About converting audio
Audio formats fall into two camps. MP3 is 'lossy' — it discards inaudible detail to make small files that play on virtually any device, ideal for sharing and storage. WAV is 'lossless' and uncompressed, preserving the exact audio at a larger size, which is handy for editing or archiving.
FileTinker decodes a wide range of inputs (including M4A, AAC, OGG and FLAC, depending on your browser) and exports to MP3 or WAV. Remember that converting an already-compressed file to WAV can't restore quality that was removed earlier — it just stores the same audio uncompressed.
Because the audio is decoded and re-encoded entirely in your browser, your files never reach a server — no upload, no queue, no sign-up.
Frequently asked questions
How do I convert audio to MP3 or WAV?
Add your file, choose MP3 or WAV as the output, and press convert. The converted file downloads when it's done — all in your browser.
What audio formats can I convert from?
Many common inputs are accepted for decoding, including MP3, WAV, M4A, AAC, OGG and FLAC, depending on what your browser supports. Output is MP3 or WAV.
Does converting to WAV improve the quality?
No. WAV is lossless and larger, but converting an already-compressed file like an MP3 to WAV just stores the same audio uncompressed — it can't bring back detail that was already discarded.
Is my audio uploaded to a server?
No. Conversion runs entirely in your browser, so your audio never leaves your device and nothing is stored online.
