Audio Tools

Convert, trim, compress, and adjust audio files directly in your browser.

Choosing an Audio Tool

Use the converter to change formats, the cutter to save a range, the compressor to reduce file size, and the merger to join files in order. The iPhone ringtone maker is specialized for M4R output.

MP3, WAV, OGG, and FLAC

MP3 and OGG are lossy formats suited for smaller files. WAV is closer to uncompressed editing audio and is large. FLAC is lossless but often larger than MP3.

Browser Memory

Audio files can expand into large PCM data after decoding. Long FLAC or WAV files may be slow or fail on mobile devices.
