Frequently Asked Questions
What formats can I convert?
Input: MP3, WAV, FLAC, M4A, AAC, OGG, Opus, WebM, AIFF, MP4, MOV, MKV, and 3GP. Video files are supported too — only the audio track is extracted and converted. Output: MP3 at 192 kbps or WAV at lossless PCM 16-bit.
What is the difference between MP3 and WAV?
MP3 is a compressed lossy format — roughly one tenth the size of WAV, which makes it perfect for phones, sharing, and streaming. WAV is lossless PCM audio — about ten times larger than an MP3, with no further quality loss, which makes it ideal for editing, mastering, and archiving.
Which should I pick, MP3 or WAV?
Pick MP3 for phones, messaging apps, sharing, car stereos, and anywhere file size matters. Pick WAV when you plan to edit the file in a DAW, master it, feed it into a sampler, or keep it as an archival copy.
Is the audio converter free?
Yes. Completely free. No sign-up, no watermark, no ads, no limits on how many files you can convert. Max file size is 200MB.
Is my file uploaded to a server?
No. The converter runs entirely in your browser using the Web Audio API. Your file never leaves your device — nothing is uploaded or stored anywhere.
What bitrate is the output MP3?
Every MP3 is encoded at a clean 192 kbps — a safe balance of quality and file size that plays cleanly on phones, car stereos, and every MP3 player made in the last 20 years.
What WAV format does it output?
WAV output is lossless PCM 16-bit at the source sample rate. This is the standard WAV format accepted by every DAW, sampler, editor, and mastering tool.
Does the converter work on mobile?
Yes. The converter works on Chrome, Firefox, Safari, and Edge on both desktop and mobile. Drop a file from your phone and download the MP3 or WAV right there.
