pdftomd

Convert PDFs to Markdown locally in your browser

Productivity·June 2026

pdftomd is a privacy-first, browser-based utility that converts text-based PDFs into clean, structured Markdown (GFM). The Problem Traditional PDF converters require you to upload sensitive documents—such as contracts, proprietary reports, or unpublished research drafts—to external servers, risking privacy leaks. On top of that, raw text copy-pasting strips out document hierarchy, leaving you with broken paragraphs, lost headings, and unstyled lists. The Solution pdftomd performs all processing entirely on your local machine using Google's PDFium engine compiled to WebAssembly (WASM). No files are ever uploaded, ensuring 100% data sovereignty. The local parser analyzes character coordinates and font metrics to reconstruct headers (#), bold weights (**), and bullet lists. Who it is for PKM Users: Obsidian, Notion, and Logseq users who want seamless, structured note imports without manual formatting. AI Developers: Engineers who need clean, semantically coherent text structures for LLM embedding and RAG chunking pipelines. Privacy-Sensitive Professionals: Researchers, academics, and lawyers processing confidential documents that must never touch a third-party server.
