ICQ – a simple way to communicate

Last Updated on April 17, 2022

ICQ is an open source instant messaging client.

This is an official Linux client. The latest update is in an experimental stage of development; there are some issues with users reporting memory leaks and instability.

The ICQ client includes software developed by the OpenSSL project for use in the OpenSSL Toolkit.

Features include:

  • History synchronization – conversation history in ICQ is now available on any of your devices.
  • Convert voice messages to text when you would rather read them.
  • Live chats.
  • High quality video chat.

  • Multi-user chats.
  • Free daily-limited SMS sending.
  • Share files – share photos, videos, music and any other type of files with your ICQ contacts. Resumable file transfers are available.
  • Use free texting even if your contact does not use ICQ. When you send a message, it’s delivered as a free SMS.
  • Greeting cards.
  • Searchable user directory.
  • Synchronize contacts using your mobile phone.
  • Compact mode.
  • Enable/disable sounds.
  • Notifications.

  • Variety of wallpaper to choose from.
