About RMVB files
RMVB (RealMedia Variable Bitrate) is a video file format developed by RealNetworks as an extension of the RM format. It uses variable bitrate compression to improve video quality while keeping file sizes relatively small. RMVB was widely used for online video distribution in the past. Today, it is considered a legacy format with limited support on modern media players and platforms.
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.

Batch Convert RMVB to CAF Online

With this convertor, you can easily convert multiple RMVB 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:

  • Output Dimension: 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 RMVB file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.

    Save All: Once all RMVB files are converted, click Save All to instantly save all CAF files to your selected folder.
