Your files stay on your Mac.
DVD VOB files bundle video, audio, and subtitle streams into disc-image containers that most players and editors cannot open directly. Converting to MPEG unpacks that stream into a widely supported video file you can play, share, or import into any editing tool. The conversion runs entirely on your Mac — no upload, no cloud, no waiting.
Drag one file or an entire DVD folder into Convertessa. Batch mode processes every VOB in the folder in one pass.
Choose MPEG from the output format list. Adjust quality to balance file size and playback fidelity — MPEG is lossy, so higher quality means a larger file.
Click Convert. Convertessa writes the MPEG files to your chosen destination folder — nothing leaves your Mac.
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. Drop a folder containing multiple VOB files onto Convertessa and it converts every file in one batch, outputting a separate MPEG for each.
MPEG is a lossy format. A higher quality setting preserves more detail at the cost of a larger file; a lower setting shrinks the file but introduces more compression artifacts. Convertessa lets you set quality before converting so you control the trade-off.
No. Convertessa runs entirely offline on your Mac. Your VOB files are never uploaded to any server — conversion happens locally and the resulting MPEG files stay on your machine.
