Your files stay on your Mac.
Convertessa reads your .md files — headings, paragraphs, code blocks, and all — and renders them into a PDF document entirely on your Mac. Nothing is uploaded; files never leave your machine. Convert a single note or an entire folder of Markdown files in one pass.
Drag one or more .md files onto the Convertessa window, or pass them directly on the command line.
Pick PDF from the output format list. Set quality to control how embedded images are compressed in the output file.
Click Convert. PDF files appear beside your originals with metadata stripped.
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.
Convert hundreds of files at once with per-type group defaults and individual overrides.
First-class support for HEIC, AVIF and WebP — encode and decode, both ways. Read JPEG XL and a dozen more modern formats too.
Drop files anywhere on the window. Native, instant, and exactly what you’d expect on a Mac.
Dial in compression, resolution and bitrate. Keep originals pristine or shrink for sharing.
Never overwrite a file by accident. Convertessa appends safe suffixes automatically.
Every job is logged locally. Re-run a previous conversion or revisit recent outputs in a click.
Bundle your converted files straight into a single ZIP, TAR or 7z — packaged and ready to share the moment a job finishes.
Right-click any file in Finder and choose Convert. A Quick Action handles it on the spot — no need to open the app first.
Shrink Convertessa to a tidy mini window that tucks into a corner — just a drop zone and a format picker for quick, one-off conversions.
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.
Yes. Convertessa renders your Markdown syntax — headings, paragraphs, lists, and code blocks — into the PDF output. The conversion runs entirely on your Mac; no internet connection is required.
Yes. Pass a folder path with convertessa ./docs/ --to pdf and Convertessa processes every .md file inside it. You can also drag a whole folder onto the app window.
No. Convertessa strips document metadata from the output, so author information or editor metadata embedded in the source file will not carry over into the PDF.
