What is a .afpub file?
AFPUB is a document from Affinity Publisher, Serif’s page-layout app. Created and opened by Affinity Publisher.
- Did you know
- Affinity Publisher was the last of Serif’s three Affinity apps to arrive, completing the suite in 2019.
- Serif was bought by Canva in 2024, and a year later Publisher was rolled into a single free Affinity application.
- Affinity Publisher's StudioLink lets you switch into the Photo and Designer toolsets inside the same document, folding photo-editing and vector tools into a page-layout app.
- What Analyser reads
- Identify design-app files: Figma (FIG), Sketch, Affinity Photo/Designer/Publisher, GIMP (XCF), CorelDRAW (CDR), MediBang Paint (MDP) and Substance. Krita (KRA), Procreate and Paint.NET (PDN) now show their embedded preview - see Raster art above.
- Depth of analysis
- .afpub is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .afpub file
- Drag a .afpub file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
