About This Tool

Our M3U8 to MP4 converter is a powerful, browser-based tool that transforms HLS (HTTP Live Streaming) video streams into universally compatible MP4 files. Unlike traditional converters, this tool operates entirely within your web browser using WebAssembly technology, ensuring your videos are processed locally without ever being uploaded to external servers. This approach guarantees complete privacy and eliminates bandwidth limitations, making it perfect for users who value both convenience and security.

What is M3U8?

M3U8 is a UTF-8 encoded playlist file format used primarily for HLS (HTTP Live Streaming) video delivery. Developed by Apple, this format has become the industry standard for adaptive streaming across the internet. An M3U8 file contains references to media segments (typically .ts or .m4s files) along with metadata about the stream, including resolution variants, audio tracks, and subtitles. While this format excels at delivering smooth streaming experiences, the segmented nature makes it challenging to save videos for offline viewing—which is exactly the problem our converter solves.

How to Convert M3U8 to MP4

  1. 1Copy the M3U8 URL from your video source (right-click on the video or check your browser's developer tools under the Network tab)
  2. 2Paste the URL into the input field above or upload an M3U8 file directly
  3. 3Click "Convert to MP4" and wait for the process to complete
  4. 4Once finished, click the download button to save your MP4 file

Frequently Asked Questions

Is this converter free to use?
Yes, completely free with no hidden costs, no registration required, and no watermarks on your converted videos.
Are my videos uploaded to a server?
No. All processing happens directly in your browser using WebAssembly. Your video data never leaves your device, ensuring complete privacy.
What types of M3U8 streams are supported?
Our tool supports both standard TS (Transport Stream) segments and modern fMP4/CMAF formats, including streams with separate audio tracks.
Why is the conversion taking a long time?
Conversion speed depends on the video length, your internet connection (for downloading segments), and your device's processing power. Longer videos naturally take more time.
Can I convert DRM-protected streams?
No. Streams protected by DRM (Digital Rights Management) such as Widevine or FairPlay cannot be converted. This tool only works with unencrypted HLS streams.
