Everything you need to know about format extraction, privacy, and markdown compatibility.
Pandoc is an AST-to-AST document compiler designed for structured text formats (Markdown, LaTeX, DOCX, HTML). When converting PDFs, Pandoc cannot parse PDF vector coordinate streams natively; it delegates to external utilities like `pdftotext`, which flatten 2D spatial coordinates into unstructured text streams, breaking tables and math formulas.
No. While Pandoc requires a local CLI installation, Haskell runtime packages, and Poppler dependencies, our tool runs 100% inside your browser using WebAssembly. There is zero installation, zero package management, and zero environment setup required.
Pandoc dumps PDF math as disconnected Unicode symbols or raw strings. Our engine reconstructs mathematical ASTs into standard KaTeX/MathJax delimiters (`$...$` and `$$...$$`).
Yes! Our standalone CLI tool (`pdftomarkdown input.pdf -o output.md`) provides a drop-in command-line alternative that produces significantly cleaner GFM Markdown than Pandoc.
