How to Compress 4K Video Online Free for Sharing

Compressing 4K video for sharing is increasingly necessary as smartphone cameras default to 4K recording, producing enormous files that are impractical to send or upload directly. WikiPlus Video Compressor at wikiplus.co reduces 4K video to 1080p or 720p and recompresses at lower bitrates entirely in the browser—no upload, no server processing, no account. A typical 4K video at 100 MB per minute can be reduced to under 20 MB per minute in 1080p with minimal visible quality loss at normal viewing sizes.
