A 90 MB phone clip won't send in a messenger or fit email. Compression re-encodes the video into an efficient codec: resolution caps at 1280 px, bitrate is chosen sensibly — weight drops 2–5× while staying watchable on screen. It's the server's heaviest operation, hence one per day. Often it pays to trim the excess first — a short fragment compresses faster and weighs less. All tools — in one section.

Where video weight comes from

Weight is resolution × bitrate × duration. Phones record 4K with a huge bitrate margin “just in case” — chat viewing needs a quarter of it. Compression trims the margin: 1280 px and an economical bitrate are indistinguishable on a phone.

Compress or trim: which to pick

Need a fragment — trim first: a minute-long clip after trimming may need no compression at all. Need the whole clip — compress. The trim → compress combo yields minimal weight for the same content.

The limits of sensible compression

Twice-compressed video visibly smears: artifacts accumulate. Keep the original; use the compressed copy for sending. And don't expect miracles from an already-compressed file — if there's nothing to squeeze, we honestly return the original.
