AFP vs PDF: What's the Difference?
Both AFP and PDF describe the exact appearance of a page, but they grew up solving different problems. AFP comes from IBM's mainframe and high-volume print world; PDF comes from Adobe and became the universal format for sharing and viewing documents everywhere.
Quick comparison
| AFP | ||
|---|---|---|
| Origin | IBM (mainframe print) | Adobe (universal) |
| Primary use | High-volume transactional print (statements, invoices) | Viewing, sharing, archiving |
| Native viewing | Needs an AFP viewer | Opens almost anywhere |
| Resource reuse | Strong — shared fonts, overlays, images | Usually embedded per file |
| Print streaming | IPDS to production printers | Spooled / rasterized |
Where AFP wins
For producing millions of personalized pages, AFP's reusable resources and record-level indexing are efficient, and IPDS streams pages straight to industrial printers. Electronic overlays let one letterhead or form back thousands of pages without bloating the file.
Where PDF wins
For anything a person needs to open, email, or archive, PDF is unbeatable — every device and browser reads it, and PDF/A is a recognized archival standard. Many print shops generate AFP for the press and a PDF copy for customers.
Converting and viewing
Production pipelines transform AFP to PDF for distribution. To simply look inside an AFP file — its structure and how each page renders — open it in readAFP, which renders AFP to SVG in your browser. It's a viewer and inspector, not a converter. New to the format? Start with what is an AFP file.
