.AFPUB File Extension

Serif released Affinity Publisher in 2017 to replace PagePlus, and to accommodate their Affinity Photo and Affinity Designer applications. Graphic designers use Affinity Publisher to create printed and online documents, such as magazines, brochures, flyers, books, brand guidelines, and manuals. The software includes many tools that allow graphic designers to place, align, and adjust images and text, as well as add additional, layer-based graphic design elements.

When a graphic designer saves an Affinity Publisher project, the project is saved as an AFPUB file. The AFPUB file contains all the information needed to re-open the project in Affinity Publisher, including a record of the edits the graphic designer has made to the project. That way, the graphic designer can undo or adjust their edits in the future.

NOTE: Serif replaced PagePlus with Affinity Publisher in 2017.

How to save an AFPUB file as a package

AFPUB files often contain links to images and other assets included in a page layout project. If you want to avoid preserving links to the assets included in an AFPUB file, you can save the project as a package, which will automatically create copies of all linked assets and store them alongside your AFPUB file. To save an AFPUB file as a package, select File → Save As Package... from Affinity Publisher's menu bar.
