Structured Markdown output
Convert PDFs into structured Markdown with headings, lists, and reading order preserved instead of a flat text dump. The same conversion engine is used across the browser app, API, and hosted MCP.
PDF to Markdown Converter
PDF to Markdown Converter turns PDFs into structured Markdown for browsers, developers, and AI agents, with anonymous browser conversion plus API and hosted MCP access.
What PDF to Markdown Converter does
PDF to Markdown Converter is a service for turning PDF documents into clean, structured Markdown. It is built for people and agents that need output they can paste into notes, prompts, or documentation instead of a flat text extraction.
The product exposes the same conversion engine through a Chrome extension, a browser-based workbench, a REST API, and a hosted MCP endpoint. That lets a user convert a local file or PDF URL in the browser, while developers and agents can automate the same workflow over HTTPS with API keys.
The source emphasizes preserving document structure: headings, lists, reading order, tables, formulas, links, footnotes, and OCR text from scanned PDFs. It also describes image handling choices, with either embedded base64 images or lightweight placeholders depending on the workflow.
Operationally, the service uses queued jobs with status polling, result download, and slot cleanup. Anonymous conversion is available in the browser surfaces, while API and MCP access use a free Google account to generate bearer keys for paid or automated use.
Core features
Table preservation
Extract tables as real Markdown tables so columns stay readable for people and downstream tools. The product emphasizes preserving document structure rather than reflowing everything into plain text.
Rich content handling
Keep formulas, links, and footnotes intact where possible, and embed images as base64 or replace them with placeholders. This makes the output more usable for editing, review, and LLM prompts.
OCR for scans
Run OCR on scanned and image-only PDFs, including Cyrillic, so non-text documents can still be converted into selectable Markdown. Users can force OCR when needed.
Multiple entry points
Work through multiple surfaces: Chrome extension, web app, REST API, and hosted MCP. The extension and web app can be used anonymously, while the API and MCP use bearer API keys.
Predictable job lifecycle
Create a job, poll status, fetch Markdown, and delete the job when finished. Paid tiers also support webhooks and batch create, which fit automated workflows.
Common ways to use it
Manual conversion in the browser
Use the Chrome extension or web app to convert a PDF into Markdown you can paste into notes, documentation, or an editor. This is the clearest fit when a person wants a quick conversion without building an integration.
Programmatic PDF processing
Send a PDF URL or uploaded bytes to the REST API when you need conversions inside your own application or script. The documented flow is job creation, status polling, Markdown download, and slot cleanup.
Agent tool integration
Connect an agent through the hosted MCP endpoint when you want conversion to appear as a tool inside an MCP-compatible workflow. The hosted MCP uses the same underlying limits and lifecycle as the API.
OCR cleanup for scanned documents
Convert scanned or image-heavy PDFs that need OCR before they are useful in downstream tools. The product highlights selectable Markdown output for scanned documents, including Cyrillic text.
LLM and knowledge-work inputs
Prepare PDF content for LLM prompts, RAG pipelines, or knowledge bases that work better with structured Markdown than with raw PDF text. The product explicitly positions its output for use with ChatGPT, Claude, Notion, Obsidian, GitHub, and similar workflows.
Pros and Cons
Pros
- Preserves structure such as headings, lists, tables, formulas, links, and footnotes.
- Supports OCR for scanned or image-only PDFs, including Cyrillic.
- Available through browser, API, and hosted MCP surfaces.
- Anonymous conversion is available in the browser without sign-up.
- Paid tiers add more capacity, retention, webhooks, and queue priority.
Cons
- The source does not show support for non-PDF input formats.
- Free usage has tight limits on file size, active slots, and document processing time.
- Long documents can be returned partially if they exceed the time budget, with the result flagged as truncated.
FAQ
Do I need an account to convert PDFs?
No. The Chrome extension and web app can be used anonymously for everyday conversion. A free Google account is only needed if you want API keys, hosted MCP, or paid tiers.
How do API keys work?
Sign in with Google, generate an API key, and send it as a Bearer token over HTTPS. The key is a secret you store securely and can revoke later.
What is the hosted MCP?
The hosted MCP is a managed Model Context Protocol endpoint that exposes the conversion workflow as agent tools. It is described as a thin wrapper over the same REST API, so it follows the same slots, limits, and retention rules.
What do paid tiers add?
Paid tiers add more slots, larger file limits, longer document time budgets, longer retention, webhooks, batch create, and higher queue priority.
What file types and outputs are supported?
The service supports PDF conversion to Markdown. The source highlights OCR for scans, real Markdown tables, formulas, images, links, and footnotes, but does not describe support for other input formats.
