How do I remove the checkerboard background from AI-generated images?

Drop your image into NukeBG. It automatically detects painted checkerboard patterns from AI generators and replaces them with real transparency. Gemini watermark detection included. No upload needed — processing happens in your browser.

Can I remove the Gemini sparkle watermark for free?

Yes. NukeBG detects and removes Gemini's sparkle watermark automatically. It uses color deviation analysis to find the watermark and inpaints the area cleanly. Completely free, no sign-up required.

Are my images uploaded to a server?

No. NukeBG processes everything in your browser using WebGPU and WebAssembly. Your images never leave your device. The code is open source (GPL) so you can verify this yourself.

Does it work offline?

Yes. After your first visit, NukeBG caches all assets including the ML model via Service Worker. You can process images completely offline.

What AI generators does NukeBG support?

NukeBG removes backgrounds from any image — photos, illustrations, or AI-generated art. It includes specific detection for Gemini watermarks and painted checkerboard patterns.

How to remove background from image for free?

Open NukeBG in your browser, drop or paste any image, and download the result as a transparent PNG. It is 100% free with no account, no watermark on output, and no usage limits. The tool runs entirely client-side so there is nothing to pay for.

How to get transparent background without Photoshop?

NukeBG gives you a transparent PNG background without Photoshop or any installed software. It uses an ML model (RMBG-1.4) running directly in your browser to separate the subject from the background. Just drop your image and download the result.

Is NukeBG safe to use with private photos?

Yes. NukeBG is 100% client-side — your images are processed locally in your browser and never uploaded anywhere. There are no analytics, no cookies, and no tracking. The source code is open under GPL-3.0 so anyone can audit it.

How to remove painted checkerboard from AI image?

AI generators sometimes paint a fake checkerboard pattern instead of producing real transparency. NukeBG detects these painted checkerboard grids using classical computer vision, then replaces them with actual alpha transparency. Drop the image in and it handles it automatically.

Can I use NukeBG offline?

Yes. NukeBG uses a Service Worker to cache all assets including the ML model after your first visit. Once cached, you can remove backgrounds completely offline with no internet connection required.

What image formats does NukeBG support?

NukeBG accepts any image your browser can display — PNG, JPEG, WebP, GIF, BMP, and more. The output is always a PNG with true alpha transparency, which is the standard format for transparent backgrounds.

How to remove background from a screenshot?

Drop or paste your screenshot directly into NukeBG. It works with screenshots from any device — desktop, phone, or tablet. The ML model isolates the subject and produces a transparent PNG you can use anywhere.

Does NukeBG work on mobile?

Yes. NukeBG works in any modern mobile browser — Chrome, Safari, Firefox. The interface is responsive and you can upload images from your camera roll or files app. Processing may be slower on older phones since the ML model runs on-device.

Why does the model take time to load the first time?

The ML model (RMBG-1.4) is approximately 45 MB and needs to download on your first visit. After that, it is cached by the Service Worker so subsequent visits load instantly — even offline. The initial download is a one-time cost.

Is NukeBG really free? What is the catch?

NukeBG is genuinely free and open source under GPL-3.0. There is no catch — no premium tier, no watermarks on output, no account required. It runs entirely in your browser so there are no server costs to recoup. You can support the project on Ko-fi if you want to.

Can I use the resulting images commercially?

The tool itself is GPL-3.0, but the images you process are yours. NukeBG does not add watermarks or impose restrictions on your output. You can use the resulting transparent PNGs for any purpose — personal, commercial, or otherwise.
