To convert a PUB file to PDF: if you have Microsoft Publisher, open the file and go to File then Export then Create PDF/XPS. This is the most accurate method. If you do not have Publisher, the Univik PUB Converter opens PUB files and saves them as PDF on Windows without Publisher installed, preserving the original layout. For many files at once, it converts a whole folder in a single pass. The most common problem in any PUB to PDF conversion is font substitution shifting the layout. Embedding fonts before conversion prevents it.
Why Convert PUB files to PDF
Converting Publisher to PDF is the most reliable way to share a .pub file. A PUB file only opens cleanly in Microsoft Publisher, so sending one to a client, a printer or a colleague without Publisher leaves them unable to open it. PDF solves that. It opens on any device, locks your layout in place and is the format commercial printers ask for.
PDF is also the format Microsoft recommends for long term access to Publisher content. That recommendation carries more weight now because of what happens in October 2026.
The October 2026 Microsoft Publisher Deadline
Microsoft is retiring Publisher. In October 2026, Publisher reaches end of life. It will no longer be included in Microsoft 365 and existing installed copies will no longer be supported. Microsoft 365 subscribers lose access to the app entirely.
Support for the perpetual version ends on October 1, 2026, when Office LTSC 2021 reaches end of support. If you have a perpetual licence (Publisher 2021, 2019 or earlier), the app can still be installed and used after that date. You just lose updates and support. Anyone relying on a Microsoft 365 subscription needs to move their PUB files into a durable format before the deadline. PDF is the safest target for anything you need to view or print. For files you need to keep editing, see our guide on converting Publisher to Word and the full Publisher end of life guide.
Convert before you lose access, not after
Microsoft recommends converting your files before October 1, 2026. Once a Microsoft 365 subscription loses Publisher access, the most accurate conversion method (exporting from Publisher itself) is gone. If you have PUB files worth keeping, convert them while you still have a working copy of Publisher, even if you do not need the PDFs yet. For the full picture of what happens to PUB files after 2026, see our dedicated guide.
“The mistake we see most often is people converting PUB files at the last minute, in bulk, without checking the output. Then a printer rejects the file because the fonts were substituted and the spacing shifted. PDF conversion is easy. PDF conversion that a commercial printer will accept is where the detail matters. Embed your fonts, check the first page against the original and only then run the rest.”

Convert PUB to PDF with Microsoft Publisher
If you have Microsoft Publisher installed, exporting is the most accurate way to convert a PUB file to PDF. The Publisher to PDF export uses the application’s own engine, so it knows exactly how the file should look and the PDF matches the original.
Open the PUB file in Microsoft Publisher. Then click the File tab in the ribbon.
Click Export then Create PDF/XPS Document then Create PDF/XPS. A save dialog opens.
Choose your quality before saving. Click Options. For print, select High quality printing or Commercial Press and confirm fonts are embedded. For email or web, Minimum size keeps the file small. Click OK then Publish.
The Commercial Press setting embeds fonts and keeps images at full resolution. Use it for anything going to a professional printer. The Minimum size setting downsamples images and suits email but not print.
Convert a Publisher file to PDF without Publisher
You can convert a Publisher file to PDF without Publisher installed using the Univik PUB Converter. It runs offline on Windows, opens PUB files directly and saves them as PDF while preserving the original layout, fonts and images. No Publisher installation is required, which means it keeps working after the October 2026 retirement deadline.
Download and install the Univik PUB Converter on your Windows machine. It runs locally, so your files never leave your computer.
Add your PUB file or a folder of PUB files. The converter reads the Publisher format and displays the document ready for conversion.
Select PDF as the output format and convert. The converter saves each PUB file as a PDF with the layout intact. For the full feature set and download, see the PUB Converter page.
Why an offline converter matters for confidential files
Client contracts, internal financials and unpublished material should never be uploaded to an external server for conversion. A converter that runs locally on your own machine keeps the file on your computer from start to finish. This is also the only conversion route that continues to work for users who lose Publisher access after October 2026.
Batch Convert PUB files to PDF
Converting one PUB file to PDF is quick. Converting two hundred is a different problem. Opening each one by hand in Publisher and exporting it takes hours and invites mistakes. There are two reliable ways to convert PUB files in bulk.
Univik PUB Converter (no Publisher needed)
The Univik PUB Converter processes a whole folder of PUB files to PDF in a single pass. It does not depend on Publisher being installed, so it handles volume both before and after the 2026 deadline. Point it at a folder, select PDF and it converts every file while preserving each one’s layout.
PowerShell with an installed copy of Publisher
If you have Publisher installed and licensed, Microsoft’s own automation route, published as an example conversion script on its Publisher retirement page, is a PowerShell script that loops through a folder and exports each PUB file using Publisher’s engine. The core of the script calls the Publisher COM object:
$files = Get-ChildItem “C:\PubFiles” -Filter *.pub
foreach ($f in $files) {
$doc = $pub.Open($f.FullName)
$pdf = $f.FullName -replace ‘\.pub$’, ‘.pdf’
$doc.ExportAsFixedFormat([Microsoft.Office.Interop.Publisher.PbFixedFormatType]::pbFixedFormatTypePDF, $pdf)
$doc.Close()
}
$pub.Quit()
This requires a working Publisher install, so it stops being an option once a Microsoft 365 subscription loses Publisher access in October 2026. Run it while you still have the app, or use the Univik PUB Converter, which has no such dependency.
How to Fix Layout and Font Problems
Font substitution ruins more PUB to PDF conversions than any other issue. When the converting tool does not have the exact fonts your PUB file uses, it swaps in a substitute. The substitute has different letter widths, so text reflows, line breaks move and your layout shifts.
Embed fonts before converting. In Publisher, the Commercial Press PDF preset embeds fonts automatically. A dedicated converter that preserves layout embeds fonts as part of the conversion. This is the single most effective fix.
Check page one against the original before converting the rest. Convert one file, open the PDF beside the original and compare the first page. If the fonts and spacing match, the settings are right. Only then convert the rest.
For print, use 300 dpi and avoid aggressive compression. Low quality presets downsample images. Photos look fine on screen but blurry in print. Use a high quality or commercial preset for anything going to a printer.
If a layout breaks badly, the tool could not read the PUB format properly. Use Publisher directly or a converter built specifically for the Publisher format, which reads the file structure accurately rather than approximating it.
Which PUB to PDF Method Should You Use

| Many files, Publisher installed | PowerShell script |
| Confidential or client files | Any offline method. Keep files on your own machine. |
PUB to PDF: Frequently Asked Questions
Can I convert a PUB file to PDF without Microsoft Publisher?
Yes. The Univik PUB Converter opens PUB files and saves them as PDF on Windows without Publisher installed, preserving the original layout. It also converts folders of PUB files in one pass for batch jobs.
Why does my converted PDF look different from the original PUB file?
Almost always font substitution. The converting tool did not have the fonts your PUB file uses and swapped in replacements with different letter widths, which shifts the layout. Embed fonts before converting. In Publisher, use the Commercial Press PDF preset. A converter that preserves layout embeds fonts as part of the conversion.
How do I convert hundreds of PUB files to PDF at once?
Use the Univik PUB Converter, which processes a whole folder of PUB files to PDF in a single pass without Publisher installed. If you have Publisher installed, you can also run a PowerShell script that loops through a folder and exports each file using Publisher’s engine.
Will my PUB files still open after Publisher is retired in October 2026?
If you have a perpetual licence (Publisher 2021, 2019 or earlier), the app keeps working, just without updates or support. Microsoft 365 subscribers lose access to Publisher entirely. Convert important PUB files to PDF while you still have a working copy of Publisher, or use an offline converter that does not need Publisher installed.
Is it safe to convert confidential PUB files to PDF?
Only with an offline method. A converter that runs locally on your own machine keeps the file on your computer from start to finish, which matters for client contracts, financials and unpublished material. Uploading sensitive files to an external server for conversion exposes them to that server.
Does converting PUB to PDF keep the file editable?
No. PDF is a fixed layout format designed for viewing and printing, not editing. If you need to keep editing the content, converting to Word or another editable format is a different process. PDF is the right choice when you need the document to look identical everywhere and stay locked.
Converting PUB to PDF: Summary
For a single file with Publisher installed, export directly from Publisher using File then Export then Create PDF/XPS. It is the most accurate route. Without Publisher, the Univik PUB Converter opens and converts PUB files to PDF on Windows while keeping the layout intact. It converts whole folders in one pass for batch jobs.
Whatever method you pick, embed your fonts and check the first page against the original before converting the rest. That one habit prevents the layout shifts that cause most rejected print jobs.
