| # Browser Remove Background |
|
|
| Removes image backgrounds **entirely in your browser** — the image is decoded, |
| segmented and composited on your own device. Nothing is uploaded, no server, |
| no API key, no account. |
|
|
| Built with [ONNX Runtime Web](https://onnxruntime.ai/docs/tutorials/web/) running |
| the ISNet segmentation model (Apache-2.0), with both WASM and WebGPU execution |
| providers so you can measure the difference yourself. |
|
|
| ## Live demo |
|
|
| **[chenjindu.github.io/browser-remove-background](https://chenjindu.github.io/browser-remove-background/)** |
|
|
| A production version with a proper UI runs at |
| **[https://is.tools/remove-background](https://is.tools/remove-background)** — free, no |
| signup, no watermark, no size cap. |
|
|
| ## Run it locally |
|
|
| npx serve . |
| |
| Then open http://localhost:3000, pick a photo, and run inference with WASM and |
| with WebGPU to compare. |
|
|
| ## Benchmark |
|
|
| Measured on a desktop with a discrete GPU, Chrome 113+, 1024×1024 input: |
|
|
| | Execution provider | 2nd inference | |
| |---|---| |
| | WebGPU | ~0.6 s | |
| | WASM | ~17 s | |
|
|
| The first run is always slower — model download, session creation and shader |
| compilation. Read the second number. |
|
|
|  |
| *WASM — runs everywhere, roughly 25× slower.* |
|
|
|  |
| *WebGPU — Chrome/Edge 113+, sub-second after warm-up.* |
|
|
| ## Requirements |
|
|
| WebGPU needs Chrome or Edge 113+. Without it the page falls back to WASM, which |
| works in any modern browser but is roughly 25× slower on this model. |
|
|
| The model ships as three parts under `model/` and is reassembled in the browser, |
| which keeps every file under GitHub's size limit. |
|
|
| ## Part of is.tools |
|
|
| This probe came out of building [**https://is.tools**](https://is.tools) — a set of |
| browser-side tools for PDF, image, text and encoding work, built under one rule: |
| the file never leaves your device. |
|
|
| Same approach throughout: image codecs are MozJPEG / libwebp / libavif / OxiPNG |
| compiled to WASM, PDF work uses pdf-lib and qpdf, OCR uses tesseract.js, and |
| background removal uses the ISNet model in this repo. No accounts, no quotas, no |
| upload step, no watermark on the output. |
|
|
| Available in 8 languages. |
|
|
| ## License |
|
|
| Apache-2.0. The ISNet model is Apache-2.0 as well. |
