Opera浏览器起初是一款挪威Opera Software ASA公司制作的支持多页面标签式浏览的网络浏览器，由于新版本的Opera增加了大量网络功能，官方将Opera定义为一个网络套件。兼容Windows 10系统。

Opera支持多种操作系统，如Windows、Linux、Mac、FreeBSD、Solaris、BeOS、OS/2、QNX等，此外，Opera还有手机用的版本，在2006年更与Nintendo签下合约，提供NDS及Wii游乐器Opera浏览器软件；也支持多语言，包括简体中文和繁体中文。

Opera还提供很多方便的特性，包括Wand密码管理、会话管理、鼠标手势、键盘快捷键、内置搜索引擎、智能弹出式广告拦截、网址的过滤、浏览器识别伪装和超过400种，可以方便下载更换的皮肤，界面也可以在定制模式下通过拖放随意更改。下载一个大约10M的扩展以后，它甚至可以让你用语音控制以及阅读网页（英文）。而以上的这些，包括右键菜单都是可以由用户自定义的。

Opera支持包括SSL 2/3以及TLS在内的各种安全协议，支持256位加密，可以抵御恶意代码攻击、钓鱼攻击等网络攻击。而其网页渲染速度也是当今速度最快的。它支持W3C标准 ,此外它还可以作者模式和用户模式让有经验的使用者控制浏览网页的结构和字体等。
