Audio Converter FAQ

We support MP3, WAV, FLAC, OGG, AAC, and M4A formats. You can convert between any of these formats using our free online converter.

Yes, our audio converter is completely free with no limitations. No registration, no hidden costs, no file limits. Convert as many audio files as you need.

Absolutely. All processing happens in your browser using WebAssembly technology. Your files never leave your device and are never uploaded to any server.

No, our converter runs entirely in your web browser. Simply visit the page and start converting - no downloads or installations required.

Lossy formats (MP3, AAC, OGG) compress audio by removing some data, resulting in smaller files but some quality loss. Lossless formats (WAV, FLAC) preserve all original audio data but create larger files.

No. Converting from a lossy format (MP3) to a lossless format (FLAC) does NOT improve quality. The audio data lost during MP3 compression cannot be recovered. You will just get a larger file with the same quality.

For perfect quality, use WAV or FLAC (lossless). For a good balance of quality and file size, use MP3 at 256-320kbps. For Apple devices, AAC is a good choice. For web/games, OGG works well.

For music, 192kbps offers good quality for most listeners. Use 256-320kbps for higher quality. For podcasts and speech, 128kbps is usually sufficient.

WAV is uncompressed audio, storing every audio sample without compression. A typical WAV file is about 10MB per minute, while MP3 at 192kbps is about 1.5MB per minute - roughly 7x smaller.

Audio files are typically small and convert in seconds. A 5-minute song usually converts in under 10 seconds on most devices. Larger files or older devices may take slightly longer.

We recommend files under 200MB for optimal performance. Since conversion happens in your browser, very large files depend on your device's available memory.

Currently, our converter processes one file at a time. For batch conversion, you would need to convert each file individually.

Conversion can fail due to corrupted files, unsupported codecs, or insufficient device memory. Try with a smaller file or refresh the page and try again.

Convert MP3 to WAV when you need to edit audio in professional software (DAWs), as many require uncompressed input. Note that this does not improve quality - it just prevents further degradation during editing.

Convert FLAC to MP3 for device compatibility (not all devices support FLAC), to save storage space, or to share music with others who use basic audio players.

FLAC is better for archiving because it is lossless (identical quality to WAV) but 50-70% smaller. Both preserve perfect audio quality, but FLAC saves significant storage space.

Yes, you can convert DRM-free M4A files. However, DRM-protected files from older iTunes purchases cannot be converted directly.
