Frequently asked questions

Are my audio files uploaded to a server?
No. All conversion runs locally in your browser using WebAssembly (ffmpeg.wasm). Your files never leave your device — we cannot see them and nothing is ever stored.
What formats can I convert to and from?
Input: MP3, WAV, OGG, FLAC, M4A, AAC, OPUS, AIFF, WEBM, and most other common audio formats. Output: MP3, WAV, OGG, FLAC.
What is the difference between MP3, WAV, OGG, and FLAC?
MP3 is the most widely supported lossy format — small files, plays everywhere. WAV is uncompressed lossless — perfect quality but very large files, used in professional audio. OGG Vorbis is a free open-source lossy format with better quality than MP3 at the same file size. FLAC is lossless compression — identical quality to WAV but roughly half the size, ideal for archiving music.
Will converting audio reduce quality?
Converting to a lossless format (WAV, FLAC) never reduces quality. Converting to a lossy format (MP3, OGG) introduces minor quality loss — use the highest quality setting to minimise this. Converting between two lossy formats (e.g. MP3 → OGG) causes some generation loss; avoid this if possible.
How large a file can I convert?
There's no hard limit — your device's available RAM is the only constraint. Most devices handle files up to a few hundred MB without issues.
Is this audio converter free?
Yes — 100% free, no signup, no account, no watermark, no ads. yhile.com is free forever.
