DeniedPixels is a Safari extension that finds nudity on web pages and covers it before you see it. Images, video, GIFs and even explicit words in page text, censored in real time as you browse. Everything runs on your iPhone. Nothing is uploaded and no browsing data is collected. CHOOSE EXACTLY WHAT GETS COVERED 28 detection zones, each with its own toggle. Cover only explicit areas, or include faces, hands, feet and more. Set preferred sensitivity. Silhouette Masking covers a whole person along their outline instead of rectangles. 18 CENSORING STYLES Pixelate, Blur, Black Bar, Color Fill, Sticker, Noise, Glitch, Oil Paint, Redacted, Word Wall and Color Invert, plus seven animated styles: Static Noise, Scan Line, Spotlight, Shrinking, Permission Denied, Loading Bar and Pixel Wall. Every style is adjustable, and you can give each body part its own style. VIDEO, DONE PROPERLY Frame-accurate censoring that keeps up with playback, with minimum flickering or missing frames. Covers embedded video, GIFs and animated images. A loading placeholder keeps content hidden until it has been checked, so nothing flashes while a page loads. TEXT CENSORING Blacks out explicit words in page text. A built-in wordlist, your own additions, exceptions for medical or educational reading, and an on-device deep scan that catches writing which avoids obvious vocabulary. It never touches what you type. MODES Only Once: an image is permanently blocked after its first encounter. Decay: content degrades further each time you see it, until it is gone. Challenge: a number-guessing barrier before temporary access. Reverse: censor everything except the detected areas. Beta TV: the whole page pixelated, with one small window on the body part you chose. Red / Green Light: videos switch between visible and covered at random intervals, within limits you set. STAY LOCKED Self Lock puts your settings behind a password, a timer, or both. Shared Access lets someone you trust manage your settings remotely, and you can revoke it at any time. SITE BLOCKING A built-in blocklist of over 42,000 sites known for sensitive content, plus your own blacklist and whitelist. Or filter only on known sites and leave the rest of the web alone. PRIVACY All detection runs on your device with an on-device AI model. No images, URLs or browsing data are ever sent anywhere. ONE LICENCE, PHONE AND DESKTOP A subscription bought here also unlocks the desktop extension, so one purchase covers your phone and your computer. GETTING STARTED 1. Open Settings → Safari → Extensions (on iOS 18 and later: Settings → Apps → Safari → Extensions) 2. Enable DeniedPixels 3. Allow it on the sites you want covered 4. Browse Requires iOS 17 or later.

Your images and videos are never uploaded. No account, no tracking. NEW IN 1.6 • A built-in browser with the censor built in • Media Studio: censors your photos and videos for you • Full-body silhouettes from our own newly trained body model • Eye bars that turn with the face • A newly trained model, with new switches for hands, each eye, nose and mouth • Censoring that stays locked to images while you scroll • Up to 54 detections a second on iPhone 17 Pro WHAT IT DOES • Scans every image and video on the pages you open • 25 filter targets, from body parts to whole-body silhouettes • 18 censor styles • Censor entire media: any detection covers the whole photo or video, not just the detected area (Premium) • Reverse censor: blur the whole screen and see through only the regions it detects, with optional borders (Premium) • Videos the filter cannot read are fully covered instead of playing clear • Blocks navigation to NSFW domains entirely (editing the list needs Basic) MEDIA STUDIO • Censor a photo or video from your library. Nothing is uploaded and your original is never changed • Reads the whole clip first, so the boxes never trail behind • Fills the gaps when detection blinks and cleans up stray boxes • Fine-tune by hand: drag, resize or turn any box, draw one it missed, or change the look partway through • Photos are free. Video and Review and edit need Premium HOW YOU CONFIGURE IT • Pick what to filter: lower body, chest, buttocks, anus, faces, midriff, feet, underarms, eyes (one bar or each eye), nose, mouth, hands, whole body, and covered variants • Choose the look: Pixelated, Blur and Solid, plus Color Fill, Invert, Glitch, TV Static, Scanline, Spotlight, Cinema, Buffering, CRT, Dither, Chroma, ASCII, No Signal, BSOD and Frosted (Basic) • Custom text overlays per target (Basic) • Border style and padding per target (some border styles need Basic) • Save your favourite configurations as named presets (Basic) ADVANCED SAFETY FEATURES • Partner lock (Premium): a person you trust holds the key. Your settings lock the moment you turn it on, and switching it off needs a one-time code sent to their email, never yours. Their address is never stored, and a 7-day emergency reset covers you if they become unreachable. • Self-lock (Basic): password-protect Settings so you can't disable the filter on impulse • Challenge Mode (Basic): answer a trivia question to reveal a censored region briefly, refreshed daily • Only-Once Mode (Basic): any image you've blocked stays blocked forever, even if the detector misses it next time • 24-hour reset countdown if you forget the password, no shortcut LANGUAGES PixelBlocker is available in 10 languages.
