As Microsoft kills off Publisher, LibreOffice steps in with free support for your PUB files

Microsoft's decision to retire Publisher has left many small businesses, schools, and hobbyists wondering what comes next for their existing files. Years of newsletters, flyers, brochures, and greeting cards are stored in the PUB format, and losing access to them is a real worry. Fortunately, LibreOffice is stepping in with free Support for PUB files, and there is no need to convert them first.

The open-source community has long positioned itself as a safety net for users stranded by changing software policies. This latest move fits that pattern well. Anyone holding a folder full of old Publisher documents now has a free, practical way to keep opening them.

Below, we look at what Microsoft announced, how LibreOffice handles PUB files, and what users should keep in mind as they plan their next steps.

Microsoft Confirms the End of Publisher

Microsoft has confirmed that Publisher will be discontinued, ending a run that began in the early 1990s. The desktop publishing tool was always a lighter alternative to professional layout software, aimed at people who wanted attractive documents without a steep learning curve.

Over the years, Publisher fell behind as Microsoft focused its energy on Word, PowerPoint, and cloud-based services. Many users noticed that updates became rare and that the app felt increasingly like a leftover from another era.

Once support ends, the app will no longer receive security patches or fixes. Files will still exist on your drive, but opening and editing them will become harder as time passes and Office versions are retired.

Why PUB Files Have Always Been Difficult

PUB is a proprietary format, and Microsoft never published full documentation for it in the way it did for some other Office formats. That made it hard for other applications to read these files accurately.

Users who tried to move away from Publisher often ran into broken layouts, missing fonts, and shifted images. Exporting to PDF preserved the look but removed the ability to edit the content.

With Publisher going away, this lock-in became a bigger problem. People needed a trustworthy way to reach their old work without paying for a subscription or keeping outdated software alive.

How LibreOffice Opens PUB Files Directly

LibreOffice relies on a dedicated import library to read Publisher documents. This lets you open a PUB file directly in LibreOffice Draw without any separate conversion tool or intermediate step.

Once the file is open, you can view the pages, inspect the text and graphics, and make edits. From there you can save the work in an open format such as ODG, or export it to PDF, images, or other formats you need.

This approach saves time and reduces the risk of damaging a file during a clumsy conversion. For anyone with dozens or Hundred of documents, that convenience matters a great deal.

What You Can Expect From the Results

Import quality is good, but it is worth being realistic. Because PUB is a closed format, some complex layouts may not appear exactly as they did in Publisher.

Simple documents such as flyers, posters, and basic newsletters tend to import well. Files with elaborate effects, unusual fonts, or heavy use of linked objects may need some manual cleanup after opening.

A good habit is to compare the imported file against a PDF export from Publisher if you still have access to it. That makes it easy to spot differences and correct them quickly.

Why This Matters for Schools and Small Businesses

Schools, nonprofits, and small companies often rely on Publisher for recurring materials such as event posters and annual reports. These organizations usually have limited budgets and little time to retrain staff on new software.

LibreOffice is free, runs on Windows, macOS, and Linux, and requires no licensing. That makes it an easy recommendation for groups that need to keep working without added expense.

It also lets them preserve their archives in an open format, which reduces the risk of facing the same problem again in the future.

Practical Steps to Protect Your Old Documents

The first step is to gather all your PUB files in one place and make a backup. Copy them to an external drive or a cloud folder before doing anything else.

Next, install the latest version of LibreOffice and test a few of your most important files. Open each one in Draw, check the layout, and save a copy in ODG and PDF formats.

If you find problems, note which kinds of documents are affected. You can then decide whether to fix them in LibreOffice or rebuild them from scratch in another layout tool.

Alternatives Worth Considering for Future Projects

Beyond simply opening old files, you may want a new tool for creating documents. LibreOffice Draw and Writer both handle many layout tasks, and Scribus is a free option designed specifically for desktop publishing.

Cloud tools such as Canva and Microsoft Word templates can also cover everyday needs like invitations and flyers. The right choice depends on how much control over layout you need.

Whatever you choose, favor formats that are open and well documented. That way your work stays accessible regardless of what happens to any single vendor.

A Reminder of the Value of Open Software

This situation highlights why open-source software matters. When a commercial product is retired, users of proprietary formats can be left with few options, while open projects keep adding compatibility.

LibreOffice's PUB support is the result of community effort and careful reverse engineering. It gives people a lasting way to reach their own data, which is exactly what a document format should allow.

If you have been putting off dealing with your Publisher files, now is a good time to act. With LibreOffice, opening them is free, direct, and refreshingly simple.
