PDF to Markdown for Developers — API Docs & Specs
Most engineering teams have a graveyard of PDF specs — internal RFCs, vendor API references, design documents — that nobody reads because nobody can search them. Converting to Markdown makes the whole thing live: greppable, diffable, reviewable in PRs, indexable by your AI coding assistant.
Why this is hard without the right tool
- Vendor API documentation lives only as PDF
- Internal specs are PDF attachments on Jira tickets — never read after the ticket closes
- Cursor/Copilot/Claude Code can't use PDFs as workspace context
- Searching across 50 specs requires opening each one
- PRs that reference specs link to PDFs that change without anyone noticing
Recommended workflow
- Convert each PDF spec to Markdown via web UI or API
- Commit the .md files to
docs/in your repo - Reference specs from code comments using relative paths
- Let your AI coding assistant index the Markdown alongside source code
- Re-convert and commit when vendors publish new versions — Git diff shows what changed

The API uses Bearer token authentication...Frequently asked questions
How do I integrate converted docs into Cursor or Copilot?
Drop converted .md files into your workspace under <code>docs/</code>. Both Cursor and Copilot index the workspace and surface Markdown content as context when you ask questions or generate code that references the documented APIs.
Can I keep PDFs and Markdown in sync via Git?
Convert on every vendor release, commit the .md, let Git track the diff. <code>git log --follow docs/vendor-api.md</code> then shows you exactly what changed between versions of the spec — far more useful than diffing PDFs (which Git treats as opaque binary).
What about API specs in OpenAPI/Swagger format?
Those are already structured — convert them with a dedicated OpenAPI tool, not ours. Our converter is for human-prose specs delivered as PDF. The two workflows complement each other.
How do I link from code comments to converted docs?
Relative paths from your source file: <code>// See docs/vendor-api.md#authentication</code>. Cursor and Claude Code follow these references automatically when generating code.
Best practice for diff review on doc updates?
Treat doc PRs like code PRs — run <code>diff</code>, look at the rendered output, ask "is this change intentional?". When the diff is large or unclear, our re-conversion may have shifted formatting; spot-check the corresponding section of the new PDF.
