Why we built it

Background removal is a solved problem with an unsolved privacy story. Nearly every free tool uploads your image to a server, processes it there, and returns a result — which is fine for a stock photograph and considerably less fine for a product shot before launch, an identity document, or a photograph of a colleague.

Background Remover Pro does the processing on your own machine. The image is never transmitted because there is no endpoint to transmit it to. It also handles watermark removal on images you have the right to edit, which is the second request we heard constantly and which almost no local tool offers.

For anyone handling commercially sensitive or personal images, that distinction is the entire point of the tool.

The problem it solves

Marketing teams, small e-commerce sellers and anyone preparing listings need cut-outs constantly, and the friction is real: upload, wait, download, discover the free tier watermarked it, repeat.

For businesses there is a second problem that rarely gets discussed. Uploading a product image to an unknown third-party service before a launch is a genuine information-security decision that nobody consciously makes — they just need a cut-out and the tool is right there.

Privacy commitments

  • Images are processed entirely on your device — nothing is uploaded.
  • Works fully offline once installed; the model is bundled rather than fetched.
  • No account, no sign-in, no identifiers.
  • Processed images are held in memory and discarded when the tab closes.

Permissions and why

  • activeTabLets the extension read an image you have explicitly right-clicked. It has no access to pages you have not acted on.
  • contextMenusAdds the right-click option on images.
  • downloadsSaves the exported image to your machine.
Features

What it actually does

On-device processing

Segmentation runs locally in the browser. The image never leaves your machine, and the tool works with no network connection at all.

Watermark removal

Content-aware fill for watermarks and small unwanted objects on images you have the right to edit.

Right-click on any image

Works on images already on a page as well as on files you open, so there is no download-then-upload cycle.

Transparent PNG export

Clean alpha channel suitable for compositing, with no matte fringe on typical product photography.

Solid or gradient replacement

Swap the background for a colour or a simple gradient without opening a separate editor.

No watermark, no limit

No usage cap, no watermark on the free output, and no account.

How to use it

Three steps, no configuration

011

Open an image

Right-click any image on a web page, or open a local file through the extension popup.

022

Remove and refine

The subject is detected and the background removed. Adjust edge softness if the subject has fine detail, or brush over a watermark to clear it.

033

Export

Download as a transparent PNG, or replace the background with a colour first.

Questions

About Background Remover Pro

Including where another tool would serve you better. If you have found a bug or want a feature, tell us on WhatsApp — we read every message.

For clear subjects on distinguishable backgrounds — product shots, people, objects on plain surfaces — it is comparable. Dedicated paid services still have an edge on very fine detail such as wispy hair against a busy background, because they run larger models on server hardware. The trade is quality at the margin against your image never leaving your machine.

That depends entirely on the image and is your responsibility rather than ours. The feature exists for removing watermarks from images you own or are licensed to edit — your own product photography returned from a stock service, or a proof you have since purchased. We do not encourage using it on work you have no rights to.

Yes, once installed. The processing model is bundled with the extension rather than fetched, so it works on a plane or behind a restrictive firewall.

It handles JPEG, PNG and WebP. Very large images — above roughly 6000 pixels on a side — are downscaled before processing to keep it responsive on modest hardware, and you can export at the processed resolution.

Behind this extension

How we build and keep a published extension alive

Background Remover Pro is built natively on Manifest V3 rather than ported from the older extension architecture, and that distinction matters more than it sounds. Manifest V3 replaced persistent background pages with ephemeral service workers that the browser is free to shut down at any moment. An extension written on the old assumptions works perfectly on a developer’s machine and behaves unpredictably on a user’s machine after their laptop has been asleep for four hours.

So state is persisted to storage and restored rather than held in memory, anything that must survive a worker restart uses an alarm rather than a timer, and long operations are structured as resumable steps. Where network behaviour is modified, it uses declarative rules evaluated by the browser rather than a JavaScript listener on every request — which is why the extension adds no measurable per-request cost to your browsing.

Permissions are the part users are right to scrutinise, and we design for the narrowest set that makes the feature work. Anything optional is requested at the point of use rather than at install, which is both more honest and, for a public extension, materially better for install conversion. Every permission this extension holds is listed on this page with the specific reason it exists.

Maintenance is the unglamorous half. Chrome ships changes on a six-week cadence, target sites change their markup without notice, and Web Store policy is updated periodically with limited warning. We monitor for breakage, publish fixes promptly, respond to reviews, and keep the listing compliant. An extension that is abandoned becomes uninstallable within about two years as platform requirements move — so we treat publishing as a commitment rather than a launch.

We maintain seven live extensions for exactly this reason: it is how we stay genuinely fluent in Manifest V3 behaviour, review policy and the operational reality of shipping to real users — which is what we then bring to the extensions we build for businesses.

Engineering notes

  • Manifest V3 native — service worker lifetime assumed, never persistent state in memory.
  • Declarative rules for any network behaviour, so there is no per-request JavaScript cost.
  • TypeScript throughout, with schema validation at every boundary where data enters.
  • Optional permissions requested at the point of use rather than at install.
  • Bundled dependencies — no remotely hosted code, which MV3 prohibits and reviewers check.
  • Chrome and Edge from one build; Firefox needs a compatibility layer, Safari a native shell.

Want this for your team?

If your staff retype data out of a supplier portal, a government site or a marketplace dashboard, the same engineering applies. A focused internal tool is typically three weeks, deployed through enterprise policy so it installs automatically and cannot be removed by users.

Next step

We build extensions for businesses too.

If your team retypes data out of a supplier portal, a government site or a marketplace dashboard, that is usually three weeks of work and hundreds of hours a year recovered.
