Privacy

Your photos never leave your device. The background remover decodes, segments and encodes every image client-side, in a worker thread inside the tab, and no part of the image (pixels, file name or metadata) is sent anywhere. This page lists every network request the tool does make, so you can check that for yourself.

What does the tool send over the network?

Request	When	What it contains	Image data?
AI model download from huggingface.co	When the page opens, until the model is cached (on Data Saver or a slow connection, when you add a photo)	A normal file download of the model weights, plus the 4.9 MB upscaler the first time you use AI upscale	No
Usage check to the Toolz.dev API	Each time you add photos	The tool id, a device fingerprint, and your login token if you are signed in	No
Usage record to the Toolz.dev API	After a run finishes	The same identifiers, plus how many photos were processed and the upscale factor	No
Sample photos from images.unsplash.com	Only if you click a sample	A request for that sample image	No
Site analytics (Google Analytics)	Page views, like every page on the site	The page you visited	No

The usage calls exist to apply the daily limit for guests. If they fail, for example because you are offline, the tool lets the run go ahead rather than blocking you.

You can confirm all of this in your browser's developer tools: open the Network panel, remove a background, and watch. The only large transfer is the model, and only the first time.

What is stored on my device?

• The AI model files, in Cache Storage under toolz-ai-models-v1 (about 98 MB or 46 MB).
• Your last settings, in local storage under toolz-bg-remover-settings-v1: background type and colour, size mode and values, crop, padding, upscale and format. Not your photos, and not a background image you picked.

Photos you add live only in the tab's memory. Closing the tab, removing an image or pressing Clear all releases them.

Is it safe for confidential photos?

Yes, as far as this tool is concerned: ID documents, unreleased products, client work and medical images are processed the same way as anything else, on your hardware, with nothing uploaded. The downloaded file is encoded fresh from a canvas, so it carries no EXIF metadata from the original, including GPS location. What you do with the file afterwards is up to you.

Can I remove backgrounds offline?

Removal itself needs no network once the model is in the cache: a cached model loads without a single request, and the usage check allows the run if it cannot reach the server. The page still has to load, so you need either a connection or a browser that has the page cached. If you plan to work offline, open the tool once while online and process one photo so the model is stored.

For background removal without any browser at all, the MCP server runs the same kind of model on your own machine from an AI assistant, also with nothing uploaded.

How is this different from a cloud background remover?

A cloud service receives your photo, runs its model on its servers, and sends a result back. That is often a larger model than a browser tab can hold, which is a real advantage on hard subjects, but it means your photo sits on someone else's server for at least as long as the job takes, under their retention policy. Here the trade goes the other way: the model is smaller, and the photo stays with you.
