Batch Convert WEBM to F4V Online

With this convertor, you can easily convert multiple WEBM files to F4V 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 F4V files.

Additional Settings:

  • Video Size: Set the width and height for the output F4V 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 F4V files will be saved. Each WEBM file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.

    Save All: Once all WEBM files are converted, click Save All to instantly save all F4V files to your selected folder.

    About WEBM files

    About F4V files

    F4V is a video format based on the H.264/MPEG-4 AVC standard, developed by Adobe for Flash-based video streaming. It is commonly used for online videos, especially those embedded in websites via Flash Player. F4V supports high-quality video and audio compression, making it efficient for streaming. However, with the decline of Flash, F4V has become less popular, and modern browsers now favor MP4 or HTML5 formats instead. It remains compatible with some media players and Flash-based applications.
