# mdstill

> Free, fast document-to-Markdown converter. Drop a PDF, Word, Excel, PowerPoint, HTML, EPUB, JSON, or one of 18 supported formats and get clean GitHub-flavored Markdown in under a second. Built for LLM prompts, RAG pipelines, and developer workflows.

mdstill is API-first. The web UI at https://mdstill.com runs the same conversion endpoint developers call programmatically. Files are processed in volatile memory and deleted immediately — nothing is stored or used for training. No signup is required for casual use; a free account raises daily quota and per-file size limits.

Output is GitHub-flavored Markdown (.md): tables become pipe tables with alignment, headings map to H1–H6, code blocks stay fenced, and document hierarchy is preserved so retrievers and editors see the structure.
