Good to know about MP4 to MP3

Pick the MP3 quality under More settings: 192 kbps is great for music, and 128 kbps is fine for speech. This only works if the video actually has sound.

Questions

Is it safe to convert MP4 files here?

Yes. Your MP4 files are converted inside your own browser and are never uploaded to a server, so nobody else can see them. It works just as well for private or work documents.

Can I convert several MP4 files at once?

Yes. Add as many as you like, then press Convert. When they're done you can download them one by one, or all together as a single .zip.

Is it really free?

Yes, with no sign-up, watermarks or daily limits. The site is paid for by ads, which you can turn off in Cookie settings.

Download the text reader?

Reading text from images needs an extra recognition engine (about 10–15 MB) that is fetched from jsDelivr, a public file host. Like any website you visit, jsDelivr will see your IP address.

Your image is not sent anywhere. It is still processed on your device.
