This tool converts AVI to F4V 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 AVI to F4V Online
With this convertor, you can easily convert multiple AVI 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 AVI file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all AVI files are converted, click
Save All to instantly save all F4V files to your selected folder.
About AVI files
AVI (Audio Video Interleave) is a classic multimedia container format developed by Microsoft in 1992. It stores both video and audio data in a single file while maintaining synchronization between them. Though widely compatible with most media players and systems, AVI files tend to be larger than modern formats (like MP4) due to limited compression efficiency and lack of advanced features. Still used for legacy systems, simple video editing, and some specialized applications where compatibility is prioritized over file size.
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.
