Online background removers, and where your image goes.
Every one of these tools is a web page with a file picker. What separates them is mostly invisible: whether your image leaves your machine, how long it is kept, and what comes back down.
This site does not process images. The window below is an illustration.

Read itThe part you cannot see
Where the image actually goes
Two tools can look identical and work completely differently. For anything sensitive - a client's product, an unreleased design, a photograph of a person - this is the question that matters most, and it is answered in the privacy policy rather than the interface.
Processing
In your browser, or on their server
Some tools run the model locally using WebAssembly or the GPU, so the file never leaves the machine. Others upload it and send back a result. Both are legitimate; only one of them is private.
Retention
How long an upload is kept
Server-side tools usually state a deletion window. Anything from immediately after processing to indefinitely is in use across the category, and the answer is in the policy, not the FAQ.
Training
Whether your images improve their model
Separate from retention and often addressed separately in the terms. Sometimes it is opt-out, sometimes it applies only to the free tier, sometimes it is not mentioned at all.
Offline
Does it still work with the network off
The most direct test of the first question. A tool that keeps working once the page has loaded is doing the work locally, and one that stalls is not.
What happens to an uploaded image is one of the questions in the Background Removal Tool FAQ.
Limits
What the free tier is really capping
Free browser tools rarely limit the number of images. They limit something less obvious, and usually only say so after the result appears.
Output resolution
The most common cap. You upload a twelve-megapixel photograph and receive back something considerably smaller, at no point having been told this would happen.
Watermarking
Less common than it used to be on the cut-out itself, more common on any composited background the tool adds for you.
Input file size
A hard ceiling that rejects the file outright. Phone photographs in HEIC and anything from a full-frame camera are the usual casualties.
The format you get back
A tool that only exports JPEG cannot give you transparency at all, whatever the preview appears to show. Alpha needs PNG or WebP.

House rules
How this site is written
No invented numbers
No scores out of ten, no star ratings, no tier boards. Where something is better, it gets said in words and the reason is shown.
Only claims we can stand behind
Nothing describes a test that did not happen. Pricing and feature claims link to the vendor's own pages.
No paid placements
Nothing here is sponsored, and outbound links carry no affiliate tracking and earn no commission. No company pays to be included or to be written about more kindly.
The head-to-heads, such as Adobe Firefly vs Photoroom, are written to those rules.
Nothing above says which tools upload your images or what any of them keep. That is a question for each tool's own privacy policy. The comparisons set individual tools side by side, and the resources explain how the category works.
