AVI to F4V Converter

Convert AVI files to F4V. Free, without uploading.

This tool converts AVI files to F4V. AVI is Windows’ classic video container. Older players and some devices still want it; files are larger than with modern formats.

Flash MP4 video. The video is re-encoded. You choose the quality and resolution, and can trim it with a start and end time.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the AVI video, drag it in, or paste its link.
2. Choose the quality and resolution; optionally enter trim times.
3. Press "Convert" and download the F4V file.

No fixed limit; your device’s memory decides. Computers usually handle files up to 1–2 GB.
