A lightweight, open-source tool for compressing, converting, and enhancing audio — no uploads, no cloud processing, no limits.

Why SoundWich?

Editing and converting audio shouldn’t require heavy software, lengthy uploads, or subscriptions. SoundWich makes it simple — everything runs locally in your browser, with full control over quality and format.
