Free Vietnamese keyboard app

Unikey is the most popular, free Vietnamese keyboard for Windows. Once you’ve installed the program and set Vietnamese as your default language in Windows, you can write smoothly in this language. 

With support for text suggestions in Microsoft’s Edge browser, you have the convenience of typing in your chosen language. You can do this without having to engage in complicated, multi-key shortcuts to use the accents and special characters found in Vietnamese. If you’re looking for other multilingual keyboards, you can try Google Input Tools or EVkey.

Who created UniKey?

UniKey is an open-source program developed by Pham Kim Long for using a Vietnamese keyboard on a Windows device.


What is UniKey.EXE?

Although some .EXE files may be dangerous, UniKey.EXE is perfectly safe. It’s the executable file that forms part of the UniKey keyboard app on Windows.

How do I type in Vietnamese in Windows 10?

Install Vietnamese as a listed language in your device’s settings so that Windows recognises the input from the UniKey keyboard. Here’s how to do it in Windows 10:

  1. Press on the Windows start button in the bottom left of your screen or click in the search screen next to it
  2. Start typing ‘Add a language’
  3. When it appears in the search results under ‘Settings’, click on ‘Add a language to this device’
  4. Click on ‘Add a language’
  5. Start typing ‘Vietnamese’ in the search box, and click on it when it appears
  6. Click on the ‘Next’ button and select the desired option language feature
  7. Click ‘Install’

Does UniKey support the new Microsoft Edge?

UniKey has supported the new Chromium version of Edge for some time. However, the latest update has improved its performance by deleting or changing previous characters with suggested texts by Edge.

A different language

UniKey is a very small, open-source utility, so it doesn’t require many system resources. The only drawback is that it’s not updated very often, so you may have to wait a while for performance issues or other glitches to be fixed. Despite that, it’s ideal for writing in Vietnamese thanks to the app's speed, simplicity and reliability.
