Remove an image background in the browser
You do not have to upload a portrait to punch out the background. On-device models are good enough for many product shots. They are not studio retouching.
Background removal is a matte: for every pixel, how much of the subject is here? Cloud tools like remove.bg run large models on their GPUs and usually win on hair, veils, and bicycle spokes. StackImage runs BiRefNet-lite 512 in the page. The first visit downloads weights from our storage. The photo itself stays in memory.
A honest quality bar
- Clean product on a desk, person on a plain wall: usually usable.
- Flyaway hair, wine glasses, bike wheels, fog: expect holes or halos.
- We output a transparent PNG (or a flattened color if you pick one). We do not offer a paid “HD” matte.
- Images above 16 megapixels are rejected. Crop or resize first.
- Open Remove Background and drop the photo.
- Wait for the model (first time) and the matte.
- Inspect edges at 100 percent. Download if it is good enough.
- Compress or convert if you need a smaller PNG or a JPG on a solid color.
Remove the background privately
On-device subject matte. No remove.bg account.
When to pay remove.bg instead
Pay the cloud tool when the cutout is the product (a catalog, a headshot for print) and you accept that the pixels leave the machine. Stay in the browser when the photo is personal, or “good enough for a slide” is the bar.
