How to use Audio Converter

1 Drop your file in the box above, or pick one of the tools below.
2 Each tool runs entirely in your browser — files never leave your device.
3 Adjust the tool-specific options if shown, then click the action button.
4 Download the converted file when it's ready.

Audio formats split into two camps: lossy ones like MP3, AAC and OGG that shrink files by discarding inaudible detail, and lossless ones like FLAC and WAV that keep every bit at the cost of size. Converting between them is about matching the file to where it is going — a podcast, a music library, a voice memo, an editing project. Our free audio converters move between MP3, WAV, OGG, FLAC and AAC entirely in your browser with FFmpeg, no upload and no account. Because nothing is sent to a server, recordings of meetings, interviews and personal voice notes stay private. Adjust the bitrate if you want, convert, and download.

Frequently asked questions

Does converting between audio formats lose quality?

Converting from a lossy format (like MP3) to another lossy format can lose a little quality, because detail already discarded cannot return. Converting to a lossless format (WAV/FLAC) preserves whatever is in the source but will not restore lost detail. For best results, convert from the highest-quality original you have.

Should I pick MP3 or FLAC?

Choose MP3 or AAC when you want small files for phones, streaming and sharing. Choose FLAC or WAV when you are archiving or editing and want full fidelity. FLAC is roughly half the size of WAV for the same quality.

Are my recordings uploaded?

No. Audio is converted locally in your browser, so interviews, meeting recordings and voice memos never leave your device or get stored anywhere.
