Alternative
A free alternative to BgSub background removal
BgSub is interesting because it runs the segmentation model on your device using WebAssembly. That means no upload, which is a real privacy benefit for sensitive images. The catch: on older phones and low-end laptops, it is slow, and the model quality is lower than what a server can run.

- —BgSub runs the model on your device, so performance depends on your hardware.
- —The model is optimized for size, which means lower quality on difficult edges.
- —The initial model download is a few hundred megabytes and only happens once per browser.
- —Remova gives you both: server processing for quality, browser-only for privacy.
Choosing between local and server processing
- 01For most images, use Remova's automatic mode. The server has a better model and finishes in twenty seconds.
- 02For sensitive images (medical, legal, private), use Remova's manual mode. It runs entirely in the browser with no upload.
- 03Both modes produce PNGs with alpha at the source resolution.
The trade-off is: local processing for privacy, server processing for quality and speed. Remova lets you pick per image.

Common questions
Does BgSub upload my images?
No. Everything runs locally in the browser. That is the whole point of BgSub.
Does Remova upload my images?
In automatic mode, yes. In manual mode, no. You choose which to use.
Which is better for privacy?
BgSub is strictly better for privacy because it never uploads. Remova is better for quality and speed. Neither stores the file after processing in automatic mode.
