How it works

Choose your file

Pick a supported file from your device or drop it into the tool.

Set the result

Choose the output, quality, or size options that matter for this job.

Convert and download

Your browser processes the file locally and prepares a fresh download.

Before you start

The file picker accepts: .3g2, .3gp, .aac, .aiff, .avi, .flac, .flv, .m4a, .m4v, .mkv, .mov, .mp3, .mp4, .mpeg, .mpg, .ogg, .ogv, .opus, .wav, .webm, .wma, .wmv, audio/*, video/*. The contents and encoding of the file must also be supported; an extension alone does not guarantee compatibility.

The download uses the .m4a extension. Keep the source until you have checked the result.

What to expect

Choose the output for the player or editor you will use next. Converting a compressed recording cannot restore detail already lost in the source. Listen to a short section of the download before using the whole file.

Limits to keep in mind

Large media files may exceed browser memory or take substantially longer than native conversion.

Frequently asked questions

Is the file uploaded?＋

File contents are processed on your device. The browser downloads the tools it needs, but does not upload your file to LocalConvert for conversion.

What if processing does not finish?＋

Read the error shown by the tool. An unsupported format needs a different input; running out of memory may require a smaller file or a more capable device. Keep the tab open while the job runs.
