How to Compress a Video on an Android Phone

Android has no universal built-in compressor either, but it gives you more ways round the problem than iOS does — and the settings that prevent it are in the camera app rather than buried in a system menu.

Record smaller

In your camera app's settings, video resolution is usually one or two taps away. 4K60 to 1080p30 is roughly a quarter of the size and indistinguishable on the phone itself. Many Samsung and Pixel cameras also offer an "efficient video codec" or HEVC option, which saves another 30% or so — with the same caveat as on iPhone, that HEVC occasionally annoys Windows PCs.

Sharing without compressing

• Google Photos or Drive link. Share a link rather than the file: original quality, no size limits, works everywhere.
• WhatsApp as a document. Attach it under Document rather than Gallery and it is sent untouched, up to 2 GB — no inline preview, but no re-encode either.
• Nearby Share / Quick Share. Phone to phone, no size limit, nothing uploaded.

Compressing on the phone

Plenty of Play Store apps do this, and the things to check before installing any of them are the same every time: does the free version watermark the output, is there a size or daily limit, does it upload your video to a server, and what permissions does it want? An app that needs full access to all your media to compress one file you picked is asking for more than the job requires — Android's photo picker exists exactly so it does not have to.

Or use this site, which needs no install

The compressor here runs in the browser on Android too. Chrome on a phone has far less memory to spare than a laptop, so keep it to clips of a couple of hundred megabytes or less, and prefer 720p output — but for the common case of "this clip is 40 MB and Discord wants 10", it works, and nothing is uploaded.

The one thing worth knowing: the first run downloads a 31 MB engine. On mobile data that is worth waiting for Wi-Fi.

What about the Video Compressor app?

The Android build exists but is not on Google Play yet. When it is, it will do what the iPhone version does: compress on the device, no upload, no ads. Until then, the browser tool above is the answer on Android.
