Remove Background Online Free

Frequently asked questions

How do I remove the background from an image online?

Upload a JPG, PNG or WebP image. The first time you use the tool, the ML model will download and cache. Click "Remove background"; when processing finishes you see a preview and can download a PNG with transparent background. Everything runs in your browser.

Are my images sent to a server?

No. The library runs entirely in your browser using WebAssembly. Your image never leaves your device. The model is downloaded from a CDN and cached locally.

Why does the first run take longer?

The neural network model (ONNX) and WASM files are about 50MB. They are downloaded once and then cached by the browser. Subsequent runs are much faster.

What image formats are supported?

You can upload JPEG, PNG and WebP. The output is always PNG with transparency.

Does it work on mobile?

Yes, in modern mobile browsers that support WebAssembly. The first load may take a while on slower connections; processing may be slower on older phones.

Can I use the result commercially?

The library runs locally and produces a standard PNG. Usage rights depend on your source image and the library license; check the terms for commercial use.

What if the result has rough edges?

The model does its best to segment the subject. Complex backgrounds or fine details (hair, fur) may show minor artifacts. For critical work, consider refining in an image editor.

Is there a file size limit?

There is no fixed limit. Very large images use more memory and take longer. Practical limits depend on your device and browser.

Why PNG and not JPG?

PNG supports transparency (alpha channel), which is needed for "no background". JPG does not support transparency, so the output is always PNG.

Does it work in all browsers?

It requires a modern browser with WebAssembly. Chrome, Firefox, Safari and Edge (recent versions) are supported.
