Your files stay on your Mac.
Org Mode files are plain-text outlines authored in Emacs — headings, lists, tables, and markup that most word processors can't open directly. Converting to Rich Text Format renders that structure as styled RTF, readable in Word, Pages, LibreOffice, and any RTF-aware editor. The conversion runs entirely on your Mac; your files never leave the machine.
Drag one or more .org files — or an entire folder — onto Convertessa. There is no upload step; everything stays on your Mac.
Pick Rich Text (.rtf) from the output format list. Convertessa maps Org headings, lists, bold, italic, and links to their RTF equivalents.
Click Convert. Each .org file becomes a .rtf file in the same folder, ready to open in any word processor or email client that accepts RTF.
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. Top-level and nested headings become RTF heading styles, and bulleted or numbered lists carry over as RTF list structures. Inline emphasis — bold, italic, underline, and code spans — is also preserved where RTF supports an equivalent.
Yes. Pass the folder path to the CLI (convertessa ./notes --to rtf) or drag the folder onto the app. Convertessa processes every .org file it finds and writes a matching .rtf file alongside each original.
Yes. Convertessa removes embedded metadata — author fields and other file properties — from the output. Document content, structure, and formatting are retained in full.
