Universal Converter Support

Universal Converter

Resize pictures or shrink them to a file size

Forms and email often limit the size of attachments. Universal Converter can shrink each picture until it fits a size you set, or resize it to exact pixels.

How to install and update
  1. Open the downloaded .dmg and drag Universal Converter into Applications.
  2. Open the app. The first time, macOS blocks it because it isn't signed by Apple: click Done.
  3. 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.

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.
