Video size reducer
Make any video smaller by choosing the size you want — the reducer works out the rest. Your file is shrunk on your own device and never uploaded anywhere.

Bigger files take longer — your CPU does the work, privately.
Reduce by target, not by guesswork
Video file size comes down to two things: the bitrate (how much data each second of video uses) and the resolution. A reducer lowers the bitrate — and downscales the resolution only when needed — to hit the size you ask for. Most phone and screen recordings carry far more bitrate than they need, so there’s usually plenty to trim before quality suffers.
Instead of guessing export settings, type the target size you want (or pick a platform preset) and the tool calculates the bitrate to land just under it, based on how long your clip runs. Shorter clips keep more quality at any given size.
How small should you go?
Don’t over-shrink. Pick the largest size your destination actually allows — 25 MB for an email, 16 MB for WhatsApp, 10 MB for Discord — so the encoder keeps as much detail as possible. Going smaller than you need just throws quality away.
If a clip won’t reach watchable quality at your target, trim it to the part that matters first. The same data budget spread over fewer seconds always looks sharper than stretching it across a long video.
Frequently asked questions
How do I reduce the file size of a video?
Drop the video in, choose a target size (or a platform preset), and download the smaller file. The reducer lowers the bitrate — and the resolution if needed — to hit your target, all in your browser with nothing uploaded.
Can I reduce video size without losing quality?
You can reduce it with very little visible loss by keeping the original resolution and trimming only the bitrate you don’t need. Some loss is unavoidable with any compression, so pick the largest target your destination allows for the best result.
What’s the difference between a size reducer and a compressor?
They’re the same thing here — both lower the bitrate (and optionally the resolution) to make the file smaller. “Reducer” just names the goal: hitting a specific, smaller file size.
Is my video uploaded to reduce it?
No. The whole process runs in your browser on your own device. Your video is never uploaded to a server — you can even go offline once the page has loaded.
