Remove the background from an image, right in your browser

No. The image is read with the browser's File API and processed on your device, and the page never sends it anywhere. Every file the page requests, and the one thing it can send (an error report, without your image), is listed in what the site receives and how to check it.

The first image takes longer, because your browser downloads the AI model (about 176 MB) and the WebAssembly engine and starts them. Later images in the same tab skip that step, since the engine stays running, and on a later visit the model loads from your device while your browser keeps it. After that, in the engine's own benchmark on a cloud server with 4 virtual CPUs in headless Chrome, one image took 14 to 16 seconds with four threads and about 30 seconds with the single-threaded CPU build. Your time depends on your processor. When your browser gives the page a graphics card through WebGPU, the model runs there instead, and we have not measured that speed yet; if the graphics card cannot start the model, the page switches to the processor on its own. How it works lists the CPU measurements.

Yes, up to 20 at a time. Choose or drop several images together, and the page removes each background on your device, one after another, without uploading them. One Background, Format, and Size choice applies to all of them (you can change it afterwards without running the model again), and "Download all (ZIP)" saves every finished image in one file; each finished image also has its own Download link in its row. A batch of 20 takes about 5 minutes on a processor like the one in the engine's benchmark, a cloud server with 4 virtual CPUs where one image took about 14 to 16 seconds (an illustrative estimate, 20 x 14 to 16 seconds). The one-time model download comes on top on a first visit. On a phone or tablet, save each image as it finishes: with little free memory the batch may stop partway, and some phones reload the tab instead, which clears the batch.

Choose or drop a JPEG, PNG, or WebP; AVIF, GIF, and BMP usually work too. The result is a PNG with a transparent background, or, on white or a color you choose, a PNG or a smaller JPG.

Yes. After the background is removed, choose Transparent, White, or pick any color, and the preview updates instantly without running the model again. The colored version is composed on your device and downloads as a PNG or, if you prefer a smaller file, a JPG. Replacing the background with another photo is not supported.

It may. In our measurement in desktop Chromium on a computer with 4 virtual CPUs, the browser tab used about 1.2 GB of memory for a typical photo and up to about 1.6 GB for a 16-megapixel photo, so phones and tablets with little free memory can fail. The page tells you when it can detect this; on some phones the browser reloads the tab instead. We have not tested it on real phones yet, so a computer is the safer choice. On an iPhone or iPad, the built-in tools may be enough: see removing a background on a Mac, iPhone, or iPad.

No. The page needs a connection to load, and there is no offline mode. The AI model is kept in your browser after the first image, though, so later visits skip the 176 MB download for as long as the browser keeps it.

Images larger than 16 megapixels are scaled down before processing, so the image you download is at most 16 megapixels. Larger photos also need more memory: in our measurement in desktop Chromium on a computer with 4 virtual CPUs, the browser tab used about 1.2 GB for a typical photo and up to about 1.6 GB for a 16-megapixel photo, which some phones do not have free.
