Input: MP3, WAV, M4A/AAC, OGG, FLAC and WebM, depending on your browser. Output: MP3, WAV or FLAC at 44.1 kHz. WAV/FLAC use 16-bit PCM. M4A and OGG export are not offered.

Higher bitrate cannot restore lost detail. FLAC preserves the processed PCM, not the original compressed file. Normalization and gain alter the signal; automatic gain reduction prevents clipping. Metadata and album art are not copied.

What are the limits of Audio Converter?

20 MB per input, 80 MB combined, five minutes each and 80 MB combined output. Browser decoding varies. All output is 44.1 kHz; WAV/FLAC use 16-bit PCM. No M4A/OGG export, DRM bypass, metadata preservation or recovery of lost detail. FLAC is lossless relative to processed PCM. Larger conversions may strain mobile memory.
