Any document to clean Markdown, in one call

Who it's for

Anyone who has to feed documents to an LLM and doesn't want to host a Python parser for it.

Try it

Paste up to 5 document links (one per line). The three sample files below are real documents hosted here; swap in your own PDF, Word or Excel link.

Limits, plainly

Free and rate limited so it stays fast for everyone. Loop over longer lists 5 documents at a time; a Solo key covers 3,000 calls (up to 15,000 documents) a month.

• Up to 5 documents per call, 10 MB each; 10 calls a minute per IP on the free tier.
• Free tier: 50 calls a day per IP, no key. Paid keys from $19/month (see Get an API key).
• Formats: PDF, Word (.docx), Excel (.xlsx/.xlsm/.xlsb/.xls), OpenDocument (.odt/.ods), Apple Numbers, CSV, HTML and XML. Images and scanned PDFs without a text layer are not converted (no OCR); old Word .doc files need saving as .docx.
• PDF text keeps reading order, but lines inside a paragraph can run together; Word, Excel and OpenDocument tables come out as Markdown tables.
• Documents are converted in memory and never stored. Links must be public http(s) URLs.

Get an API key

Documents to clean Markdown for AI agents and RAG: PDF, Word, Excel, OpenDocument, Apple Numbers, CSV, HTML and XML, by URL or upload, up to 5 per call, with headings and tables kept and a token count. Keys work on the REST API and the MCP server.

Pay with card, Apple Pay, Google Pay or Link through Stripe Checkout (sales tax/VAT handled by Stripe). Your key appears on the page you return to right after checkout: save it. Manage or cancel any time at leafmelt.cybermax-tools.workers.dev/manage. Send it as x-api-key: YOUR_KEY (or Authorization: Bearer YOUR_KEY, which MCP clients support). Check usage at /key. Failed calls are not counted. Document parsers charge per page: Mathpix $5, Reducto $10 and Unstructured $15 per 1,000 pages, LlamaParse from $1.25 (checked 27 Sep 2026). Leafmelt charges per call, not per page, for text documents in 12 formats (no OCR): Solo $19/month for 3,000 calls of up to 5 documents, or $5 pay-as-you-go for 750 calls.

Using several CyberMax APIs? CyberMax API All-Access: one key for all 9 APIs (this one included, 3,000 calls a month here) for $119/month. See All-Access
