Compress a video without uploading it

Phone videos and screen recordings are often far bigger than they need to be. Universal Converter re-encodes them with modern codecs such as H.265 and AV1, so they take much less space and still look good.

How to install and update

Open the downloaded .dmg and drag Universal Converter into Applications.
Open the app. The first time, macOS blocks it because it isn't signed by Apple: click Done.
Open System Settings > Privacy & Security, scroll down, click Open Anyway and enter your password. You only do this once.

Updates: if you allow it when the app first opens, it checks for new versions each time it starts, verifies their digital signature and installs them when you choose.

How to install and update

Tap Download for Android on your phone.

Updates: the app checks about once a day and tells you when a new version is ready. Download it the same way and install it over the old one; your settings are kept.

How to do it

Open Universal Converter and choose Video on the left.
Drag your files or a whole folder into the window, or click Add files.
Pick MP4 and move the quality slider down until the size suits you. Ready-made presets for phones, the web and archiving help.
Click Convert. The new files are saved next to the originals, or in the folder you choose.

Why do it offline?

Universal Converter does the work on your own device. Your files stay private, big files are no problem, and it works without an internet connection.
