway document with nothing sensitive in it, they’re fine.

Here’s the part nobody puts on the homepage: how they actually do it. You upload your file to their server, their software converts it there, then you download the output. So a copy of your document, with whatever happens to be in it, lands on someone else’s hardware. Plenty of services say they delete files after an hour or a day. You’re taking their word for it, and trusting that the connection and storage held up in between.

A few more things to check before you hit upload:

• File size limits on free tiers, often just a few megabytes, which a photo-heavy .pub blows straight past.
• Daily conversion caps designed to nudge you onto a paid plan.
• Output quality, because some converters flatten the whole page to an image and lose selectable text.
• Ads and bundled downloads on the spammier sites.

If the document holds names, addresses, financial details, or anything you wouldn’t tape to a noticeboard, skip the upload tools. Use a converter that runs locally.

How the methods compare

People always ask about LibreOffice Draw, so here’s the honest read. It’s a solid free office suite, and Draw can sometimes open a .pub file through its import filter. The word “sometimes” is doing heavy lifting. Complex layouts, fonts, and images often arrive scrambled, shifted, or just gone. Give it a shot if it’s already installed, but don’t be shocked when the page looks wrong. Scribus, the other open-source layout tool people mention, doesn’t import .pub at all.

What about opening the file on a Mac?

Publisher never had a Mac version, so Mac users have always drawn the short straw with .pub files. Korva runs natively on macOS 12 and later, and the web converter works in Safari or Chrome with nothing to install. If that’s your situation, we wrote a dedicated guide on opening .pub files on a Mac.

And if you only need to see what’s inside the file before you decide how to convert it, our walkthrough on opening a .pub file without Publisher covers the view-only options too.

After the conversion: a few practical tips

Once the PDF exists, two small habits save you headaches later.

First, check the text reflowed where you expected. Old Publisher files leaned on overlapping text boxes and manual spacing tricks. If a heading lands somewhere odd, double-click it in Korva and drag it back before you export. Five seconds now beats reopening a finished PDF and starting over.

Second, keep the original .pub. Even with a PDF in hand, hang on to the source. A PDF is a snapshot. The .pub, or Korva’s editable .pwl format, is the thing you can still change later.

Prefer the keyboard? The free Korva tier includes a command-line tool, korva-cli, with an export subcommand for turning a .pub file into a PDF straight from the terminal.

Frequently asked questions

Can I convert a .pub file to PDF without buying anything?

Yes. Korva’s converter is free forever for opening .pub files and exporting PDFs, and it runs offline or in your browser. Online converters are also free for small files, but they upload your document to a server to do it.

Is it safe to convert pub to PDF online?

Depends on the file. Browser-based converters that process everything locally, like Korva’s web version, never upload a thing, so they’re safe even for sensitive documents. Upload-based tools send your file to their servers, so steer clear of them for anything private.

Will the PDF keep my images and accented text?

Yes. Korva stores embedded JPEG photos losslessly and preserves accented characters using WinAnsi encoding, so French, Spanish, German, and the like come through correctly.

Do I need Microsoft Publisher to make the PDF?

No. Publisher is only needed for the File > Export method. Korva, online converters, and LibreOffice Draw all work without it, which matters a lot given that Publisher retires on October 1, 2026.

Can Korva handle CMYK PDFs for professional printing?

No. Korva exports faithful RGB PDFs, which suit screen viewing and most office and short-run printing. Commercial offset work that needs CMYK, bleed, or crop marks calls for dedicated prepress software instead.

If a .pub file is all that stands between you and a clean PDF, you don’t need a subscription and you don’t need a sketchy upload. Try the free Korva converter, keep the file on your own computer, and have your PDF in about a minute.
