Frequently asked questions

How do I convert WebM to AAC?

Click “Choose Files” and select your WebM file (or drag it onto the page). AAC is already selected as the output, so just click Convert and download your AAC file when it’s ready.

Will the audio quality change?

The audio is saved at high quality (192 kbps by default). If the video’s soundtrack is already in a compatible format, it is copied without any quality loss.

Is it safe to convert WebM files here?

Your files stay on your device. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.

Is the WebM to AAC converter free?

Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.

Can I convert several WebM files at once?

Yes. Add as many WebM files as you like and convert them in one go, then download them one by one or together as a ZIP file.
