Your MP4 file stays on your computer and is never uploaded to our servers. We do the AAC conversion in your browser.
Existing online MP4 to AAC converters require that you upload your MP4 file to their servers. They then do the AAC file conversion on their servers. So your data essentially leaves your computer and now resides on a server that someone else runs.
If you have confidential MP4 recordings, this might give you a pause.
We wanted to do better. We wanted to build an audio/video conversion tool that can be used securely, without the data ever leaving your computer. Many modern-day browsers are advanced enough that the file format conversion can be done right within your browser, without having to upload files anywhere. And this is exactly what we do.
When you select a file, we read the MP4 contents into your browser, convert it into AAC and save it back via your browser to your computer. Though the program that converts your MP4 files comes from our servers, the converter program still runs directly in your browser.
We also hate intrusive ads that show up on many of the existing online audio converter sites. So we wanted to build an audio / video converter that’s not only secure, but also has a good & intuitive user experience.
Yes! This MP4 to AAC converter is 100% free to use for both personal and commercial use.
Our primary product is actually our AI-based Transcription Software that helps you convert recorded speech in audio and video files into text. We initially built this audio / video format converter tool for our transcription software users, but then figured that it’s useful enough to make available to everyone.
By giving away this MP4 to AAC converter for free, we hope that you will consider using our transcription software in the future, when you do have a need, or share this out with friends who might want to do transcriptions.
It usually takes about 1/3rd the duration of your MP4 file to convert it into a different format.
