How to Compress Video Online Without Losing Quality

Why compress videos?

Heavy videos slow page load, burn visitor data and hurt ad performance. Compressing the file — while keeping the correct aspect ratio — reduces size without distorting the image.

How to use our tool

1. Open the [Video Compressor](/en/video-compressor)
2. Enter the current width and height of your video
3. Set the desired final width
4. Use the automatically calculated height on Compresss.com

Practical tips

• Remove audio if the video is visual-only (banners, silent stories)
• For the web, widths between 720px and 1280px are usually enough
• Always keep the original aspect ratio to avoid distortion

When is it worth it?

Compress whenever you publish videos on landing pages, ads or product pages. Smaller files improve UX and Core Web Vitals.
