Tips: How Can Video File Size Be Compressed on Windows

1. Convert/compress video to other formats which has higher compression: MP4 is top recommended as it is accepted by most media players, devices and websites, and has a fame for good compression with relatively smaller size. You can convert large video files to a more efficient codec format, such as H.264 to HEVC etc. for smaller size yet same high quality. If your devices support H.265 codec, you can further compress the video to 50% smaller by re-encoding H.264 codec to HEVC without quality loss.

2. Reduce the bit rate: This is a lossy video compression. You could compress the video by reducing its bit rate to get a smaller size, but you will get inferior video quality. Lower bit rate, smaller size, lower quality.

3. Lower the video resolution: Also a lossy compression. You can downscale video resolution like 4K to 1080p, HD to 720p/480p etc. with this free video shrinker for Windows 10 to perfectly fit for iPhone iPad, etc.
