Drag & drop a photo, or click to browse
JPG · PNG · WebP · Any size
Best results with portraits, product photos, and simple backgrounds. Very fine hair or transparent objects may not segment perfectly.
How it works
Upload your image
Drop any JPG, PNG, or WebP photo. It stays in your browser — nothing is sent to any server.
AI removes the background
The RMBG-1.4 model runs locally in a Web Worker. The first run downloads the model (~100 MB); every subsequent image is instant.
Download your result
Save as a transparent PNG or a JPG with a custom background colour. Use the slider to compare before & after.
How the AI Background Remover Works — Technical Details
SimpleTool uses the RMBG-1.4 model by BriaAI, distributed via the Hugging Face CDN and executed using Transformers.js v3 inside a browser Web Worker. The model runs via WebGPU on supported hardware (NVIDIA, AMD, Intel Arc, Apple M-series), with an automatic WebAssembly (WASM) fallback for CPU-only devices. No server connection is opened during image processing — all computation happens in local RAM.
The first use requires a one-time model download of approximately 100 MB. Subsequent images are processed instantly from the browser cache. The model generates an alpha mask which is applied via the Canvas 2D API using globalCompositeOperation: destination-in, producing a pixel-perfect transparent PNG in your browser without any round-trip to our servers.
