What it does

From terminal docs to wiki markup

Man pages store documentation in roff/troff markup — a format built for terminal rendering, not collaborative wikis. Convertessa parses the roff source and emits MediaWiki markup so your command-line documentation can live alongside the rest of your wiki. Section headings, bold, italics, and code spans all transfer without manual reformatting.

How it works

Three steps. No upload required.

1

Drop your Man Page (roff) files

Drag one .man file or an entire folder onto Convertessa. All files are processed locally — nothing is uploaded.

2

Choose MediaWiki

Choose MediaWiki from the output format list. Convertessa maps roff section macros to MediaWiki headings and inline markup to wiki syntax.

3

Convert

Click Convert. Each man page becomes a .wiki file ready to paste into any MediaWiki installation.

Format catalog

From everyday files to pro media.

Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.

Features

Built for real work.

Batch conversion

Convert hundreds of files at once with per-type group defaults and individual overrides.

Modern image formats

First-class support for HEIC, AVIF and WebP — encode and decode, both ways. Read JPEG XL and a dozen more modern formats too.

Drag & drop

Drop files anywhere on the window. Native, instant, and exactly what you’d expect on a Mac.

Quality control

Dial in compression, resolution and bitrate. Keep originals pristine or shrink for sharing.

Collision-safe naming

Never overwrite a file by accident. Convertessa appends safe suffixes automatically.

Conversion history

Every job is logged locally. Re-run a previous conversion or revisit recent outputs in a click.

Archive the output

Bundle your converted files straight into a single ZIP, TAR or 7z — packaged and ready to share the moment a job finishes.

Convert from Finder

Right-click any file in Finder and choose Convert. A Quick Action handles it on the spot — no need to open the app first.

Compact mode

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.

Your files never leave your Mac.

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.

On-device processing Zero telemetry No file uploads
For power users

There’s a command line, too.

Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.

FAQ

Good questions.

Convertessa is a native macOS app that converts your files between formats — images, audio, video, documents, archives and eBooks — entirely on your Mac. Drop a file in, choose an output, and it’s done. No uploads, no account, no subscription.
Convertessa is an orchestrator. Under the hood it relies on best-in-class open-source engines — FFmpeg for audio & video, Pandoc for documents, libvips for images, LibreOffice for office formats, and Calibre for eBooks. It installs them for you with a click, then calls the right tool, or chain of tools, in the right order for whatever you’re converting. You get one clean native interface instead of a tangle of command-line flags. These binaries aren’t bundled with the app and are never installed without your approval — Convertessa simply calls them in a terminal session on your behalf.
Popular ones include JPEG, PNG, HEIC, WebP and AVIF; MP3, AAC, FLAC and WAV; MP4, MOV and MKV; PDF, DOCX and EPUB; ZIP, TAR and 7z — and many more. See exactly what converts to what in the conversion explorer →
Email us and we’ll add it in an upcoming release. Convertessa’s format coverage grows with what people actually need, so your request genuinely helps shape the app.
Your files? Never. Every conversion happens locally on your Mac. Your files are never uploaded, and nothing you convert is ever sent anywhere. Our Privacy Policy spells out exactly what limited data the app does store.
No analytics, no tracking, no telemetry. Your files and conversions stay entirely on your Mac — nothing you convert is ever sent anywhere. The app periodically checks for software updates in the background; like any web request, that check reveals only standard request metadata (your IP and app/OS version) to our update server — never your files, name, email, or license — and updates are always user-approved. Our Privacy Policy spells out exactly what’s stored — and what isn’t.
Yes. Convertessa is a universal app and runs natively on Intel Macs. It requires macOS 14 or later.
Yes. It’s tuned for Apple Silicon (M-series) and runs natively — fast and energy-efficient. macOS 14 or later.
Yes — your license works on an unlimited number of your own Macs. Buy once and install it everywhere you work.
You get a genuinely useful, private, native Mac app for a single $19 payment — no subscription, ever. And your purchase directly supports a small independent developer and the app’s ongoing updates and new formats.
There’s no separate trial, but every purchase is backed by a 14-day money-back guarantee. If Convertessa isn’t right for you, contact your payment processor within 14 days to request a full refund — no questions asked. You can also email us and we’ll help route it.
Quite possibly — just email us. If you’re a student, run a non-profit, or have another good reason, reach out and we’ll sort you out.
Convertessa was built by Daler Azimov — a developer who needed a fast, private, native file converter for his own work, and decided to make the one he wished existed. Connect on LinkedIn →

Convertessa covers the most common man-page macro sets including .SH, .SS, .TP, .PP, .B, .I, and .EX/.EE code blocks. Roff constructs with no MediaWiki equivalent are stripped cleanly rather than left as raw markup.

Yes. Drop a folder of .man files onto Convertessa and it processes all of them in one pass, producing one .wiki file per source document.

No. Convertessa strips metadata from the output. The resulting MediaWiki files contain only the converted markup.
