Hvad er AFPUB-filformatet?
En .afpub-fil er det oprindelige dokumentformat til Affinity Publisher, den desktop publishing-app, som Serif har bygget som et alternativ til Adobe InDesign. Serif udgav første gang Affinity Publisher i juni 2019, og Canva opkøbte virksomheden i 2024.
En enkelt .afpub-fil indeholder en hel publikation. Det inkluderer side- og opslagsgeometri, mastersider, lag, tekstrammer og deres typografier, tabeller, vektorformer og rasterbilleder, der enten er integreret i filen eller linket fra disken. Affinity gemmer også dokumentets tilstand, så genåbning af en fil gendanner layoutet præcis, som det blev forladt. Designere bruger .afpub-filer til brochurer, magasiner, bøger, flyers og plakater.
Formatet er proprietært. Serif har aldrig offentliggjort specifikationen, hvilket er grunden til, at intet pålideligt tredjepartsprogram kan læse .afpub direkte.
Sikkerhed og tryghed
RISIKO: LOWAn .afpub file is a document, not an executable, so it carries little inherent risk. It can contain embedded images but no macros or scripts that run on open. As always, only open files from sources you trust, since large embedded assets can make files very big.

| Notes | In October 2025 Canva unified the Affinity apps into a single free application that introduced a new universal .af format. The classic Affinity Publisher 2 apps continue to open and save .afpub files; the new unified app can open .afpub but its own .af files cannot be reopened in the older version-2 apps. |
