A phone video easily weighs 200–500 megabytes for a couple of minutes of footage. Email will not take that: most mail services cap attachments at about 25 MB. Messengers formally allow more — Telegram accepts files up to 2 GB — but a huge file takes ages to upload, eats the recipient's mobile data, and WhatsApp compresses videos on its own anyway, with noticeably worse quality than if you had shrunk the clip yourself beforehand.
The fastest way: compress in the browser
No programs to install, no codec settings to learn. Open the video compressor, drag your file in and pick a compression level:
- Light — nearly lossless, the file gets roughly a third smaller.
- Balanced — the sweet spot for sharing: several times smaller with the picture still looking good.
- Strong and maximum — when size is what matters: long clips and slow connections.
You can also cap the resolution — on a phone screen 720p is indistinguishable from the original while weighing far less — and drop the audio track if you do not need it.
Your file is never uploaded
The key difference from upload-based converters: everything runs right in your browser. The video never leaves your device — no queues, no "100 MB free" limits, no risk of a personal clip staying on someone's server. That is also why multi-gigabyte files are perfectly fine here.
Frequently asked questions
How much smaller will the file get? It depends on the source. Phone footage is usually recorded with a large quality margin, so the balanced preset typically shrinks it 2–5x with no visible difference on screen.
Why do WhatsApp videos look blurry? The messenger compresses video itself, aggressively and with no settings. If you shrink the clip to a reasonable size first, WhatsApp barely recompresses it — and the quality stays under your control.
What if I only need to cut a piece out? Then you may not need compression at all: trim the video — without re-encoding it takes seconds and loses no quality whatsoever.
