Browser-based document conversion
Convert supported files directly in the browser, then copy the Markdown or download it as a .md file.
t0md
t0md converts PDFs, Word, PowerPoint, HTML, and JSON to Markdown for browser users and MCP-compatible AI agents. Free browser flow, API, and remote MCP server.
Overview
t0md is a document-to-Markdown converter for people and AI agents. It accepts PDFs, Word documents, PowerPoint files, HTML, and JSON, then returns clean Markdown that can be copied, downloaded, or passed into an MCP-compatible workflow.
The product is designed for a browser-first conversion flow and a developer-facing agent workflow. The homepage says uploads are converted in memory and discarded, while the MCP page documents a remote server for Claude Code, Cursor, Windsurf, Hermes, OpenClaw, VS Code with MCP extensions, and Continue.dev.
Features
Multiple document formats
The site supports PDF, Microsoft Word, HTML, PowerPoint, and JSON today, with EPUB, XLSX, image OCR, and URL conversion marked as coming soon.
In-memory handling
Files are converted in memory and discarded, so the product does not keep uploaded documents after processing.
Agent workflow via MCP
An MCP server lets Claude Code, Cursor, Windsurf, Hermes, OpenClaw, and other MCP-compatible agents convert documents mid-conversation.
MCP transport and upload support
The MCP server exposes both streamable-HTTP and legacy SSE transports, plus a file-upload endpoint for large documents.
API-backed conversion output
The API returns JSON with markdown, filename, pages, and bytes, and the MCP server wraps the same conversion endpoint.
Use cases
Turn dense documents into editable text
Convert a research paper, report, or contract into Markdown so it can be searched, quoted, and edited in plain text tools.
Use documents inside an AI workflow
Send a document to Claude Code, Cursor, or another MCP-compatible agent and keep working in the same conversation while the agent converts it.
Publish notes and drafts in Markdown-first tools
Move converted content into Obsidian, Notion, Bear, or a GitHub README without copy-paste cleanup or formatting loss.
Version documents in git
Use Markdown output in git-based workflows to compare revisions, track changes, and review document diffs more easily than with PDFs.
Automate conversion for applications and agents
Use the API or MCP upload endpoint when you need programmatic conversion or want to avoid base64 payloads for larger files.
Pros and Cons
Pros
- Supports several common document formats in a single conversion flow.
- Offers both a browser upload experience and an MCP server for agent workflows.
- States that uploads are handled in memory and discarded after conversion.
- Provides a simple output path: copy Markdown, download .md, or consume JSON through the API.
- Includes streamable-HTTP and legacy SSE transport options for different MCP clients.
Cons
- The site only documents a partial set of file types today; EPUB, XLSX, OCR, and URL conversion are still listed as coming soon.
- Tables and complex layouts are described as best effort rather than guaranteed.
- The pricing page is not available, so detailed plan information is not published on the site.
FAQ
How do I convert a document to Markdown?
Drop a supported file on the homepage upload area, or send it to the MCP server from an AI client. The browser flow converts the file and lets you copy the Markdown or download a .md file.
Which file types are supported?
PDF, Microsoft Word, HTML, PowerPoint, and JSON are live today. EPUB, XLSX, image OCR, and URL-to-Markdown are listed as coming soon.
How clean is the Markdown output?
Headings, lists, and paragraph breaks are preserved. Tables and complex layouts are handled best effort, so output quality depends on how structured the source document is.
Are files stored after conversion?
Uploads are converted in memory and discarded after conversion. The site says files never leave your browser session, and temporary MCP download links expire after 10 minutes.
Is t0md free to use?
The homepage says the browser conversion is free and will stay free. The MCP server is free for now, with possible paid tiers later for high-volume API and MCP traffic.
