Your files stay on your Mac.
Convertessa reads your .textile files and rewrites them as roff-formatted man pages, replacing Textile headings, lists, and emphasis with the .TH, .SH, .B, and .I macros that man(1) expects. The output opens directly in any Unix terminal via man -l or groff. Every file stays on your Mac — nothing is sent to a server.
Drag one .textile file or an entire folder into Convertessa. The app reads Textile markup — headings, paragraphs, lists, bold, italic, and inline code.
Choose Man Page (roff) from the output list. Convertessa maps each Textile construct to its roff equivalent: headings become .SH macros, emphasis becomes .B and .I, and code spans become \fC sequences.
Click Convert. Convertessa writes .man files locally alongside your originals or into a chosen destination folder. Open them with man -l output.man or pipe through groff to produce PostScript or PDF.
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.
No. Convertessa converts entirely offline. Your .textile files are read and written locally — no network request is made at any point.
Yes. Pass the folder path on the command line (convertessa ./docs/ --to man) or drag the folder into the app to batch-convert every .textile file inside in one pass.
Headings become .SH (and .SS for sub-sections), bold becomes .B, italic becomes .I, bulleted lists become .IP \(bu items, and code spans use \fC/\fR font escapes. The opening .TH macro is derived from the first h1 in the file.
