This tool converts MP4 to M2TS 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 MP4 to M2TS Online
With this convertor, you can easily convert multiple MP4 files to M2TS 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 M2TS files.
Additional Settings:
Video Size: Set the width and height for the output M2TS 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 M2TS files will be saved. Each MP4 file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all MP4 files are converted, click
Save All to instantly save all M2TS files to your selected folder.
About MP4 files
MP4 (MPEG-4 Part 14) is a widely used digital video container format that stores video, audio, subtitles, and metadata in a single file. It supports efficient compression (e.g., H.264/AVC or H.265/HEVC) while maintaining good quality, making it ideal for streaming, downloads, and sharing. MP4 is highly compatible with most devices, media players, and online platforms (e.g., YouTube, smartphones) due to its standardized structure. Though less flexible than MKV, it balances quality, file size, and universal playback support. We can also convert MP4 files to animated images (e.g., GIF , WEBP , APNG)
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.
