How it works
- 1
A model downloads
RMBG-1.4, fetched into your browser once and cached. ~45 MB.
- 2
Your GPU runs it
WebGPU finds the subject and produces a mask, on your own graphics card.
- 3
You get a PNG
Composited against your full-resolution original, transparent or on a colour.
Paid background removers charge per image for this. The model is open, it is 45 MB, and your laptop runs it in about a second. A subscription is often wrapping something the customer's own hardware can now do for free.
Questions
Is my image uploaded anywhere?
No. The image never leaves your browser. There is no server to upload it to — this site is static files.
Is there a watermark or a limit?
Neither. No watermark, no credits, no cap. Drop as many images through it as you like.
Do I keep the full resolution?
Yes. The model looks at a downscaled copy for speed, but the cutout is applied to your original, so the PNG you download is the size you dropped in.
What images work best?
People, products and animals against a reasonably distinct background are close to perfect. Fine hair, glass, smoke and camouflage against a busy background are where it struggles.
Why is it slow in Firefox?
Firefox's WebGPU support is still patchy, so the page falls back to WebAssembly on the CPU. It works, but expect several times the wait. Chrome, Edge and Safari 26+ use the GPU.
A few hundred lines. No backend.
That is what the course teaches — building fast, and getting it in front of people.
