AI Object Detector
Detect objects in any photo with YOLO AI
Downloads once · Cached for offline use · Your image never leaves your device
🔒 Your image is processed entirely in your browser using YOLO AI. Nothing is uploaded to any server.
How to Use AI Object Detector
Upload your image
Drag and drop any JPG, PNG, or WebP image onto the tool, or click to browse. The image loads in your browser and is never uploaded to any server.
Load the YOLO model
Click Load YOLO Model to download the 22MB YOLOS-tiny model. It downloads once and is cached by your browser for instant offline use.
View detected objects
Click Detect Objects and the AI draws color-coded bounding boxes around every recognized object with labels and confidence scores. Download the annotated image as PNG.

How Browser-Based AI Object Detection Works
Traditional object detection services like Google Vision API or AWS Rekognition require uploading your image to cloud servers where GPUs run detection models. The AllTools AI Object Detector takes a different approach: it runs the YOLOS-tiny model directly in your browser using Transformers.js and ONNX Runtime Web. YOLOS (You Only Look at One Sequence) adapts the Vision Transformer architecture for object detection. The tiny variant is optimized for speed and browser deployment at just 22MB. When you upload an image, it is scaled to a maximum of 1280 pixels, fed through the model, and each detected object receives a bounding box with coordinates, a class label from the 80-category COCO dataset, and a confidence score. The entire pipeline runs locally — no pixel of your image ever leaves your device.
Use Cases for AI Object Detection
AI object detection is valuable across many scenarios. Content moderators scan uploaded images for specific objects or categories. Inventory managers photograph shelves and automatically count products. Accessibility developers generate image descriptions listing detected objects. Security analysts scan surveillance frames for people or vehicles. Educators demonstrate computer vision concepts with interactive examples. E-commerce sellers verify product photos contain the correct items. Photographers organize large image libraries by the objects they contain. Researchers annotate datasets for machine learning training. Because this tool runs locally, it is especially suited for sensitive images — security footage, medical imaging, unreleased products, or personal photos that should never be uploaded to third-party cloud APIs.
