Completely Private Audio Conversion

Most online converters upload your files to their servers. Not us. Our converter processes everything in your browser on your device. Your files cannot be accessed by us or anyone else.

How Private Conversion Works

When you select a file, it stays on your device. The conversion runs locally in your browser and the converted file is created there too. At no point does any data leave your computer or phone.

Why Privacy Matters for Audio

Audio files can contain sensitive content - personal conversations, business discussions, creative work, private recordings. When you upload to traditional converters, you're trusting unknown servers with this content.

Who Needs Private Conversion?

Professionals handling confidential client recordings
Anyone with personal voice recordings or memos
Businesses converting sensitive meeting audio
Creators protecting unreleased work

We don't collect data because we can't - our architecture makes it impossible. No file storage, no user tracking, no data collection. This is privacy by design, not privacy by policy.

Format Guide & Compatibility

Use this quick guide to choose the right output settings for MP3 conversion.

Use MP3 when you need maximum device and app compatibility.
If quality is critical, compare MP3 output with lossless options like WAV or FLAC.
MP3 usually delivers smaller file size for sharing and storage.
Popular workflows for this tool include WAV -> MP3, M4A -> MP3, MP3 -> WAV.
All conversion runs locally in your browser, so your source files stay on your device.

WAV vs MP3 vs M4A

Format	File Size	Quality	Best For
WAV	Large	Lossless	Editing and archiving raw quality
MP3	Small	Good	Everyday listening, universal sharing
M4A	Small to medium	Very good	Mobile playback and streaming

Troubleshooting

File is not supported

Re-export your source file in a common format and try again. Corrupted files may fail to decode.

Output has no audio

Your source may not contain an audio track, or it may use an uncommon codec. Try another source file to confirm.

Conversion is slow

Close heavy browser tabs and background apps. Local conversion speed depends on your device CPU and file size.

Large files fail

Split very large files into smaller parts or use a shorter clip first, then convert full media on a more powerful device.

Download did not start

Allow downloads for this site in browser settings and retry. Some blockers can prevent automatic file downloads.

Frequently Asked Questions

How can I verify my files aren't uploaded?

Open your browser's developer tools and watch the Network tab during conversion. You'll see zero file transfers. Alternatively, disconnect from the internet - the converter works offline.

What about the site's privacy policy?

Our policy confirms no data collection, but the real assurance is the technology itself. Since processing is local, there's nothing to collect even if we wanted to. This is privacy through architecture.

Is this more private than desktop software?

Equally private - both process locally. Desktop software could theoretically phone home, while our browser-based approach is sandboxed. Both keep files on your device during conversion.

What happens to files after conversion?

Nothing - they exist only in your browser's memory during conversion, then download to your device. Close the tab and everything is gone. We have no server-side storage.

Can my ISP see my files?

No. The initial page load is the only network activity. Your files never travel over the network. Your ISP sees you visited the site, not what files you converted.
