Audio Converter: Convert Audio to MP3, WAV, FLAC, M4A, OGG
Convert any audio your browser can read into MP3, WAV, FLAC, M4A or OGG, with real quality tiers for each format.
Every device and workflow has a format it insists on: a voice recorder hands you M4A, an editor wants WAV, a game engine wants OGG, an archive wants FLAC, and half the world still asks for MP3. This converter reads anything your browser can decode and re-encodes it in the format you pick, with the quality decisions exposed instead of hidden: CBR bitrates or VBR tiers for MP3, 16- or 24-bit for WAV, two AAC bitrates for M4A, two quality levels for OGG. Two optional conforming steps run before the encode: a mono downmix that averages the channels, and a resample to 44.1 or 48 kHz for targets that expect a standard rate. The result panel reports what actually happened: formats, sizes, rates, channels and the compression ratio, rather than just handing you a file.
How to Use It
- Upload your audio file and wait for the local preview to load.
- Adjust the settings: Pick the target format and its quality tier, and optionally downmix to mono or set a fixed 44.1 or 48 kHz sample rate before converting.
- Download the result: Download the processed file directly to your device.
Controls and Options
Each format exposes its own honest quality control: CBR bitrates from 128 to 320 kbps or V2/V0 VBR for MP3, 192 or 256 kbps AAC for M4A, q4 or q6 for OGG Vorbis, and 16- or 24-bit depth for WAV. Settings that do not apply to the chosen target are simply ignored, and the result panel reports the exact quality used together with sizes, rates, and the compression ratio.
Formats and Output
Reads common audio formats your browser can decode, including MP3, WAV, M4A, OGG, and FLAC. Exports MP3 (CBR or VBR), M4A (AAC), OGG (Vorbis), FLAC, and 16- or 24-bit WAV, named after your original file with the new extension.
Frequently Asked Questions
Which audio files can I convert?
Anything your browser can decode, which covers MP3, WAV, M4A, OGG, and FLAC in current browsers, and often more. The output side offers MP3 with CBR and VBR tiers, M4A with two AAC bitrates, OGG Vorbis at two quality levels, FLAC, and 16- or 24-bit WAV.
Which target format should I pick?
MP3 when the file has to play absolutely anywhere. M4A when you want the best sound per kilobit: AAC at 192 kbps typically matches or beats MP3 at 256. OGG when a game engine or open-source stack asks for it, or when the smallest musical file wins. FLAC when the audio should be stored compressed but with nothing discarded, and WAV when an editor or DAW wants plain uncompressed samples.
Does converting to FLAC or WAV improve the sound?
No, no format conversion can restore what a lossy encode already removed. FLAC and WAV store the decoded audio exactly as it came out of the decoder, so they are the right targets for editing or archiving without adding another lossy generation, but an MP3 converted to FLAC sounds exactly like the MP3, just bigger.
What is the difference between CBR and VBR for MP3?
CBR spends the same number of bits on every moment of the file, which makes size exactly predictable and keeps very old decoders happy. VBR lets the encoder spend more bits on busy passages and fewer on quiet ones, so at the V0 tier it usually sounds better than 256 kbps CBR while producing a smaller file. If you have no compatibility constraint, VBR is the better deal.
What do the channel and sample-rate options do?
They conform the audio before it is encoded. Downmix to mono averages the channels, for stereo, exactly half of left plus right, which halves the data in uncompressed formats and helps voice recordings. The sample-rate option resamples to 44.1 or 48 kHz for destinations that require a standard rate; leaving both on Keep passes the source layout and rate straight through.
Is my audio uploaded anywhere?
Supported audio content is not uploaded for processing. Decoding, conversion, and export run in your browser; site analytics and the assistant are separate.
