Your files stay on your Mac.
An OGV file is an Ogg video container carrying both video and audio tracks. Converting it to Ogg Vorbis extracts the audio stream and re-encodes it as a standalone .ogg file. Set quality to balance fidelity against file size — all processing happens on your Mac with no upload required.
Drag one or more .ogv files into Convertessa, or point the CLI at a folder to queue an entire batch at once.
Choose Ogg Vorbis from the output list. Set quality to control the trade-off between audio fidelity and output file size.
Convertessa extracts and re-encodes each audio stream locally. The resulting .ogg files are ready when the progress bar clears.
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.
Read the full CLI documentation →Shrink Convertessa down to a small, focused window — drop, convert, done, with your recent conversions one click away.

New formats, new features, and fixes — every release, on the record.
Higher quality preserves more of the original audio at the cost of larger files. For voice recordings a mid-range setting is usually sufficient; for music or high-fidelity content, push it higher. Convertessa lets you set quality before each conversion run.
Yes. Drop the folder onto Convertessa or run convertessa ./folder/ --to ogg in the terminal. Every .ogv file in the folder is converted in one pass.
No. Ogg Vorbis is an audio-only format, so the output .ogg file contains just the audio stream extracted from the original .ogv container. The video track is not carried over.
