Convert Audio Files Online
Turn audio into MP3, WAV, FLAC, AAC or OGG with a quality you control. The conversion runs entirely in your browser — the file never leaves your device.

This audio converter turns files between MP3, WAV, FLAC, AAC and OGG without uploading anything. Drop a file, pick the output format and quality, download — decoding and encoding happen in your browser.
The list of formats is checked against your browser when the page loads, so you only ever see outputs your browser can actually produce. MP3 encoding falls back to a built-in encoder when your browser lacks one.
Why Use This Audio Converter Tool?
- Five output formats — MP3, WAV, FLAC, AAC (.m4a) and OGG (Opus), feature-detected per browser
- Bitrate control — 320, 256, 192, 128 or 96 kbps for the lossy formats
- 100% private — audio is decoded and re-encoded in your browser
- Free, no signup, no daily limits
- No upload wait — work starts the moment you press Convert
How to Convert Audio — 3 Steps
- Drop your audio file into the box above, or tap the box to pick it from your device.
- Pick the output format from the list, and a bitrate if the format is lossy.
- Press the blue Convert button and download the result.
One Converter for the Formats That Matter
Audio conversion is a small set of recurring jobs: a voice memo that needs to be MP3, a WAV recording that must shrink, a FLAC track for the car stereo, an Opus clip from Discord that nothing else will play. This tool covers them with one interface — drop the file, choose the target, download. The browser does the decoding and encoding locally, which means there is no upload for a 50 MB FLAC and no queue behind other people's jobs.
Format choice, plainly: MP3 is the universal pick — every device, app and car head unit plays it. WAV is uncompressed and huge but lossless, which editors, samplers and processing pipelines want as input. FLAC is lossless compression — album-quality at half the WAV size. AAC in an .m4a container is what iPhones, iTunes-era workflows and many streaming services use natively. OGG (Opus) packs the best quality per byte and is what modern voice apps record, but older players ignore it.
Bitrate decides size versus fidelity for the lossy formats: 320 kbps is effectively transparent, 192 kbps is the sensible everyday choice, 128 kbps suits voice and podcasts, and 96 kbps is for when the file size matters more than the details. Lossless formats ignore the bitrate control entirely.
An honest note on browser support: the encoding side is checked when the page loads, and the tool only offers formats your browser can produce — with a built-in LAME encoder covering MP3 everywhere. Decoding is similarly honest: if your browser cannot read a container (OGG on some Safari versions, for example), the tool tells you rather than producing a broken file.
Frequently Asked Questions
MP3, WAV, FLAC, AAC (.m4a) and OGG (Opus). The exact list is checked against your browser when the page loads — you only see formats that will genuinely work.
No. Decoding and encoding run in your browser's memory. You can disconnect from the internet after the page loads and it still works.
192 kbps for everyday listening, 320 kbps when quality matters, 128 kbps for voice and podcasts, 96 kbps when size beats everything.
Your browser cannot encode it. Support varies between browsers; the tool only offers formats that will genuinely produce a working file.
This tool accepts audio files. For video, use the dedicated tools in the Video Tools hub, then convert the result here if needed.
Converting between lossy formats (MP3 to AAC) adds a small amount of generational loss. Going to WAV or FLAC adds none. Choose sensible bitrates and it will not be audible.
Yes, with the browser checking formats as usual. The download lands in your Files app or Downloads folder.
