[FAQ] How do I add a command line switch to Opera

  • Sometimes it's necessary or helpful to start Opera with a command line parameter.
    This is how you do it (Windows):

    1. right-click the shortcut you normally start Opera with
      (1b right-click the Opera beta/developer entry if your shortcut is sitting at the taskbar)
    2. choose "Properties"
    3. In the Target-field add --name_of_the_switch=its_value behind the last "

    You can have a look at Chromium's command line switches. A lot of them will work in Opera, too. 😉

    Back to all FAQs

  • There is no 'Properties' option when you right-click on the taskbar, which is the only place the current Opera is.

  • What is the name of the switch for dpi adjustment?

    Good news folks. We have fixed running with custom DPI settings.

    Basically to run Opera with custom DPI use --alt-high-dpi-setting parameter. For example:

    100%: opera.exe --alt-high-dpi-setting=96
    125%: opera.exe --alt-high-dpi-setting=120
    150%: opera.exe --alt-high-dpi-setting=144
    200%: opera.exe --alt-high-dpi-setting=192
    250%: opera.exe --alt-high-dpi-setting=240

  • @jetro you need to execute 1b after 1 (it's the third item from the bottom).

    @genegold There's a dedicated FAQ especially for that :ninja:
