Add to Chrome — It's Free Does AO3 have dark mode?Why it mattersWhy Fic Readers Switch to Dark Mode
Archive of Our Own's default theme is bright white — great in daylight, harsh at 2am when you're three chapters deep into a fic you can't put down. A lot of readers land here after typing "ao3 dark mode" into Google specifically because of eye strain during long, late-night reading sessions.
A dark theme lowers the overall brightness and contrast of the page, which is generally more comfortable for extended reading in low-light conditions, especially on OLED phone and laptop screens where a true-black background can also save battery. AO3 Dark Mode was built around that use case first — every default is tuned for reading a long work start to finish, not just glancing at a single page.
The short answerDoes AO3 Have a Dark Mode?
Not by default for every reader. Archive of Our Own supports site skins — including a built-in dark skin called "Reversi" — but skins live inside Preferences → Skins, which means you first need to create and log into an AO3 account before you can turn one on. If you've ever searched "does AO3 have dark mode" hoping for a simple toggle, that's why you didn't find one: AO3's dark option is account-gated, not a site-wide setting.

AO3 skins dark vs. an extensionAO3 Dark Skins or a Dark Mode Extension?
AO3's community has built plenty of dark AO3 skins over the years — custom CSS you paste into your account's skin settings. They work, but they come with tradeoffs worth knowing before you go looking for "ao3 skins dark" on Tumblr or a skins archive.
| Community dark skins | AO3 Dark Mode extension | |
|---|---|---|
| AO3 account required | Yes | No |
| Setup | Copy/paste CSS into Preferences | One-click install, one-click toggle |
| Breaks on AO3 redesigns | Sometimes, until the skin author updates it | Maintained independently of any one skin |
| Extra reading controls | Skin-dependent | Font, size, width, brightness, contrast built in |
| Works while logged out | No | Yes |
If you already have a favorite AO3 skin and it's working for you, that's great — skins and this extension aren't mutually exclusive. But if you want dark mode without the account and setup step, the extension is the faster path.

Before you installCompatibility & Requirements
A few practical details people usually ask before installing:
| Browser | Supported |
|---|---|
| Google Chrome (desktop) | Yes — official support |
| Microsoft Edge, Brave, and other Chromium browsers | Yes — any browser that supports Chrome extensions |
| Chrome on Android | No — Chrome for Android does not support extensions |
| Safari (macOS/iOS) | No — different extension format, not currently supported |
| Firefox | Not yet available |
On mobile, your best options for a darker AO3 are your phone's OS-level "force dark" or reader-mode feature, or an AO3 skin if you're logged in. On desktop Chrome (or any Chromium browser), AO3 Dark Mode is the fastest way to get there.
Frequently askedAO3 Dark Mode FAQ
Does AO3 have a dark mode?
Not a site-wide toggle for everyone. AO3 offers a built-in "Reversi" dark skin, but it's only accessible to logged-in users through account Preferences. AO3 Dark Mode brings the same idea to every visitor, account or not.
How do I get dark mode on AO3 without an account?
Install the AO3 Dark Mode Chrome extension. It applies dark mode directly in your browser, so it works whether or not you're logged into AO3.
How do I turn on dark mode on AO3?
Add the extension, click its icon while on archiveofourown.org, and choose a theme. Dark mode applies immediately, with no page reload or settings menu required.
What's the difference between AO3 dark skins and a dark mode extension?
Skins are AO3-account CSS you configure manually and which can break when AO3 changes its layout. The extension works at the browser level, needs no account, and includes reading controls skins don't typically offer.
Is AO3 Dark Mode free?
Yes — no subscription, no paywall, no account requirement.
Does AO3 Dark Mode collect my data?
No. There's no analytics or tracking, and your AO3 credentials or story content are never read or transmitted. Preferences are stored locally via Chrome's extension storage.
Does AO3 Dark Mode work on mobile?
Not currently. Chrome for Android and iOS Safari don't support desktop-style browser extensions, so AO3 Dark Mode is available for desktop Chrome and other Chromium-based browsers (Edge, Brave, etc.) only.
Will AO3 Dark Mode work with my AO3 skin?
It can, but the two aren't designed to be layered. If you already use a custom AO3 skin, we'd recommend picking one or the other to avoid conflicting styles — the extension is built for readers who don't want to manage a skin at all.
Does the dark theme work on the "New Work" posting and editing page?
Yes. AO3 Dark Mode applies its theme to the work-editing page as well as reading pages, so writing and posting stay dark too.
