About this audio converter

This tool converts audio files between common formats — MP3, WAV, OGG, FLAC and M4A — directly inside your browser. There's no upload step and no server involved, so your files stay on your device the entire time, whether you're converting a single voice memo or prepping tracks for a project.

Choose your output format

Pick the format you need and adjust bitrate, sample rate and channel count to match your use case — higher bitrates for music, lower ones for speech or smaller file sizes.

Check the details

Before and after converting, see the format, duration, sample rate, channels, bitrate and file size, so you can confirm the conversion did what you expected.

Preview and download

Play the converted file right on the page before downloading it, so you can catch any issues without leaving the tool.

Tips for choosing the right settings

  • Use 192–320 kbps for music you want to sound close to the original.
  • 96–128 kbps is usually plenty for spoken word, podcasts or voice memos.
  • Switch to mono if the source is a single voice — it halves the file size with no real quality loss for speech.
  • Keep the original sample rate unless a specific device or app requires a different one.
  • WAV and FLAC are lossless and larger; MP3, OGG and M4A are compressed and much smaller.

Frequently asked questions

Is this audio converter free to use?

Yes. There's no limit on how many files you can convert, no watermark, and no account required.

Are my audio files uploaded to a server?

No. The conversion runs entirely in your browser. Your file never leaves your device.

What's the maximum file size I can convert?

Files up to 25 MB are supported, since everything is processed locally in your browser's memory.

Which format should I choose?

MP3 is the safest choice for compatibility across devices and apps. Use WAV or FLAC if you need lossless quality, and OGG or M4A if a specific platform requires them.

Will converting to a lossy format reduce quality?

Yes, formats like MP3, OGG and M4A compress audio by discarding some data. Converting from one lossy format to another, or lowering the bitrate, can reduce quality further, so start from the highest-quality source you have.
