Dark Theme for Chrome: Best Free Themes to Try in 2025

How to Install a Dark Theme for Chrome (Step‑by‑Step)Dark themes reduce glare, can extend battery life on OLED/AMOLED screens, and often look cleaner. This guide walks you through multiple ways to add a dark theme to Google Chrome on desktop and mobile, including built-in options, official themes from the Chrome Web Store, third‑party extensions, and how to create a custom theme. Each method includes step‑by‑step instructions, troubleshooting tips, and short notes about privacy and performance.


Overview: Which option should you choose?

  • Built‑in dark mode — easiest; integrates with your OS and won’t add extensions.
  • Chrome Web Store themes — simple visual changes without extra permissions.
  • Extensions (e.g., dark readers) — most flexible (force‑darken pages, schedule, per‑site settings) but require permissions.
  • Custom themes — personalized colors and images; more advanced.

1. Use Chrome’s built‑in dark mode (Windows, macOS, Linux)

Chrome follows your operating system’s appearance on desktop. Enabling dark mode in your OS will usually switch Chrome to dark toolbars, menus, and UI.

Windows 10 / 11

  1. Open Settings (Win + I).
  2. Go to Personalization > Colors.
  3. Under “Choose your color,” pick Dark (or Custom > choose Dark for “Default Windows mode” and/or “Default app mode”).
  4. Restart Chrome if it doesn’t switch automatically.

macOS (Mojave and later)

  1. Open System Settings (or System Preferences) > Appearance.
  2. Select Dark.
  3. Chrome should follow the change. Use “Auto” to switch with time of day.

Linux (GNOME/KDE)

  • Switch to a dark theme in your desktop environment’s Appearance settings. Behavior may vary by distro and Chrome build.

Note: The built‑in dark mode affects Chrome’s interface (tabs, address bar, menus). It does not force websites to display in dark mode.


2. Force dark mode for web contents (desktop Chrome experimental flag)

Chrome has an experimental flag to force a dark theme on web contents. This can invert colors on many sites, useful when sites lack native dark modes.

  1. In Chrome’s address bar type: chrome://flags
  2. Search for “Auto Dark Mode for Web Contents” or paste: chrome://flags/#enable-force-dark
  3. Set the dropdown to Enabled (there are multiple modes like “Enabled with selective inversion” — try different ones if colors look odd).
  4. Click “Relaunch” to restart Chrome.

Caveats:

  • Experimental flags may cause rendering issues.
  • Some images or websites may look incorrect; try different flag modes or disable if problems occur.

3. Install an official theme from the Chrome Web Store

Themes from the Chrome Web Store change Chrome’s appearance without adding runtime permissions.

  1. Open Chrome and visit the Chrome Web Store: chrome.google.com/webstore
  2. In the left menu choose “Themes” or search for “dark theme for Chrome.”
  3. Browse themes — popular choices include “Just Black” (official Google theme) and other AMOLED‑style themes.
  4. Click a theme you like, then press Add to Chrome.
  5. Chrome will apply the theme immediately. To revert, go to Settings > Appearance > Reset to default theme.

Privacy: Themes do not require special permissions because they only change UI visuals.


4. Use a dark‑mode extension (best for content darkening)

Extensions like Dark Reader offer powerful, configurable dark modes that transform page content (backgrounds, text, images).

  1. Open the Chrome Web Store and search for “Dark Reader” or “Dark Mode.”
  2. Click the extension, then choose Add to Chrome and accept permissions.
  3. After installation, open the extension icon (top‑right of Chrome).
  4. Toggle the extension on, choose “Dark” mode, and adjust settings: brightness, contrast, sepia, font‑scale, and site‑specific rules.
  5. Use the site list to disable darkening on particular pages (banking sites or image‑heavy pages where inversion breaks layout).

Permissions note: Content‑modifying extensions need access to page data to transform styles; install only from trusted developers and check reviews.


5. Create a custom Chrome theme (simple method)

If you want specific colors or a background image for your new tab page, you can create a theme quickly with Google’s Theme Creator websites or by making a small extension.

Option A — Use an online theme creator

  1. Search for “Chrome Theme Creator” and open a reputable site (e.g., ThemeBeta).
  2. Upload a background image, set toolbar and frame colors, and preview.
  3. Download the generated CRX (Chrome theme) file or follow site instructions to add it to Chrome.
  4. Install by dragging the CRX into chrome://extensions (Developer mode must be enabled) or follow the site’s one‑click install.

Option B — Build a theme manually (developer method)

  1. Create a folder with a manifest.json and images. Example manifest.json:
    
    { "manifest_version": 2, "name": "My Dark Theme", "version": "1.0", "theme": { "images": { "theme_frame": "images/frame.png" }, "colors": {   "frame": [34,34,34],   "toolbar": [20,20,20],   "tab_text": [255,255,255],   "bookmark_text": [200,200,200] } } } 
  2. Go to chrome://extensions, enable Developer mode, click Load unpacked, and select the folder.
  3. To publish, pack and upload to the Chrome Web Store per Google’s developer docs.

6. Mobile Chrome (Android & iOS)

Android (Chrome)

  1. Open Chrome. Tap the three dots > Settings > Theme.
  2. Choose Dark (or System default).
  3. To force dark for pages: chrome://flags > search “dark mode” > enable “Android Web Contents Dark Mode” (flag names vary by version). Relaunch.

iOS

  • Chrome on iOS follows the system appearance. Set iOS to Dark in Settings > Display & Brightness. Chrome will switch to dark UI. Web content darkening is limited due to platform restrictions—use site‑specific dark themes when available or Reader Mode for articles.

7. Accessibility and readability tips

  • Increase font scale or use reader mode for text heavy pages.
  • For OLED screens, choose true black themes to save battery.
  • If images invert poorly, whitelist the site in your dark extension.
  • Use high contrast settings if you have low vision.

8. Troubleshooting common issues

  • Theme not applying: go to Settings > Appearance and click “Reset to default theme,” then reinstall.
  • Pages look garbled with forced dark flags: disable the flag or try a different inversion mode.
  • Extension conflicts: disable other style or accessibility extensions to isolate issues.
  • Sync problems: Chrome sync can restore previous theme settings; check chrome://settings/sync.

9. Privacy and performance considerations

  • Themes from the Web Store are safe and don’t need special permissions.
  • Extensions that modify content need page access; prefer well‑reviewed extensions and check privacy policies.
  • Extensions may slightly increase memory usage; lightweight themes have negligible impact.

10. Quick recap (step‑by‑step short checklist)

  • For interface only: enable OS dark mode or install a Chrome Web Store dark theme.
  • For web pages too: install Dark Reader or enable Chrome’s “Auto Dark Mode for Web Contents” flag.
  • For custom visuals: use an online theme creator or build a theme and load it as unpacked.
