Frequently Asked Questions

Which format should I pick?

MP3 for universal compatibility and small file size, WAV for uncompressed/editing use, FLAC for lossless compression that's smaller than WAV, OGG for open-source projects, and AAC (M4A) for Apple devices.

Is FLAC actually lossless?

Yes — FLAC compresses file size without discarding any audio data, unlike MP3 or AAC which are lossy formats.

Will converting between lossy formats (like MP3 to AAC) reduce quality?

Converting between two lossy formats can introduce a small amount of additional quality loss, since the audio is decoded and re-encoded — for the best results, convert from your original/highest-quality source file when possible.

Is there a file size limit?

Audio files are generally much smaller than video, so most files convert without any issue.
