4 methods for compressing .wmv files

Option 1. How to Compress WMV Files without Losing Quality? (Use HEVC Codec)

HEVC/H265 is an advanced video codec that can encode video into small size file while not compromising the original quality. Here is how to convert WMV to HEVC to reduce WMV file size:

Click the right side format image and go to the “Video” section. Select “H265 for MKV” or “H265 for MP4” as the output format.

Tips. The latest AV1 encoding format has an even higher compression ratio. You can choose the MP4 format and then go to "Parameter settings" to change the encoder to AV1 to have a try.

Option 2. Compress a WMV File by Changing Resolution

Hit the "Parameter settings" button to open the settings window. Then open the drop-down list of Resolution to downscale resolution of the WMV video. By adjusting resolution, you can also compress 4K videos to 1080P, 720P, 480P at ease. If you don't need to alter other parameters, you can slide the resolution button below the Parameter settings button to adjust the video resolution in a click.

Option 3. Lower Bitrate to Compress a WMV File

In the Parameter settings, find Bit rate and drop the value to decrease WMV file size.

Option 4. Decrease Frame Rate to Compress WMV

Still in the Parameter settings, open the Frame Rate drop-down list to choose a lower value. Generally speaking, lower frame rate leads to smaller file size and less smoothness.
