Microsoft Publisher is being retired in October 2026, bringing an end to a desktop publishing tool that many businesses have used for years to create flyers, brochures, labels, newsletters, forms, posters & internal templates.
For some businesses, Publisher may barely be used anymore. For others, it may still be quietly sitting behind important documents that are opened once a month, once a quarter, or only when someone urgently needs to update an old template.
That is where the risk comes in
Publisher is not disappearing in a “your files vanish overnight” way, but if your business still relies on .pub files, now is the time to check what you have, what still matters, & what needs to move into another format or platform.
Microsoft has confirmed that Publisher will reach end of life in October 2026.
After that point, Publisher will no longer be included in Microsoft 365, & Microsoft 365 subscribers will no longer be able to open or edit Publisher files using Publisher.
That means businesses using Publisher through Microsoft 365 should not leave old .pub files untouched until the deadline. If those files are still needed, they should be reviewed & converted before Publisher becomes harder to access.
Your .pub files will not simply delete themselves.
The issue is access.
If you currently use Publisher through Microsoft 365, you may lose the ability to open & edit those files in Publisher after retirement. If you have an older perpetual version of Publisher, the app may still run, but it will no longer be supported.
That creates a few practical problems:
For most businesses, the sensible approach is to review Publisher files now, rather than waiting until someone needs an urgent change.
Publisher has often been used for everyday business documents, especially in small businesses, charities, schools, churches & local organisations.
Common Publisher files include:
Even if your business has moved to newer tools, there may still be older Publisher files sitting in shared folders that people forget about until they are needed.
A good first step is to search your business files for anything ending in .pub.
This should include:
Once you know what you have, you can decide what needs to happen next.
Some files may only need exporting to PDF for future viewing or printing. Others may need recreating in a new tool so they can still be edited going forward.
The best Publisher replacement depends on what the file is used for.
For many businesses, the replacement might already be something you have access to.
Word can work well for simple documents, letters, forms, labels, basic flyers & internal templates.
It is familiar, widely used, & already part of Microsoft 365 for most businesses.
PowerPoint is often a better fit for visual layouts, posters, simple one-page designs, signs, certificates & presentation-style documents.
It can be easier than Word when you need to position text, shapes & images more freely.
Canva is a popular choice for social media graphics, posters, flyers, brochures & marketing templates.
It can be useful where non-designers need to create good-looking materials quickly.
Adobe Express can be a good option for quick marketing graphics, branded templates & simple design work.
It may suit businesses that want something more design-focused without moving straight into professional design software.
Adobe InDesign is a stronger long-term option for more advanced design work, larger brochures, print-ready documents, magazines, complex layouts & professional marketing assets.
It is more powerful than Publisher, but also requires more design knowledge.
The problem with older software is rarely the software itself. It is usually the files, processes & “we have always done it this way” habits around it.
A business might not think it relies on Publisher, until someone needs to update an old leaflet, print address labels, change a price list, or reuse a newsletter template.
By checking now, you can avoid the last-minute panic of trying to open a file that is no longer easy to edit.
LVL1 can help businesses review their existing Publisher files, identify what still needs keeping, & work out the best way to move those documents forward.
That might include:
If your business still uses Publisher, or you are not sure whether old .pub files are hiding in your folders, now is a good time to check.
October might feel a while away, but old templates have a habit of becoming urgent at the worst possible time.
