inktomd
Best for: General AI workflows and document conversion.
inktomd strikes the perfect balance for AI use cases. It supports a wide array of formats (PDFs, Word, URLs, YouTube, ArXiv) and optimizes the output specifically for LLMs to save tokens. It is entirely free, requires no signup, and processes files in-memory without storing them.
web2md
Best for: Web article clipping via browser extension.
web2md excels at converting web pages and has a handy browser extension. However, it lacks support for common local file types like PDF and DOCX, and places some features behind a paywall.
Pandoc
Best for: Local, command-line power users.
Pandoc is the undisputed king of universal document conversion, supporting over 40 formats. But it runs on the command line, requires local installation, and its output is standard Markdown — not necessarily optimized for token-saving in AI contexts.
CloudConvert
Best for: Exotic file formats and media files.
CloudConvert supports an incredible 200+ file formats. However, it operates on a pay-per-use basis, stores files temporarily, and treats Markdown as just another format without AI-specific optimizations.
Docling
Best for: Highly structured PDFs and OCR.
Docling is fantastic for deep document understanding, especially complex PDFs with tables and images. However, it supports fewer formats compared to inktomd and can be complex to self-host.
