How to blur NSFW images on Reddit and X (Twitter)
To blur NSFW images on Reddit and X, install NSFW Filter. It checks every image on the page with an AI model in your browser and blurs the explicit ones, so one extension covers Reddit, X, Google Images, and everywhere else at the same time, without touching each site’s own setting. Here is why that beats the built-in toggles.
Why the built-in blurs fall short
Reddit has an NSFW blur. X has a sensitive-media setting. Both help, and both have the same three limits.
They only cover their own content, so an image linked or embedded from another host can slip through. They are easy to toggle off and stay off. And they usually depend on you being logged in with the setting enabled. Miss any of those and the image is just there.
You also end up managing the same setting in five different places, one per platform, each with its own name and its own defaults.
One extension, every platform
NSFW Filter works below the platform. It reads the images on whatever page you are on and classifies each one on your device, then blurs the explicit ones. It does not ask Reddit or X what they think an image is; it looks at the image itself. So the same extension, with the same settings, covers every site at once. Here is how the on-device classification works .
On Reddit, that means explicit images get blurred whether they are posted directly, crossposted, or linked from a third-party image host, and whether or not you are logged in.
On X and Twitter, sensitive media gets blurred without depending on the account-level setting, so it holds up on other people’s posts and quoted media.
In Google Images, explicit thumbnails get blurred in the grid, which SafeSearch only partly addresses. More on that in SafeSearch isn’t enough .
Set it once
Pick your effect once, blur, grayscale, or hide, and it applies everywhere. If a particular site is all safe content and you would rather not filter it, allow-list it and NSFW Filter skips it there. Blur, grayscale, or hide covers those options.
It filters static images, not video, and it runs entirely on your machine. Free and open source.
Frequently asked questions
How do I blur NSFW images on Reddit?
Install NSFW Filter. It checks the images on any page in your browser and blurs the explicit ones, so it covers Reddit including crossposts and third-party image hosts, without relying on Reddit’s own NSFW setting.
Can one extension blur NSFW on Reddit and X at the same time?
Yes. Because NSFW Filter classifies images on the page rather than using each site’s setting, the same extension blurs explicit images on Reddit, X/Twitter, Google Images, and any other site at once.
Does it work if I am not logged in?
Yes. NSFW Filter reads the images on the page directly, so it does not depend on any account or per-site setting. It works whether or not you are signed in.
