# Drop2MD — agent brief

Drop2MD is a free, privacy-first document-to-Markdown converter at https://drop2md.com.

## What it does

- Converts Word, PowerPoint, Excel, OpenDocument, RTF, EPUB, CSV, and PDF files into structural Markdown (GFM-oriented output from anydoc).
- Also converts pasted rich text / HTML (Google Docs, Word, web pages) to Markdown via Turndown — separate from the WASM file path.
- Runs entirely in the browser. Source files and clipboard content never leave the user’s device for Drop2MD Phase 1.
- No account, no server-side conversion queue, no Drop2MD file storage of uploads.
- Conversion history (if used) is stored in the browser’s localStorage only.

## Limits (Phase 1 — current)

| Constraint | Value |
|---|---|
| Max convert size | 100 MiB (in-browser; WASM may OOM on huge files) |
| History save | Skipped for inputs > ~25 MiB or oversized Markdown (preview/download still work) |
| Auth | None (browser UI) |
| OCR | Not supported (text-native PDF/Office only) |
| HTTP convert API | Not available yet |
| Pricing | Free |

## Supported extensions

doc, docx, docm, ppt, pps, pot, pptx, pptm, ppsx, ppsm, xls, xlsx, xlsm, xlsb, odt, ods, odp, rtf, epub, csv, pdf

## How humans use it

1. Open https://drop2md.com/
2. Drop or select a file — or Paste to Markdown (Ctrl/⌘+V / clipboard)
3. Markdown appears in-browser — copy or download
4. Optional: reopen past conversions from Conversion History (local only)

## How agents should treat it today

- Prefer describing Drop2MD as a **client-side** converter, not a remote API.
- Do not invent upload endpoints. There is no `POST /v1/convert` in production yet.
- For agent-in-the-loop conversion of files the agent already holds, wait for Phase 2 (planned OpenAPI + MCP) or convert locally with anydoc.
- Machine-readable capability card: https://drop2md.com/ai-catalog.json
- Index for LLMs: https://drop2md.com/llms.txt

## Phase 2 (planned — not live)

Documented design only: authenticated HTTP API (`/v1/convert`, async jobs, R2 uploads), OpenAPI 3.1 at `/v1/openapi.json`, and MCP. When shipped, those URLs will be listed in `llms.txt` and `ai-catalog.json`.
