Shrink a clip so WhatsApp sends it fast and skips heavy recompression —
free, no watermark, and 100% in your browser. Your video is never uploaded.
How to compress a video for WhatsApp
Drop your clip above — it's processed on your device, not uploaded.
The 16 MB target is preselected. Trim to the exact moment you want to share.
Click Compress video, download, and send it on WhatsApp.
Why compress before sending?
WhatsApp aggressively recompresses big videos, which can make them look worse and take longer to send.
Getting under ~16 MB first means it uploads quickly on mobile data and keeps more of its original quality.
Trimming to the key moment lets SumoSquash spend the bitrate where it matters.
What size should a WhatsApp video be?
Under ~16 MB keeps quality and sends fast; smaller is even quicker on mobile data.
Is the video uploaded to SumoSquash?
No — it's compressed in your browser; you share it via WhatsApp yourself.
How do I keep it looking good?
Trim to the part you actually want to send — shorter clips look better at the same size.
