How to compress a video for WhatsApp without losing quality

WhatsApp's 16MB limit is the most common reason people need to compress video. The trick is to compress intelligently — enough to fit the limit, but not so much that it looks terrible on a phone screen.

Step-by-step

• Open our Video Compressor and drop in your clip
• Set CRF 28–30 — the sweet spot for messaging apps
• Output MP4 (WhatsApp plays H.264 universally)
• Compress, then check the new size below 16MB

Still too big? Trim the clip first with the Video Trimmer — a 2-minute clip compresses far better than a 10-minute one.

Why it works

WhatsApp re-compresses everything it receives anyway, so a slightly lower CRF on your side is invisible. What matters is hitting the size cap — and CRF 28–30 with a short clip does exactly that.

Quick tips

• Screen recordings compress very well — CRF 32 is fine
• Video shot in 4K: downscale to 1080p first (our compressor handles it)
• Send as a document if you need to bypass the 16MB cap — but quality is on the receiver
