How to Change Theme in Instagram PC or Browser

Instagram has become one of the most popular social media platforms, not just on smartphones but also via PC or web browsers. While mobile users enjoy a variety of customization options, many browser users often wonder if it’s possible to personalize their Instagram experience—including changing the theme between light and dark mode. In this guide, readers will learn how to change the theme in Instagram when using a PC or browser, whether for reducing eye strain or just personal aesthetic preference.

TLDR (Too Long, Didn’t Read)

Changing the theme on Instagram via PC or browser is possible and quite straightforward. Users can switch between light mode and dark mode directly within the platform’s interface or by adjusting their system or browser settings. Instagram typically mirrors the system’s appearance settings, but manual overrides can also be applied. Read on for step-by-step instructions and answers to common questions.

Why Change the Theme on Instagram for PC?

There are several reasons why someone might want to switch between light and dark themes while using Instagram in a browser.

  • Eye Comfort: Dark themes reduce glare, especially in dim environments.
  • Battery Life: Dark mode can help conserve battery if you’re using a laptop.
  • Aesthetics: Some people simply prefer the look and feel of one theme over the other.
  • Consistency: Users who’ve set their devices to a default theme may want all their apps to match it, including Instagram.

How to Change Instagram Theme in PC or Browser

Instagram’s browser version currently offers theme customization, although it’s somewhat limited compared to the mobile app. Below are the different methods one can use to swap between light and dark mode on Instagram’s web interface.

Method 1: Use Instagram’s Built-in Theme Switch

  1. Open your browser and go to Instagram.com.
  2. Log in to your account if you haven’t already.
  3. Click on your profile picture at the top right corner to access the menu.
  4. Select “Settings” from the dropdown list.
  5. In the Settings panel, look for a “Switch Appearance” button or theme toggle option.
  6. Click to switch between Light and Dark Mode as desired.

This method is the easiest and most direct if Instagram offers the theme switch option in your region or device type. It syncs instantly and affects only Instagram, not your entire browser or system theme.

Method 2: Set Browser or System Preferences

If the built-in Instagram toggle isn’t available, Instagram might automatically follow your system’s or browser’s appearance settings instead. Here’s how to force dark mode through system settings.

For Windows 10/11:

  1. Open the Settings menu.
  2. Navigate to Personalization > Colors.
  3. Scroll down and choose Dark under “Choose your default app mode.”
  4. Refresh your Instagram tab in your browser.

For macOS:

  1. Go to System Preferences.
  2. Click General.
  3. Under Appearance, select Dark.
  4. Reload Instagram in your browser to see the changes.

Changing your system theme will often prompt compliant websites (like Instagram) to adopt the same visual style automatically. However, this affects all applications using the system theme setting.

Method 3: Force Dark Mode Using Browser Extensions

If neither of the above options works, or you want more control, try using browser extensions. Several browser add-ons force websites to display in dark mode regardless of their native theme settings.

Recommended Extensions:

  • Dark Reader: Available on Chrome, Firefox, Safari, and Edge. Offers advanced filtering and toggle options per site.
  • Night Eye: Applies dark mode to non-compliant websites while maintaining readability.
  • Super Dark Mode: Simple and light add-on primarily for Chrome users.

To use these extensions:

  1. Go to your browser’s extension or add-on store.
  2. Install the preferred dark mode plugin.
  3. Enable it and configure rules for Instagram.com.
  4. Refresh your Instagram page. The dark theme should now appear.

Things to Keep in Mind

  • Instagram UI Updates: Instagram frequently updates, and appearance settings may shift locations or become unavailable without notice.
  • Region-Based Features: Some theme features are tested in specific countries before a global rollout.
  • User Preferences: When using browser extensions, make sure the dark mode styling doesn’t interfere with usability or visibility of your IG feed and DMs.

Troubleshooting Theme Issues

If your theme isn’t changing or keeps reverting:

  • Clear your browser cache: Cached data can prevent theme changes from applying.
  • Update your browser: Ensure your browser is up to date to support advanced site-set UI features.
  • Disable conflicting extensions: Ad blockers or interface modifiers may interfere with theme settings.

Benefits of Using Dark Mode on Instagram

Whether you’re browsing during late hours or conserving power while running multiple tabs, the dark mode on Instagram brings practical advantages:

  • Less eye fatigue during extended browsing sessions.
  • Improved readability in low-light environments.
  • Increased device battery savings, especially on OLED displays.
  • Stylish and modern interface appearance.

Conclusion

Switching themes on Instagram for PC or through a browser isn’t just about looks—it’s about comfort, accessibility, and control. Whether using Instagram’s native features, modifying system settings, or relying on helpful browser extensions, users can customize their experience with a few easy steps. As the platform evolves, additional theme options may become more robust, giving users even greater flexibility.

FAQ

Yes, if the feature is available in your region or account settings, you’ll find a theme switch option in Instagram’s settings menu on the web version.

Q2: Why don’t I see the theme toggle in Instagram settings?

Instagram may not have rolled out the built-in theme toggle in your region, or you might be using an outdated browser. Try updating your browser or using alternative methods like changing system appearance or installing dark mode extensions.

Q3: Will changing my computer’s theme affect other websites too?

Yes, if you change your system or browser theme, other compliant websites may follow that preference. However, third-party extensions can control theme changes for only specific websites like Instagram.

Most popular extensions from trusted sources (like Dark Reader) are safe to use. Always read reviews and check permissions before installing any extensions.

Q5: Does Instagram’s theme setting sync across devices?

No, changing the theme in the browser won’t affect the mobile app or other devices. Each platform must be set individually.
