pdfmarkdown.app turns any PDF into clean, AI-ready Markdown — and it goes both ways. Everything runs in your browser, so your file never leaves your device. No signup, no upload, free.

Most converters turn a PDF into messy text: tables collapse, formulas break, figures vanish. pdfmarkdown.app is built around fidelity — the things that usually break come through intact:

• Tables stay as real Markdown tables
• Formulas render as real math (LaTeX)
• Images / figures are kept, not dropped
• Reading order and structure are preserved

See it before you trust it

You get the original PDF and the converted Markdown side by side, and the pages it couldn't read cleanly are flagged instead of faked — so you can trust the output before pasting it into Obsidian, your notes, or an AI tool.

Both directions

It also works the other way: paste or write Markdown → export a polished PDF.

Who it's for

People who live in Markdown — Obsidian and PKM users, researchers, and anyone prepping documents for RAG, ChatGPT or Claude.

Why it's different

• Browser-only — your file is never uploaded (private by default)
• Free, no signup
• Bidirectional — PDF → Markdown and Markdown → PDF
• Honest about what it can't do, instead of silently mangling it

A cutlist is a list of parts and dimensions needed for a project, cut from sheet or linear material. Cutlists can be generated manually or automatically with software like Sketchup. Cutlist optimization reduces wasted material, often done with automated software. Efficient algorithms balance speed and ease of cutting. Cutlist Evolution is a tool that calculates optimized cutlists, balancing efficiency and time taken. Optimizing cutlists is a complex challenge known as the 'stock cutting' problem, often requiring computing power and various approaches. Cutlist Evolution achieves over 90% efficiency reliably in tests.
