ASF to AVI Converter

Convert ASF files to AVI. Free, without uploading.

This tool converts ASF files to AVI. Advanced Systems Format.

AVI is Windows’ classic video container. Older players and some devices still want it; files are larger than with modern formats. The video is re-encoded with MPEG-4 video and MP3 audio. 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 ASF video, drag it in, or paste its link.
2. Choose the quality and resolution; optionally enter trim times.
3. Press "Convert" and download the AVI file.

Frequently asked questions

How long does ASF to AVI take?

It runs on your device’s processor. On a computer a one-minute 1080p video usually takes a minute or two; lowering the resolution speeds it up.

Is there a file size limit?

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

Is my file uploaded?

No. Your ASF file is converted to AVI inside your browser.
