Formats
Three of these keep every sample of your audio. The other four trade a little quality for a much smaller file. Neither is better; they are for different jobs.
Keeps everything
WAV
The studio standard
Use it for masters, for sending to an engineer, and for anything you will edit again.
Keeps everything
FLAC
Lossless, about half the size
Use it for archiving and for sending lossless audio without the size.
Keeps everything
AIFF
WAV's equivalent on Apple systems
Use it when a studio or a label asks for AIFF specifically.
Smaller file
MP3
Plays on absolutely everything
Use it for demos, for email, for anything that has to play anywhere.
Smaller file
M4A / AAC
Better than MP3 at the same size
Use it for Apple devices and for uploads where size matters.
Smaller file
OGG and OPUS
Efficient and open
Use them for streaming, for games and for the web.
What we do not do
A converter should change the container, not the record. This one decodes your file and re-encodes it, and that is the whole job.

Questions
Does converting WAV to MP3 lose quality?
Yes, and it cannot be undone. MP3 discards audio to make the file smaller. At 320 kbps most people cannot hear the difference on most material, but the discarded part is gone. Keep the WAV.
Does converting MP3 to WAV improve it?
No. It makes a large file containing exactly the audio the MP3 had. Useful when a DAW or a distributor insists on WAV, but nothing is restored.
FLAC or WAV for archiving?
FLAC. The audio is identical and the file is about half the size. Use WAV when something in your chain cannot read FLAC.
What bit depth should I choose?
24-bit for anything you will work on again. 16-bit for CD and for final delivery where it is asked for. 32-bit float only if you are moving audio between tools and want no chance of clipping.
Why is my Opus file 48 kHz?
Opus is defined at 48 kHz and nothing else. We resample when you pick it and the result tells you so, rather than doing it quietly.
Will my title and artwork survive?
Wherever the destination format can hold them. MP3, M4A, FLAC and OGG carry title, artist, album and cover art. WAV and AIFF carry far less, so some of it is dropped rather than mangled.
Convert to WAV, MP3, FLAC, AIFF, M4A, OGG or Opus in seconds, with control over bit depth, sample rate and channel count.
The important part is what it does not do: it does not normalise, compress, limit or 'improve' anything. A conversion to a lossless format returns exactly the audio you gave it.
WAV, AIFF and FLAC are lossless: every sample survives, and FLAC simply stores them more efficiently. Converting between these three is reversible and costs you nothing in quality.
MP3, M4A, OGG and Opus are lossy: they discard information to save space. Going from lossy back to lossless does not restore what was removed, so always keep your original master and convert from that rather than from an MP3.
Audio Converter is free. It costs no tokens and there is no cap on how many files you run through it. Create a free account and it is available immediately.
Converting to a lossless format does not change the audio at all. Converting to a lossy format such as MP3 discards some information by design, which is how the file gets smaller. We never apply loudness changes, EQ or limiting during conversion.
Send the highest quality file you have, normally a 24-bit WAV at the session sample rate. Distributors and platforms do their own encoding, and giving them a lossless source produces a better result than sending an MP3.
Yes, it is free and unlimited.
This tool does one job. The engine does the whole record: separation, a mix, a master and the reasoning behind every decision.
Convert cleanly between rates and bit depths.

Split any song into vocals, drums, bass and instruments.
Take the lead vocal out and keep a clean instrumental.
Instrumental plus backing vocals, ready for the screen.
Pull the vocal out on its own, clean enough to reuse.
Pitch correction in the song's own key, natural to hard.

Stereo up to 5.1 or 7.1, and it still folds back down.
Start free, hear the whole thing before you pay a cent, and keep the engineer that learns how you like it.
