Unexpected images on allowed sites
A legitimate website can still contain a triggering advertisement, recommendation, thumbnail, or user upload.
Free Chrome image filter
A free NSFW image filter for Chrome
HAJR checks images as they appear in your browser and blurs images detected as explicit. Classification runs on your device, adding a visual safeguard on sites that cannot be covered by a domain list alone.
Part of the free HAJR Chrome extension. Not a separate download.
On-device classification
Image checks run inside the browser instead of uploading the images you view to HAJR for classification.
Adjustable sensitivity
Choose a stricter, balanced, or more lenient threshold based on the amount of filtering you want.
Dynamic-page coverage
HAJR watches for new images added after a page loads, which matters on feeds and continuously updating pages.
Part of a wider blocker
Use image blurring alongside known adult-site blocking, optional trigger-platform controls, and recovery statistics.
What this does
The short version.
HAJR's NSFW image filter is part of the free HAJR Chrome extension. It uses an on-device image-classification model to check sufficiently large images, blur those that cross the selected sensitivity threshold, and continue checking images added while a page is open. The feature is designed for people who want another layer between themselves and unexpected explicit imagery on search pages, forums, social platforms, or other image-heavy websites. It complements adult-domain blocking; it does not replace it. Automated classification can miss explicit material or blur an innocent image, so HAJR presents the feature as a safeguard rather than a guarantee.
Setup
Four steps, done while you are calm.
- 1
Install HAJR
Add the free HAJR extension from the Chrome Web Store and complete its setup.
- 2
Turn on Image Blur
Open HAJR settings and keep Image Blur Protection enabled.
- 3
Choose sensitivity
Start with the balanced setting, then adjust if you see too many misses or harmless images being blurred.
- 4
Keep domain blocking active
Image filtering works best as a second layer rather than the only protection.
When it helps
The moments this is for.
Image-heavy feeds
Dynamic feeds load new images continuously, so HAJR keeps checking additions instead of only scanning once.
Private, self-directed protection
The visual classification layer is designed to run locally rather than sending each viewed image to a remote classifier.
Good to know
Set it up knowing this.
- Automated image classification produces false positives and false negatives.
- An image may appear briefly before classification finishes, especially on a busy or fast-scrolling page.
- The feature filters browser images; it is not system-wide protection for every app on a computer.
- Websites change frequently, so filtering behavior should be tested and reported when something stops working.
Questions
Asked before installing.
Is the HAJR NSFW image filter free?
Yes. The image-filtering feature is currently included in the free HAJR Chrome extension, with no billing or paid plan integrated.
Does HAJR upload images for classification?
The current extension is designed to classify images locally in the browser. Account and accountability features use separate services, as described in the Chrome extension privacy policy.
Will it catch every explicit image?
No. Automated detection can miss content and can blur harmless images. Use it as one layer alongside adult-site blocking and other boundaries that fit your situation.
The other layers in the same extension
Turn it on before you need it.
Install once, switch on the layers that match your plan, and test them while you are thinking clearly.
