ICQ – a simple way to communicate

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.
  • Offline user messaging,
  • 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.
  • Users can use emoticons while chatting with other users.
  • Large collection of free stickers for any occasion. Express your mood without words.
  • Variety of wallpaper to choose from.
  • Know when your message has been read – when your friend reads your message, a small avatar appears underneath it.
  • Cross-platform support – runs on Linux, Windows, and Mac OS X operating systems, as well as iOS, Android, and Windows phone.
  • Internationalization support: Chinese, Czech, English, French, German, Portuguese, Russian, Spanish, Turkish, Ukrainian, and Vietnamese languages are supported by the client.
