About - pdfbin.net

pdfbin.net is a free CC0 library of test PDFs you can drop into your test suite. Every PDF lives at a stable flat URL; bytes are immutable; multi-axis typed metadata lives in catalog.json.

Why this exists

The practice for “I need a sample PDF for my test suite” today is: find a PDF on GitHub, right-click save into the repo, pray it stays addressable. pdfbin.net replaces that with:

• Flat immutable URLs
• Explicit CC0 licensing
• A typed multi-axis catalog
• Real corruption / encryption / scan / document-shape variants

URL contract

Every PDF is served at https://pdfbin.net/<id>.pdf. The bytes never change. If a PDF turns out to be wrong, a new ID ships and the old one stays available, marked status: deprecated in catalog.json.

Who built this

pdfbin.net is built and maintained by mintfax - a developer-first fax API. Mintfax’s sandbox documentation points at these PDFs; making the catalog public costs us nothing and spares everyone else the right-click-save-from-github dance.
