Show HN: MarkdownConverters – Convert any file format to clean Markdown

Hey HN

I built MarkdownConverters.com — a tool that converts any file format (PDF, DOCX, PPTX, HTML, or URL) into clean, structured Markdown.

I often needed to prep documents, reports, or scraped pages for AI pipelines, documentation, or version control, but existing tools either broke formatting, lost code blocks, or produced unreadable Markdown.

So I built something that focuses on: • Accurate structure (headings, lists, tables, code, links) • Consistent Markdown output ready for LLMs or docs • Fast, browser-based conversion with privacy-friendly processing • Support for multi-format and URL inputs

It’s especially useful if you work with RAG, embeddings, or text preprocessing — Markdown becomes a universal “clean” format for structured content.

Would love feedback on: • Conversion quality — what edge cases break for you? • Formats you’d like supported next (CSV, EPUB, JSON, etc.) • API workflows — would you use it for automation?

Happy to answer any technical questions about the conversion pipeline or file parsing methods.
