About Audio Converter
This online audio converter allows you to convert audio files between different formats directly in your browser. Supports MP3, WAV, OGG, AAC, FLAC, and OPUS formats with adjustable quality settings. All processing happens locally for complete privacy.
What audio formats are supported?
Input: Any common audio format including MP3, WAV, OGG, AAC, M4A, FLAC, OPUS, WMA, and more. Output: MP3, WAV, OGG (Vorbis), AAC (M4A), FLAC (lossless), and OPUS.
Which format should I choose?
MP3: Most compatible, good compression, works everywhere. WAV: Uncompressed, large files, best quality. OGG: Good compression, open source. AAC: Better than MP3 at same bitrate, used by Apple. FLAC: Lossless compression, perfect quality but larger. OPUS: Modern, excellent quality at low bitrates.
What quality setting should I use?
High (320kbps): Best quality, larger files, recommended for music. Medium (192kbps): Good balance, suitable for most uses. Low (128kbps): Smaller files, acceptable for voice/podcasts. FLAC is always lossless regardless of quality setting.
What is the difference between lossy and lossless?
Lossy formats (MP3, OGG, AAC, OPUS) compress audio by removing some data, resulting in smaller files but slight quality loss. Lossless formats (WAV, FLAC) preserve all original audio data. WAV is uncompressed, FLAC is compressed but lossless.
Can I convert FLAC to MP3?
Yes! You can convert between any supported formats. Converting from lossless (FLAC/WAV) to lossy (MP3/OGG/AAC) will reduce file size but some quality is lost. Converting from lossy to lossless won't improve quality.
What is the file size limit?
The maximum file size is 50MB. This ensures smooth processing in your browser.
How long does conversion take?
Conversion time depends on file size and your device. A typical 3-minute song takes 10-20 seconds. Larger files or complex conversions may take longer.
Can I preview before downloading?
Yes! You can listen to both the original and converted audio to compare before downloading.
Is my audio file safe?
Absolutely! All audio conversion happens directly in your browser using FFmpeg.wasm. Your audio file is never uploaded to any server.
