How to remove a background

From a photo to a transparent cut-out in four steps — no upload, no watermark, no sign-up.

Drop your image

Choose or drag a PNG, JPG or WebP. It loads into a private in-browser workspace — your file never leaves the device.

Pick a model

Fast (quantized, ~45 MB) is quickest; High is full precision for cleaner edges. The model downloads once and is cached for next time.

Run on-device

The RMBG matting model runs with WebGPU (or WebAssembly), separating the subject from the background right in the tab.

Download the PNG

Compare before/after with the wipe slider, then download a transparent PNG ready to drop onto any new background.

Background remover — FAQ

How do I remove the background from an image for free?

Open the tool, drop an image, pick a model quality (Fast or High) and click Run. The subject is cut out and you download a transparent PNG — free, no account, in your browser.

Is my image uploaded to a server?

No. The AI runs on your own device with transformers.js (WebGPU, falling back to WebAssembly). Only the public model weights are downloaded once and cached; your image never leaves the browser.

What format is the result?

A PNG with a transparent background, so you can drop the subject onto any new background.

Which model does it use?

The open-source RMBG-1.4 matting model. A Fast (quantized, ~45 MB) and a High (full precision) preset are available.

Is there a watermark or sign-up?
