A LITTLE KNOW-HOW

Match a project sample rate

Choose 44.1 kHz for many music workflows or 48 kHz for video workflows. Resampling changes the number of samples per second; it does not add detail that the original recording lacks.

Your output, your settings

WAV here contains uncompressed 16-bit PCM audio. It is useful for editing and predictable playback, but occupies much more space than a lossy format. Converting a compressed source to WAV does not restore missing detail.

GOOD QUESTIONS

A few things
you might wonder.

Still curious? Get in touch.

Is it really free?

Yes. All tools are free to use, with no registration, subscriptions or payments. Upload and processing limits apply to keep the service usable.

Where are my files processed?

Files are uploaded to the server for processing with FFmpeg. They are not processed exclusively in your browser.

When are files deleted?

Downloads expire after 60 minutes from upload. Automatic cleanup removes original and converted files after expiry; the cleanup schedule runs every minute when configured.

Will converting improve the sound quality?

Changing a format or increasing a bitrate cannot restore information lost in the original file. Keep your original when editing or archiving.
