How to Use the Bulk Background Changer

1. Drop the batch

Add as many images as your browser handles — no fixed batch cap in the tool. Best results come from contrasting, evenly lit backdrops.

2. Tune tolerance

Pick transparent or a replacement color, then set sampling tolerance low and raise until backgrounds drop cleanly.

3. Download ZIP

Save all processed images at once. One batch save counts as one Pro download (signed-in free: 2 a day).

Frequently Asked Questions

How many photos fit in one background batch?

No fixed batch size — add as many as your browser handles; a 40-photo supplier set runs fine on desktop. Process the trickiest 10 first to dial in tolerance. Only the final ZIP save counts as one Pro download.

How do I avoid halos around hair and edges?

Shoot on contrasting, evenly lit backdrops and set tolerance low first — raise it only until the background drops. Check results at 200% zoom: a 30-second edge inspection beats re-running 40 files. Glass, smoke, and backlit hair always need a manual finish.

Are my batch photos uploaded anywhere?

No — detection and compositing run locally in your browser on Canvas, so images never leave your device. Only the final ZIP save counts as one Pro download; processing itself is uncapped and private.

Transparent or solid replacement — which sells better?

Pure white (#FFFFFF) for Amazon, Flipkart, and Meesho listings that require it; transparent PNG for design overlays and logos. Export JPG for smallest listing files, PNG wherever transparency matters.
