This tool converts M2TS to AAC completely free and without any functional limitations. Since it is based on the browser API, the processing speed is the fastest because all files are processed locally on your device and are not uploaded to our server.
Batch Convert M2TS to AAC Online
With this convertor, you can easily convert multiple M2TS files to AAC format directly in your browser — completely free. You can also customize the video resolution (width and height) during the conversion.
To access advanced settings, click the Options button in the top right corner. There, you can set the output size for your AAC files.
Additional Settings:
Video Size: Set the width and height for the output AAC file.
Encoding Speed:Controls how fast the video is encoded. Faster speeds may result in larger file sizes.
Video Bitrate:Set between 1–10,000 Kbps to control the video quality and file size.
Frame Rate:Defines the video’s FPS (frames per second). Higher frame rates produce larger files.
Audio Bitrate:Recommended range is 16–320 Kbps.
Cut Video: Trim the video using a start and end time in HH:MM:SS format.
For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the video or animation.
Before converting, you can choose a folder on your device where the converted AAC files will be saved. Each M2TS file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all M2TS files are converted, click
Save All to instantly save all AAC files to your selected folder.
About M2TS files
M2TS is a video container format based on the MPEG-2 Transport Stream (TS) standard, primarily used for high-definition video storage on Blu-ray discs and AVCHD camcorders. It preserves high-quality audio/video streams (like H.264/AVC and LPCM/DTS) with minimal compression loss. The format supports multiple audio tracks, subtitles, and chapter markers, making it ideal for professional video editing and home theater systems. While large in file size, M2TS ensures broadcast-grade quality for Blu-ray playback and digital broadcasting.
About AAC files
AAC (Advanced Audio Coding) is a highly efficient audio compression format developed by Fraunhofer IIS, AT&T, Dolby, and others. It delivers better sound quality than MP3 at similar bitrates, making it ideal for music streaming, podcasts, and mobile devices. AAC is the default audio format for Apple products (iTunes, iPods, iPhones) and is widely supported across platforms. Its lossy compression reduces file sizes significantly while maintaining excellent audio fidelity, though it's not as universally compatible as MP3.
