Download and install Opera
Download and install the desktop browser
To install the Opera desktop browser, just go to our download page and follow the simple instructions for the latest, official version.
32-bit or 64-bit?
For Mac, the 32-bit build has ceased from Opera 12. We are distributing a Universal Binary containing both 32-bit and 64-bit versions. This means all users on systems that supports 64-bit will use that, or otherwise fallback to 32-bit.
Regular 32-bit and 64-bit versions are available for Windows.
If you want to see what we’re currently working on, have a look at Opera Next.
More than one installation
If you are helping us by testing builds listed on the Opera Desktop Team Blog, you may need to change the installation options. As some of our experimental builds will upgrade your stable Opera by default, it’s a good idea to change the options to install it alongside your stable version instead.
For a second, separate installation, follow these steps:
You can either:
- Set up a new and distinct system account and download Opera using that account.
- Use an Opera Next build.
- Follow the instructions in the Multiple installations of Opera for Mac blog post.
For Mac users:
Opera will read your language settings from the System Preferences on first start-up and automatically apply an appropriate language file and set the preferred content language based on those settings. Please note that Opera is not available in all languages, and most websites may not be able to serve content based on your language setting.
For Windows and Linux users:
To select your preferred language for Opera and for content in webpages, go to.
If you have downloaded an Opera language file separately, go to the “Details” dialog to apply it. Once you have edited these preferences in Opera, your language settings will no longer be affected by changes to the system preferences.
Language in the opera.com website
If you are viewing our website www.opera.com, you can change the language for the site by using the selector at the bottom, left of the screen.
Start up tabs
To select which tabs Opera should open when you launch the browser, go to, or by pressing ⌘+F12 or Ctrl+F12.
Opera can start up with the tabs you had open when you last closed the browser, or can start with a previously saved session, or your home page. If you want to choose every time you launch Opera, enable the start-up dialog.
