# pdfbin.net

A free CC0 library of test PDFs. Each PDF lives at a stable flat URL and
is designed to exercise one or more specific behaviors - clean, corrupt
in a known way, encrypted, large, PDF/A conformant, scanned, form-bearing,
shaped like a real document (fax cover, invoice, IRS 1040, ...), or any
combination.

## URL contract

Every PDF lives at https://pdfbin.net/<id>.pdf. Bytes are immutable; the
URL is the version. If a PDF turns out to be wrong, a new ID ships and the
old one stays available, marked status: deprecated in catalog.json.

## Discovery

- /catalog.json - typed catalog: every fixture's facets, sha256,
  page_count, license, lifecycle (added/status/superseded_by)
- /openapi.json - OpenAPI 3.1 spec with every fixture as a GET endpoint

## Conventions

Encrypted PDFs use owner="ownerpass", user="userpass" unless an encrypted
fixture's catalog entry says otherwise.

Total fixtures: 51.
