ASF to WMV Converter

Convert ASF files to WMV. Free, without uploading.

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

WMV is Microsoft’s Windows Media video format, used by older Windows software and older PowerPoint versions. The video is re-encoded with WMV2 video and WMA 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 WMV file.

Frequently asked questions

How long does ASF to WMV 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 WMV inside your browser.
