How to see mature (NSFW) content on Tumblr

Tumblr hides mature content by default. To see it, you need a Tumblr account with a birthday on file showing you are 18 or older. On the web, open Settings, go to "Content you see", and turn on "Show mature content". You can then also turn on "Blur mature content" to keep a click-to-reveal cover. The iOS app has no switch of its own, but it follows the setting you choose on the web.

This guide covers what Tumblr allows today, how its Mature label works, where the setting lives on each platform, and why some adults still cannot see labeled posts. It describes Tumblr's own settings only; it does not cover workarounds for age checks or regional restrictions.

What adult content Tumblr allows today

Tumblr allows nudity and other adult material again, but it still bans visual depictions of explicit sex acts. The Tumblr Community Guidelines say that "nudity and other kinds of adult material are generally welcome", while pictures, videos, GIFs, drawings or CGI of sexually explicit acts, or content with an overt focus on genitalia, are not allowed. Historically significant art of the kind found in a mainstream museum is an exception when it is properly labeled.

The policy has changed twice in recent years:

• December 17, 2018: Tumblr banned adult content, and existing flagged posts were made visible only to the person who posted them.
• November 2022: Tumblr reversed course and allowed nudity again, with labels so people can filter it.

In return, Tumblr asks creators to label mature posts so other users can filter them. Blogs that focus on mature content may also lose access to some features, including monetization options, because of payment partner policies.

How the Mature label works on Tumblr

Tumblr's Mature label is a catch-all for posts that are not safe for all audiences, covering sexual themes, drug and alcohol addiction and violence. According to Tumblr's Content Labels help page, every post defaults to "For Everyone", and the poster can switch it to Mature when creating, editing or reblogging.

Labels also come from Tumblr itself. Machine-learning classification and human moderators label posts that should carry one, and a blog that shares mature content without labeling it may be classified as Mature as a whole. Visitors to such a blog may see the notice "This content has been hidden due to its potentially mature nature."

What a labeled post looks like depends on the viewer's settings:

• Hidden: the default; the post does not appear for you.
• Blurred: the post shows with a cover you click or tap to reveal.
• Shown: the post appears like any other post.

In grid views on the web (Likes, Saved posts, blog recommendation cards), covered posts appear as gray tiles with a crossed-out eye icon. Mature posts on a blog's archive page are covered for every visitor, whatever their settings.

How to turn on mature content on Tumblr

The "Show mature content" setting is in your Tumblr account settings, and it is only available to signed-in users aged 18 or older. Tumblr merged its older per-category label options into two switches in March 2025, as noted on the Tumblr Support blog.

On the web:

1. Sign in to Tumblr and open Settings.
2. Open "Content you see".
3. Turn on "Show mature content". If you prefer a cover you click to reveal, also turn on "Blur mature content".

On Android, tap the account icon, then the gear icon, then Preferences and Content filtering, and switch on "Show mature content" (and the blur option if you want it).

On iPhone and iPad, the Tumblr app has no "Show mature content" setting. Change it on the web instead, then fully close and reopen the iOS app, and the web setting carries over.

If you have no full birthday on file, Tumblr lets you enter it once. Tumblr warns that a false birthday can lead to account termination, and depending on where you live, it may ask you to verify your age.

Why you cannot see mature content on Tumblr

If mature posts stay hidden even though you are over 18, one of a few conditions usually explains it. Tumblr's help page on content intended for mature audiences lists the rules behind them. Check them in this order:

1. You are not signed in. The mature content settings belong to an account, so logged-out visitors get the default (hidden) view.
2. Your account has no birthday, or the birthday shows you under 18. Under-18 accounts cannot see Mature posts, cannot click through to Mature blogs, and have their label settings locked until they turn 18.
3. The setting is still off. Check "Content you see" on the web.
4. You are on iOS. Change the setting on the web and restart the app.
5. Your own filters hide the post. Filtered tags and filtered post content (up to 200 filters) hide posts regardless of the mature setting.
6. Tumblr asks you to verify your age. Depending on where you live, Tumblr may require age verification, and you need to complete it through Tumblr's own prompt.

Search is a special case. Labels themselves do not remove posts from search or tag results, which follow your settings, but Tumblr says some mature content is intentionally not findable through search. A banner appears when your search results are filtered.

How the Tumblr NSFW settings used to work

Older guides, including earlier versions of this article, describe a Tumblr that no longer exists. From 2013, Tumblr flagged whole blogs as NSFW or Adult, kept adult blogs out of Tumblr search and third-party search engines, and offered a "Safe Mode" checkbox on the Dashboard settings page. Later, a padlock icon on the search results page toggled adult results for signed-in users.

Both controls are gone. They date from the period after Yahoo bought Tumblr in 2013. Today, post-level Mature labels and the two account switches replace blog flags and Safe Mode. If a guide tells you to look for Safe Mode or the padlock, it is out of date.

How to label or appeal mature posts on your own blog

Labeling your own mature posts keeps your blog from being classified as Mature as a whole. On the web, click the "For Everyone" button below the tags field while creating, editing or reblogging a post and switch it to Mature. In the app, tap the people silhouette icon and choose Mature. To label many older posts at once, use the Mass Post Editor on the web (Account, select the blog, Mass Post Editor); it can add labels but not remove them.

Labels applied by Tumblr's systems or moderators cannot be changed by you, but you can appeal them with the button at the top of the labeled post. If you find someone else's post that should carry a label, open the post's three-dot menu and choose "Request Content Label Review".
