This free online audio converter changes MP3, WAV, M4A, AAC, OGG, FLAC, and WebM audio into the format you need. Control the bitrate, sample rate, and mono or stereo channels, then preview the converted file before downloading it.
Conversion happens locally with FFmpeg WebAssembly. Your audio never leaves your device, so there is no server upload, account, waiting queue, or watermark.
For compressed formats, a higher bitrate generally keeps more detail but creates a larger file. 128 kbps is a practical default for speech and casual sharing, while 192–320 kbps may suit music. A 44.1 kHz sample rate is standard for music; 48 kHz is common for video. Mono can reduce the size of speech recordings, while stereo preserves separate left and right channels.
Need only part of the file? Open the audio trimmer and MP3 cutter. To convert a video soundtrack, use Extract Audio from Video.
Choose the WAV file, select MP3 as the output, pick a bitrate, and select Convert Audio. A lower bitrate creates a smaller MP3; a higher bitrate retains more detail from the source.
Inputs include MP3, WAV, M4A, AAC, OGG, FLAC, and WebM audio. You can export MP3, WAV, M4A, AAC, OGG, or FLAC.
It depends on the goal. Choose MP3 for compatibility, M4A or AAC for efficient compressed audio, WAV for uncompressed editing, FLAC for lossless storage, or OGG for an open web-friendly format.
No. A higher output bitrate cannot restore detail already removed from a compressed source. It can only reduce additional loss during the new encode, usually at the cost of a larger file.
The bitrate presets apply to lossy compressed formats. WAV uses uncompressed PCM, while FLAC uses lossless compression; their sizes depend mainly on duration, sample rate, channels, and bit depth.
Yes. The selected file is read and converted on your device. It is not uploaded to or stored by RizCraft.
You can select an audio file up to 500 MB. Browser memory may limit very long or high-resolution files on lower-powered devices.
