About Convert Audio
Convert audio between MP3, WAV, OGG, AAC, and FLAC with a bitrate selector, powered by FFmpeg compiled to WebAssembly. Everything happens locally in your browser: nothing is uploaded, stored, or logged. This focused Convert Audio page is designed for musicians, podcasters, students, and editors changing audio format or bitrate for playback and distribution. It opens directly to the working tool, rather than hiding the function inside a general converter or account dashboard.
A WebAssembly build of FFmpeg reads the media from browser memory, runs the selected codec operation on your CPU, and writes the result back to the tab. Your filename and file contents stay on the device. There is no upload queue, temporary cloud copy, account record, or server-side conversion job to delete later. That makes the tool practical for personal records, work material, and drafts that should not be handed to an unknown processing service.
The important limitation is straightforward: The FFmpeg engine downloads once per session (~30 MB) before the first conversion. Knowing that boundary helps you choose the right source file and check the result before relying on it. Processing speed and maximum size depend on your browser and available device memory, which is the honest trade-off for doing the work locally.
FileForge charges nothing for this tool and does not add a watermark. Once the page and its processing engine have loaded, the operation can continue without sending the file over the network. Use the numbered steps below, download the result, and review it before replacing an original file.
