Sending videos on WhatsApp
WhatsApp can send large files as documents, but those do not play inline for the person receiving them. Sending as regular video is nicer, and smaller videos send faster on mobile data. Pre-compressing to 720p means WhatsApp has less to squeeze, so the video arrives sharper.
Good to know
Compression uses H.264 (x264, "veryfast" preset) with either a quality target (CRF) or a calculated bitrate for target sizes. Audio is re-encoded to AAC. The file is never uploaded, so even private videos can be compressed safely.

Frequently asked questions
How long a video fits in 16 MB?
At 720p, around 1–2 minutes looks good. For longer videos, raise the target or lower the resolution to 480p.
Do I have to pay or sign up to use the Compress Video for WhatsApp?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Do you keep a copy of my files?
We never receive them. All processing happens on your device, so there is nothing for us to store or delete.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
