Your files stay on your Mac.
Converting a PDF to Markdown reads the document's text and structure — headings, paragraphs, and lists — and writes them as plain .md syntax. The result is a lightweight, version-control-friendly file you can open in any editor or paste straight into a static site generator. Every file stays on your Mac; nothing is uploaded.
Drag a single PDF or an entire folder into Convertessa. Batch mode queues every PDF at once so you don't have to repeat the process file by file.
Pick Markdown from the output list. Convertessa will write one .md file for each PDF, using the same base filename.
Click Convert. Your Markdown files appear alongside the originals. No internet connection required — conversion runs fully offline on your Mac.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
Pick a format you have — see everything Convertessa can turn it into.

No cloud. No account. No upload. Every conversion happens entirely on-device, using the power already in your Mac. What you convert is nobody’s business but yours.
Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.

New formats, new features, and fixes — every release, on the record.
Convertessa maps the PDF's structural elements — headings, paragraphs, and bullet lists — to their Markdown equivalents. Output quality depends on how the source PDF encodes its text; PDFs made up entirely of scanned images contain no extractable text and will produce minimal output.
Yes. Pass a folder path on the command line (convertessa ./docs/ --to md) and Convertessa processes every PDF in that folder, writing a .md file for each one.
Yes. Convertessa removes embedded metadata from the source document during conversion, so the output Markdown file carries no hidden author or creation details from the original PDF.
