Audio Converter

Convert audio files between different formats

Choose Audio File

Supports MP3, WAV, AAC, OGG, FLAC, M4A

Convert audio files between popular formats for compatibility and quality needs. Convert WAV to MP3 for smaller files, MP3 to WAV for editing, FLAC to MP3 for portable devices, or any format to your preferred output. Our tool supports MP3, WAV, AAC, OGG, FLAC, M4A, and more. Choose bitrate and quality settings to perfectly balance file size and audio fidelity. All processing happens locally in your browser using FFmpeg WebAssembly—your audio files never leave your device. Perfect for music conversion, podcast distribution, and high-quality audio archiving.

Audio conversion is the process of changing an audio file's encoding or container format. This typically involves 'Transcoding,' where the original data is decoded and then re-encoded into a new format. There are two main types: Lossy (like MP3 or AAC) which removes data to save space, and Lossless (like FLAC or WAV) which preserves every bit of the original recording. Our tool allows you to perform these complex mathematical operations directly in your browser's RAM, ensuring that your private voice memos or unreleased tracks are never exposed to a third-party server.

Podcasting & Distribution

Convert high-quality WAV recordings to 128kbps or 192kbps MP3s. This ensures your podcast episodes are small enough for quick downloads while maintaining excellent speech clarity for listeners.

Music Library Compatibility

Convert FLAC or ALAC (Apple Lossless) files to MP3 or AAC to ensure your music library is compatible with older car stereos, portable MP3 players, or smart watches with limited storage.

Preparing for Professional Editing

Convert compressed formats like M4A or OGG into uncompressed WAV files. While this doesn't improve the quality, it makes the files easier for Digital Audio Workstations (DAWs) like Audacity or Ableton to process without lag.

Voice Memo Sharing

Convert proprietary voice memo formats from smartphones into universal MP3s, making it easier to share recordings via WhatsApp, email, or Slack without compatibility issues.

Our converter uses a high-performance build of FFmpeg.wasm. (1) The audio file is read into a local buffer via the File API. (2) The engine analyzes the sample rate (e.g., 44100Hz) and bit depth. (3) Based on your selection, the engine applies the LAME encoder (for MP3) or the FDK-AAC encoder. (4) It generates the new file in a local virtual filesystem for immediate download. This 'Client-Side' approach is significantly faster for audio than 'Server-Side' alternatives because it skips the upload and download wait times completely.

Format	Type	Typical Bitrate	Best Use Case
MP3	Lossy	128-320 kbps	General Listening
WAV	Uncompressed	1411 kbps	Editing / Mastering
FLAC	Lossless	Variable (High)	Archiving / Hi-Fi
AAC	Lossy	96-256 kbps	Streaming / Apple
OGG	Lossy	Variable	Gaming / Spotify

This tool is compatible with all modern browsers (Chrome, Firefox, Safari, Edge). Because audio conversion is less CPU-intensive than video, it works exceptionally well on mobile devices. For batch converting many high-resolution FLAC files, a desktop browser is recommended for better memory management.

Frequently Asked Questions

Which audio format is best?

MP3: Universal compatibility, good compression. WAV: Uncompressed, best for editing. FLAC: Lossless compression, audiophile quality. AAC: Better quality than MP3 at same bitrate. OGG: Open source, good quality, used heavily in gaming.

Will converting improve audio quality?

No, converting cannot improve quality - you can't add information that isn't there. Converting a low-quality MP3 to a WAV won't make it sound better, it will just create a larger file. Always start with the highest quality source possible.

Is the conversion private?

Absolutely. All transcoding happens in your browser's local sandbox. Your files are never transmitted to our servers, making this tool perfect for sensitive legal recordings or private voice memos.

What bitrate should I use for music?

For most listeners, 192kbps is the 'sweet spot.' However, for high-quality headphones or home systems, we recommend 320kbps to ensure the highs and lows of the music are preserved without compression artifacts.
