Your files stay on your Mac.
DTS is a compressed surround-sound format used in Blu-ray discs and home-theater rips. Converting to WAV unpacks the encoded audio into uncompressed PCM — a format every DAW, editor, and media player reads without plug-ins. Your files never leave the Mac: no upload, no cloud, no waiting.
Drag a single file or an entire folder into Convertessa. Batch mode picks up every DTS file in the directory and queues them all at once.
Select WAV from the output format list. Convertessa decodes the DTS stream and writes standard uncompressed PCM WAV — no extra settings required.
Click Convert. WAV files are written to your chosen destination, ready for your editor, archiver, or media player.
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.

No. WAV stores audio as uncompressed PCM, so the decoded DTS signal is written without further lossy encoding. The output is a bit-accurate representation of what was inside the DTS stream.
Yes. Drag the folder into Convertessa or run convertessa ./folder --to wav in Terminal. Every DTS file in the directory is converted in a single pass.
Convertessa decodes the DTS stream as-is and writes the channels into the WAV container. The channel count from the source DTS file is retained in the output.
