Best Practices for Using an Online Video Compressor to Reduce File Size

A smaller file does not have to lose visual impact. With a few simple adjustments, you can compress your videos whilst keeping them clean, smooth and ready to share. HeyGen recommend trimming extra footage before exporting to lower the overall file size and choosing 1080p or 720p for the best balance of clarity and compression.

If you’re using avatars, graphics or voiceovers, keep your scenes simple so the compressor can work efficiently. Always preview your video before downloading to make sure everything looks right. These practices help you produce videos that load quickly and remain easy to share across any device
