Your files stay on your Mac.
Converting HTML to Rich Text strips web markup and produces an RTF document that word processors can open directly. Text structure, bold, italic, and heading levels carry over into the Rich Text container. Every file stays on your Mac—conversion runs entirely on-device, no upload required.
Drag one HTML file or an entire folder into Convertessa. Batch mode processes every HTML file in the folder in a single pass, with no file size cap.
Choose Rich Text from the output list, then set quality to control how embedded content is encoded in the RTF output.
Click Convert. Convertessa writes RTF files alongside your originals instantly—no server round-trip, no waiting.
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.

Web-specific markup is removed. Text content and inline formatting—bold, italic, headings—are translated into native RTF constructs that word processors understand directly. No raw tags appear in the output.
Yes. Drop a folder onto Convertessa or run convertessa ./pages --to rtf in the terminal. Every HTML file in the folder is converted in one pass and written to the same directory.
