What’s Publisher in Microsoft Office 365?

Simple tools make it easy to grab attention with photos

Swap pictures
Import all your pictures to a single canvas in Publisher, and swap them in and out of your design with a simple drag and drop. Experiment to find the right image, without wasting time.

Effects
Use professional-looking effects for text, shapes, and pictures, including softer shadows, reflections, and OpenType features such as ligatures and style alternatives that are familiar to use because they work like the effects in other Office applications that support them.

Online pictures
Use Publisher to search your online albums on Facebook, Flickr, and other services and add pictures directly to the document, without having to save them first to your desktop, laptop, or tablet.

Picture background
Use your photos as high resolution page backgrounds, and make your publications look professional and polished.

Personalize your publications using familiar tools

Mail merge
Include photos and links in the familiar mail merge tools, and boost the personalization of your newsletters, cards, and emails.

Mailings tab
All your personalization needs are in one place—the ribbon.

Publish in the way that suits your audience best

Simplified sharing
Your documents are saved to the cloud by default. You can share and collaborate just by sending a link.

Photo printing
It’s now even easier to print your great-looking publications or photo albums at any print shop with the ability to save all of your pages to a common picture format, such as JPG.

Email
Share a page as an email or send the entire publication in the email message (as HTML)—all the pages will be combined to one message for you.
