This tool converts M4V to CAF 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 M4V to CAF Online
With this convertor, you can easily convert multiple M4V files to CAF 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 CAF files.
Additional Settings:
Video Size: Set the width and height for the output CAF 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 CAF files will be saved. Each M4V file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all M4V files are converted, click
Save All to instantly save all CAF files to your selected folder.
About M4V files
M4V is a digital video format developed by Apple, based on the MPEG-4 standard. It is commonly used for storing movies and TV shows, especially those purchased or rented from iTunes. Like MP4, M4V supports high-quality video and audio compression, but it may include DRM (Digital Rights Management) protection to restrict unauthorized copying. M4V files can be played on Apple devices like iPhone, iPad, and Mac, as well as some other players that support the format. Its compatibility depends on whether DRM is applied.
About CAF files
The CAF (Core Audio Format) is an audio file format developed by Apple for professional audio applications. It supports high-quality audio with flexible compression options and can store multiple tracks, metadata, and effects. CAF is widely used in Apple's audio production tools like Logic Pro and GarageBand due to its reliability and large file size support. While not as common as MP3 or WAV, it is valued for advanced audio editing and recording needs.
