Microsoft Publisher files use a proprietary .pub format that nothing else opens natively. With Publisher retiring in , the window to convert your files is closing. This guide covers every method — PDF, Word, and image formats — with honest advice on what each option preserves and what it doesn’t.
You need Publisher to convert .pub files reliably. Office Professional Plus 2021 is the last version that includes it.

PDF is the right choice for archiving. It preserves everything — layout, fonts, images, colours, positioning — exactly as the original .pub file appears. The trade-off is that a PDF isn’t easily editable. If you just need a permanent, faithful copy of the document, this is the format.
- Open the .pub file in Microsoft Publisher.
- Click File → Export → Create PDF/XPS Document.
- Click Create PDF/XPS. Choose your save location and filename.
- Before clicking Publish, click Options to choose a quality level.
- Click Publish. The PDF is created.
The quality levels matter depending on what you’re doing with the file:
Standard — fine for email, screen viewing, and general archiving. This is the right choice for most people.
High Quality Printing — for documents you’ll print at home or at a copy shop (300 DPI for images).
Commercial Press — for professional print runs with strict colour requirements (3,600 DPI for line art).
Minimum size — smallest file size, lowest quality. Only use if file size is the priority.
For bulk archiving, Standard is all you need. The difference in visual quality between Standard and High Quality is only noticeable when printing.
Converting to Word — Editable, But Compromised
Publisher can save directly to .docx format. The bad news: this conversion is rough. Microsoft’s own documentation acknowledges that only text and basic font formatting survive the process.
- Open the .pub file in Publisher.
- Click File → Save As.
- Set the Save as type dropdown to Word Document.
- Click Save. Publisher warns you that design elements won’t be preserved.
- Open the saved .docx in Word. Reinsert graphics and adjust layout manually.
- Text content
- Font family, size, style
- Bold, italic, underline
- Font colour and effects
- All graphics and images
- Column layouts
- Text box positioning
- Page breaks
- Header/footer functionality
This works for text-heavy documents — newsletters, articles, reports where you mainly need the words. For anything with layout complexity (brochures, flyers, business cards, posters), the output is essentially unusable. Office Watch tested Microsoft’s recommended method and called it “better than nothing, but not much better.”
There’s an alternative route: export to PDF first (using the steps above), then open the PDF in Word. Word attempts to convert the PDF into editable content. Results are inconsistent — sometimes you get individual text blocks and images, sometimes the entire page imports as a single graphic. Worth trying, but don’t rely on it for important documents.
The honest answer: If you need to preserve both layout and editability, there isn’t a perfect conversion path. The most practical approach is to keep Publisher installed and edit .pub files directly. Office Professional Plus 2021 gives you that ability on a perpetual licence — it works indefinitely, even after the retirement date.
Converting to Image Formats
For flyers, posters, social media assets, and anything where you need a picture file rather than a document. Two approaches:
Direct from Publisher:
- Open the .pub file in Publisher.
- Click File → Save As.
- Select PNG, JPEG, or Enhanced Metafile from the file type dropdown.
- Click Change to set the resolution — High Quality Printing (300 DPI) for print, Standard for screen.
- Click Save. Each page in the publication saves as a separate image file.
Via PDF: Export to PDF first, then convert the PDF to images using any PDF viewer or converter. This gives you more control over which pages to export and at what settings.
Choose PNG for anything with text, logos, or sharp edges — it’s lossless and preserves crisp lines. JPEG works for photo-heavy layouts where file size matters. Enhanced Metafile (EMF) is useful for vector graphics you plan to insert into other Office documents like Word or PowerPoint.
What If You Don’t Have Publisher Installed?
The .pub format is proprietary to Microsoft Publisher. Without Publisher, your options are limited and the quality drops significantly.
LibreOffice Draw has partial .pub import support through the Document Liberation Project. It handles simple documents — a single-page flyer with basic text and a few images — reasonably well. Multi-page publications with text boxes, columns, precise positioning, and embedded graphics lose their layout substantially. Images may need reinserting. Always test with a sample file before committing to this route for a batch of documents.
Online converters (Zamzar, CloudConvert, and similar services) can attempt the conversion. Two concerns: privacy, because you’re uploading potentially sensitive business documents to a third-party server, and quality, which is typically worse than LibreOffice for complex layouts.
The honest recommendation: if you have .pub files that matter, install Publisher. Office Professional Plus 2021 is a one-time purchase at £69 and gives you full, native access to every .pub file. No workarounds, no quality loss, no privacy trade-offs. It’s the last Office version that includes Publisher, and the application works indefinitely on a perpetual licence — even after Microsoft ends official support.
Handling a Large Backlog
If you have hundreds of .pub files spread across shared drives and local machines, converting everything individually isn’t practical. Triage first.
Not every file needs converting. Many .pub files are one-off documents that were printed years ago and never needed again. Focus your effort on files that actually matter:
- Files you actively reference or update — anything still in use.
- Templates you reuse — letterheads, certificates, event programmes, branded documents.
- Legal or compliance documents that must remain accessible for a set retention period.
- Marketing materials with brand assets you may need to recreate or repurpose.
For everything on that list: create a PDF copy as the minimum archive. PDF preserves the document exactly and takes seconds per file. Then decide which files also need to remain editable — those are the ones worth the more labour-intensive Word conversion, or the ones where keeping Publisher installed is the better long-term answer.
For the rest — old one-off prints, outdated event materials, superseded drafts — a PDF archive is enough. If you never need to edit it again, you don’t need to fight with the Word conversion.
Timeline: Microsoft 365 subscribers lose access to Publisher on . Give yourself at least four to six weeks before the deadline to work through any conversion backlog — don’t leave it to the final week. If you have a perpetual licence (Office 2021), there’s less urgency since Publisher continues to run, but security updates stop on the same date.

Frequently Asked Questions
No. Word has no import filter for the .pub format. You need Microsoft Publisher to open .pub files. The workaround is to convert the file to PDF or Word format from within Publisher first, or to use LibreOffice Draw for a partial (and often imperfect) conversion.
Yes, if you have a perpetual licence. Office Professional Plus 2021 includes Publisher and runs indefinitely — the application doesn’t stop working on the retirement date. What ends is Microsoft 365 access to Publisher (subscribers lose it entirely) and security updates for Office 2021. The software itself continues to function.
Not directly. Your best route is to export from Publisher to PDF, then insert the PDF pages as images into PowerPoint slides. Alternatively, save individual pages as PNG or JPEG images from Publisher and insert those. Neither method gives you editable text in PowerPoint — if you need that, you’ll have to recreate the content manually.
For simple, single-page documents with basic formatting, LibreOffice Draw is usable. For multi-page publications with text boxes, columns, embedded graphics, and precise positioning, expect significant layout problems. Images often degrade or disappear, text reflows unpredictably, and complex designs lose their structure. Always test with a sample file before committing to batch conversion via LibreOffice.
