First use downloads the video engine once (about 31 MB). After that it’s cached and starts instantly.
How much smaller will it be?
Phone videos often shrink by 60–90% at Medium compression with Max 720p, with little visible difference on a phone screen. Reducing resolution saves the most space. Compression happens on your device, so a 1-minute 1080p clip can take a minute or two on an average laptop. Keep the tab open until it finishes.
How to use the Compress Video

Frequently asked questions
Is my video uploaded to a server?
No. The conversion runs inside your browser using a WebAssembly version of FFmpeg, the same engine professional video tools use. Your file never leaves your device.
Why does it take longer than desktop software?
It runs on a single processor core inside your browser, so re-encoding is slower than native apps. Conversions that can copy the original streams (no re-encoding) take only seconds.
What size works for WhatsApp?
WhatsApp sends videos up to about 16 MB without heavy recompression of its own. Medium compression at 480p usually gets a 1–2 minute clip under that.
