NSFW Filter 2026

Free, open source, and privacy-focused browser extension to block "not safe for work" content.

NSFW Filter 2026 uses on-device machine learning to automatically detect and blur or hide not-safe-for-work images as you browse — no images are ever uploaded or sent to any server. FEATURES • Runs entirely on your device — your browsing is completely private • WebGPU-accelerated inference for fast, low-CPU classification • Choose between blur or hide effects • Adjustable sensitivity threshold • Works on all websites including pages that are just a single image • Manifest V3 — built to the latest Chrome extension standard HOW IT WORKS Each image is classified locally using a TensorFlow.js neural network (MobileNet v2 or InceptionV3). If the confidence score exceeds your chosen threshold, the image is blurred or hidden instantly. No network requests are made for classification. PRIVACY No images, URLs, or personal data are collected or transmitted. All processing happens locally in your browser. OPEN SOURCE NSFW Filter 2026 is free and open source under the GPL-3.0 license.
