MarkItDown

Description

MarkItDown is an online converter that turns documents into clean, structured Markdown, the format AI tools understand best. It began as Microsoft's open-source MarkItDown utility; this site is an independent service inspired by that project that self-hosts the library behind a simple web workflow, so no Python installation and no account are required to start.

The converter supports a wide range of inputs, including PDF, DOCX, PPTX, XLS/XLSX, HTML/HTM, TXT/MD, CSV/TSV, JSON, XML, EPUB, IPYNB, public URLs, and PNG/JPG/WebP images through OCR. It preserves document structure such as headings, tables, lists, links, and inline formatting, and for scanned PDFs it offers built-in AI OCR that reconstructs content as Markdown, including tables and math equations converted to LaTeX.

You can choose local conversion that keeps supported files entirely in your browser or fast server conversion through the self-hosted engine, where uploaded source files are written only to temporary storage and deleted immediately after conversion. Converted output is ready to feed directly into RAG pipelines, LLM prompts, vector databases, knowledge bases, documentation sites, and Git-based editing workflows.

The free tier handles up to 3 files per batch, files up to 20MB, and 10 OCR pages per month with no account required to start, while a Pro plan raises limits to 100MB files, 30-file batches, unlimited saved results, and 500 OCR pages per month.
