Why use SnipSound's converter

OGG, FLAC, AAC and M4A as output formats are coming soon. Today's converter outputs MP3 and WAV from any input.

Free Online Audio Converter

SnipSound's audio converter turns any audio file into MP3 or WAV directly in your browser. Drop in an MP3, WAV, OGG, FLAC, AAC, or M4A file, choose your output format and quality (MP3 bitrate from 128 to 320 kbps, or lossless WAV), and download the converted file. No upload, no signup, no watermark.

How It Works

The converter decodes your source file using your browser's Web Audio API, re-encodes it into the target format on the fly, and offers the result as a download. MP3 encoding uses a JavaScript port of LAME; WAV output is direct PCM. The whole conversion happens locally on your device — your audio never leaves your computer.

Why Convert Audio Formats?

Common reasons: making a FLAC archive playable on phones that only handle MP3 or AAC, converting voice memos from M4A to MP3 for upload to platforms that reject M4A, shrinking a WAV recording to a smaller MP3 for emailing, or producing a lossless WAV master from a compressed source for editing. Browser-side conversion means no file-size limits from upload services.

Frequently Asked Questions

How do I convert audio files online?
Drop your audio file onto the page, pick the output format (MP3 or WAV) and quality, then click Convert. The converted file downloads to your device.
What input formats are supported?
Any format your browser can decode — MP3, WAV, OGG, FLAC, AAC, M4A and more.
Is my file uploaded?
No. All processing happens in your browser via the Web Audio API. See our privacy policy.
What's the difference between WAV and MP3?
WAV is lossless — every sample is stored exactly, so quality is perfect but file size is large (~10 MB/minute). MP3 is lossy — it discards information the ear is less sensitive to, so files are 10x smaller at 192–320 kbps with very little audible difference.
When will OGG / FLAC / AAC output be supported?
Soon. Browser-native MP3 and WAV encoding is supported today; OGG, FLAC, AAC and M4A output will arrive via in-browser FFmpeg.
