WhatsApp caps media sharing (16 MB for statuses, and larger chat videos get recompressed hard by the app itself). Send a smaller, cleaner file and you control what the recipient sees instead of letting WhatsApp's aggressive recompression decide.
This page opens the video compressor on the 480p / 1 Mbps preset, which puts roughly a minute of video around 8 MB. The math is simple: size is bitrate times duration, and the tool shows the estimate before you commit to the real-time re-encode.

This is Compress Video preconfigured for this task — open the full tool for every option.
Select a video; its resolution, duration, and size are shown.
Choose MP4 (H.264/AAC) or WebM (VP9/VP8), then pick a preset or custom resolution and bitrate.
Export — the video replays through a scaled local canvas and re-encodes at the chosen bitrate and supported browser codec.
Before/after sizes are reported from the actual output bytes.
The selected MP4 or WebM container signature is checked, then the compressed output is re-decoded locally to confirm it plays. Its true byte size and duration are measured before download.
At the 480p preset with audio, roughly 100 seconds. Halve the bitrate in custom mode and you get about twice that, with visibly softer quality.
WhatsApp recompresses whatever you send to save bandwidth. Feeding it an already-small file at the right resolution gives its encoder less to butcher.
Technical guidance for choosing settings and reviewing the result.
Video compression is a set of measurable tradeoffs, not a mystery slider. Here is what actually changes file size, how to estimate the result, and which setting to adjust first.

An .mp4 or .webm extension names a container, not a quality level. The streams inside—and the browser or device that must decode them—are what determine compatibility and size.
