This converts PDFs to structured Markdown while preserving headings, tables, and lists instead of dumping flat text. It's built on Nutrient's CLI tool and handles both single files and batch directory processing. The batch mode runs conversions in parallel, which matters if you're processing more than a handful of documents. You can optionally extract images too. The main thing to know is it writes output to disk and doesn't auto-load it back into context, which is the right default since converted PDFs can be huge. Free up to 1,000 documents per month, then you need a commercial license.
