Frequently Asked Questions
Everything people ask before using convert audio.
Use MP3 or AAC for the smallest files that still sound good — ideal for phones, podcasts and sharing. Choose WAV or FLAC when you need lossless audio for editing or archiving, and OGG for efficient open-source playback.
No. Converting a compressed file to a lossless format cannot restore detail that was already discarded. It is useful when a program demands WAV input, but the audio itself will sound the same as the MP3 you started with.
192 kbps is a good default for music, 128 kbps is fine for spoken word and podcasts, and 320 kbps is the highest quality MP3 you can get. Higher bitrates produce larger files.
No. AudioKit processes every file locally in your browser using WebAssembly. Your audio is never transmitted to a server, never stored, and never seen by anyone but you. You can even disconnect from the internet after the page loads and the tools keep working.
You can open MP3, WAV, OGG, FLAC, AAC and M4A files. Output formats depend on the tool — Convert Audio can write MP3, WAV, OGG, FLAC, AAC and M4A.
