How do I make a video small enough for WhatsApp?

Choose WhatsApp and press Compress video. The quality is worked out from the length so the file comes out under 16 MB. Long videos can look blocky at that size; trim them or pick a lower resolution.

How long does it take?

It depends on your device and the video’s length and resolution; it often takes longer than the video itself, and longer still on phones or at 1080p. You see the progress and time left, and can cancel at any point.

What is the largest video it can handle?

Up to 2 GB, the browser memory limit. Files up to 500 MB work best, especially on phones. For a longer video, trim to the part you need.

Can it convert MOV or MKV to MP4?

Yes. The result is always an MP4 with H.264 video and AAC sound, which plays on every phone and browser and is accepted by WhatsApp and YouTube.
