# NSFW Image Content Detector AI content-moderation classifier using NSFWJS to flag uploaded images as safe or potentially inappropriate. Built for moderation and compliance review of your own files — it analyzes uploads only and is not an image search or discovery tool. Supports JPEG/PNG/WEBP/GIF. > Canonical page: https://elysiatools.com/en/tools/nsfw-image-detector - **Category:** AI Tools - **Keywords:** nsfw, safety, content, moderation, ai, image, classification, flag, review, compliance, tensorflow ## Overview The NSFW Image Content Detector is an AI-powered content moderation tool that analyzes uploaded images to identify safe and potentially inappropriate visual material using NSFWJS and feature analysis. Designed for compliance review and pre-moderation workflows, it processes user-provided JPEG, PNG, WebP, and GIF files locally against adjustable sensitivity thresholds. ## Inputs - **Image File** (file): GIF files will analyze the first frame only. Supports transparency. - **Detection Sensitivity** (range): Lower values are more strict, higher values are more permissive - **Analysis Mode** (select): Select analysis method ## When to use - Auditing user-submitted profile avatars, cover photos, or forum attachments before publishing them live. - Checking ad creatives, marketing banners, and media assets against strict platform safety standards. - Testing and calibrating detection sensitivity thresholds for automated community moderation pipelines. ## How it works - Select and upload an image file in JPEG, PNG, WebP, or GIF format up to 20MB in size. - Choose an analysis mode such as Auto, Feature Analysis for fast checks, or NSFWJS Model for higher accuracy. - Adjust the sensitivity threshold from strict (0.1) to permissive (0.9) to match your moderation criteria. - Run the scan to receive structured JSON output containing content safety classifications and score probabilities. ## Use cases - Community managers vetting user-generated uploads before integrating them into a public media feed. - Compliance officers auditing uploaded digital marketing assets to prevent accidental platform policy violations. - Developers validating moderation thresholds against sample media sets prior to production deployment. ## Frequently asked questions ### What image file formats are supported? The detector supports JPEG, JPG, PNG, WebP, and GIF formats up to 20MB. ### How does the tool handle animated GIF files? GIF files are evaluated by analyzing only the first frame of the animation. ### What is the difference between the analysis modes? NSFWJS Model provides higher accuracy, Feature Analysis offers faster processing, and Auto combines NSFWJS with fallback mechanisms. ### How does adjusting the sensitivity threshold affect the results? Lower values (e.g., 0.1 to 0.3) enforce strict moderation, while higher values (e.g., 0.7 to 0.9) are more permissive. ### Can this tool search the web for inappropriate images? No, the tool operates strictly as a classifier for individual files you manually upload. ## Related tools - [Image Color Extractor](https://elysiatools.com/en/tools/image-color-extractor): Extract dominant colors from images using various algorithms including k-means clustering and histogram analysis - [Image Difference](https://elysiatools.com/en/tools/image-difference): Calculate the difference between two images to identify changes or create comparison masks - [Batch Image Convert](https://elysiatools.com/en/tools/batch-convert): Convert multiple images to different formats with quality settings and batch processing - [Data URI Generator](https://elysiatools.com/en/tools/data-uri-generator): Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown - [Add Border to Image](https://elysiatools.com/en/tools/image-add-border): Add customizable borders to images with various styles, colors, and widths - [Add Frame to Image](https://elysiatools.com/en/tools/image-add-frame): Add decorative frames to images with various styles like classic, modern, vintage, and custom designs - [Add Glow Effect](https://elysiatools.com/en/tools/image-add-glow): Add beautiful glow effects to images with customizable color, intensity, size, and style variations - [Image Gradient Overlay](https://elysiatools.com/en/tools/image-add-gradient): Add gradient overlay effects to images with customizable colors, directions, and blend modes ## Samples - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Web Image Processing TypeScript Samples](https://elysiatools.com/en/samples/web-image-processing-typescript): Web TypeScript image processing examples including image read/save, scaling, and format conversion - [Android Image Processing Java Samples](https://elysiatools.com/en/samples/android-image-processing-java): Android Java image processing examples including reading/saving images, scaling, and format conversion - [Android Image Processing Kotlin Samples](https://elysiatools.com/en/samples/android-image-processing-kotlin): Android Kotlin image processing examples including reading/saving images, scaling, and format conversion
