PrivateRemix — Private local media converter

How it works

Three steps. Zero uploads.

The same flow every time — sensible defaults, with size and quality controls when you want them.

1

Drop a file

Drag any file into PrivateRemix, or pick one from your Mac.

2

Pick a format

PrivateRemix shows you everything that file can become, and why.

3

Convert locally

The new file appears next to the original. Nothing leaves your Mac.

Everything stays on this Mac

Built private, not bolted-on.

Most “free online converters” are upload services. PrivateRemix has no server to upload to.

Everything runs locally

Every conversion uses your Mac's own processor. Your files are never uploaded to a server.

No cloud, no AI

Deterministic on-device engines only. Nothing is sent to the cloud or to any AI service.

Works offline

PrivateRemix never needs the internet to convert a file. Disconnect entirely — it still works.

No account, no tracking

No sign-in, no analytics, no ads. When you quit, the app remembers nothing.
