How much smaller?
Phone cameras record at a high bitrate so every frame looks sharp, which makes files much bigger than they need to be for sharing. Re-encoding with modern settings removes most of that extra weight while the picture still looks the same on a phone screen.

Why use this video compressor
Private by design
Compression runs inside your browser. Your video is never uploaded to a server, so nobody else can see it.
Free, with no watermark
There is no account, no daily limit and no logo stamped on your video. What you download is yours.
Works on any device
Use it on Windows, Mac, Chromebook, iPhone or Android. Nothing to install — a modern browser is all you need.
Plays everywhere
You get an H.264 MP4 with AAC audio, optimized for fast start, so it plays on phones, TVs and every social app.
Which settings should I choose?
Light keeps the most detail and gives a moderate size reduction. Use it for videos you plan to edit again or watch on a big screen. Balanced is the default and the best choice for sharing: the quality loss is hard to notice on a phone, and the file usually shrinks a lot. Strong squeezes the file as much as possible and works well for screen recordings, long clips and email attachments.
Lowering the maximum resolution is the other big lever. A 4K or 1080p video scaled down to 720p is often a fraction of the size and still looks sharp in a chat app. The tool never upscales: if your video is already smaller than the limit you pick, its resolution stays the same, and vertical videos keep their shape.
Compressing for WhatsApp, email and Discord
WhatsApp shrinks videos again when you send them as a video, so a file that already looks good at a smaller size arrives in better shape. Before you share, compress it on Balanced with the maximum resolution set to 720p. If quality matters more than speed, attach the video as a document instead: WhatsApp then sends the original file, up to 2 GB.
Gmail accepts attachments up to 25 MB; anything larger is sent as a Google Drive link instead. Choose Under 25 MB and the tool fits the video to that size, lowering the resolution only if it has to. If the video is too long to look good at that size, the tool tells you, and sending a link is the better choice.
Discord and other chat apps also limit the size of each file, and the limit depends on your plan. Choose Under 10 MB to stay within even the strictest limits. Trimming the video to the part you need saves the most space, because the file grows with the length of the clip; most phones can trim a video right in the gallery.
Good to know
Because everything happens on your device, the speed depends on your computer or phone. A short clip takes seconds; a long 4K video can take several minutes, so keep the tab open until it finishes. The first time you compress, your browser downloads the video engine once, which takes a moment on a slow connection.
