What can you do with Publisher 2021?
Publisher is built for layout-focused print pieces: flyers, newsletters, brochures, menus, business cards and certificates. You place text boxes and images freely on the page, which is harder to do in Word.
Ready-made templates and building blocks speed things up, and mail merge personalises cards or labels. Finished designs can be printed, saved as PDF or packed for a commercial printer.
Publisher 2021 brought a visual refresh and more precise colour choices; the layout tools are the same mature ones long-time users know.
Should I buy Publisher on its own or a full Office suite?
Buy Publisher 2021 on its own if Publisher is the only Office app you need. If you also need several other Office apps, an Office 2021 suite usually makes more sense than separate keys.
| Standalone Publisher 2021 | Office 2021 Professional Plus | Microsoft 365 | |
|---|---|---|---|
| Apps included | Publisher only | Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher | Current Office apps; Publisher is being removed from October 2026 |
| Payment | One time | One time | Monthly or yearly |
| Updates | Security updates until 13 October 2026 | Security updates until 13 October 2026 | New features added regularly |
| Devices | 1 Windows PC | 1 Windows PC | Several devices, including Mac and mobile |
| Best for | You need only Publisher | You use several Office apps | You want the latest features and cloud storage |
A standalone app is the full desktop version, not a cut-down one. Publisher 2021 on its own has the same features as Publisher inside an Office 2021 suite.
What are the system requirements for Publisher 2021?
Publisher 2021 needs a Windows 11 PC with a 1.1 GHz dual-core processor, 4 GB of RAM and 4 GB of free disk space. Microsoft lists the same minimums for the whole Office 2021 family, including standalone apps. There's no Mac version of Publisher.
| Component | Minimum requirement |
|---|---|
| Operating system | Windows 11 |
| Processor | 1.1 GHz or faster, 2 cores |
| Memory (RAM) | 4 GB |
| Storage | 4 GB of available disk space |
| Display | 1280 × 768 resolution |
| Graphics | DirectX 9 or later for hardware acceleration |
| Internet | Needed to download, install and activate |
Microsoft's current requirements list Windows 11, as Windows 10 reached end of support on 14 October 2025.
When does support for Publisher 2021 end?
Microsoft set 13 October 2026 as the end-of-support date for Publisher 2021 and the rest of Office 2021. From that date the app keeps working and stays activated, but it no longer receives security updates.
Microsoft is also retiring Publisher itself: it isn't part of Office 2024, and Microsoft is removing it from Microsoft 365 from October 2026. Installed copies keep working, and Microsoft suggests saving files as PDF or moving projects to Word or PowerPoint, as explained in its Publisher retirement notice. Both apps are part of Office 2024, which Microsoft supports until 9 October 2029.
How do I install and activate Publisher 2021?
Download Publisher with the link in your order email, install it, then enter your 25-character product key when Publisher asks for it. Remove other Publisher versions first, because leftover installs are the most common reason setup or activation fails.
- Uninstall any other version of Publisher, or an Office suite that includes it, from Settings → Apps.
- Download Publisher 2021 using the link in your order email.
- Run the installer and wait until it finishes.
- Open Publisher and enter the product key from your email when asked.
- Check File → Account: it should show “Product Activated”.
A common problem we see is a clash with Office that's already on the PC. Microsoft doesn't support two Click-to-Run installations that contain the same app, so Publisher 2021 can't sit next to Microsoft 365 or another Office version that already includes Publisher. An older MSI-based install such as Office 2016 can also block setup, so remove it first.
Frequently asked questions
What happens to my Publisher files when support ends?
Your .pub files keep opening in Publisher 2021 on your PC. Because Microsoft is retiring Publisher, it recommends saving important files as PDF through File → Save As. A PDF can then be opened in Word if you want to keep editing there, though the layout may shift.
What happens to Publisher 2021 after 13 October 2026?
Publisher 2021 keeps working and stays activated, but Microsoft no longer releases security updates for it from that date. For a PC that handles email or sensitive files, we suggest a supported version such as Word or PowerPoint 2024, which gets updates until 9 October 2029.
Can I move Publisher to a new PC later?
This key is for one PC. If you replace your computer, contact our support team with your order number before you uninstall from the old PC. Whether a transfer is possible depends on the licence type, so it's best to ask first.
Do I need Office installed to use Publisher 2021?
No. Publisher 2021 is a complete standalone app and installs on its own, without any other Office app. If the PC already has a different Office version that includes Publisher, remove it first, as explained in the installation section above.
Browse all standalone Office apps, or get Publisher together with Word, Excel and more in Office 2021 Professional Plus.
