Frequently Asked Questions

What does the Crimson Background Tool do?

It’s perfect for portraits, profile pictures, product photos, or any visuals that need a dramatic and polished look. Just upload your image, and the transformation is done in seconds, completely free.

Does the tool remove the existing background before applying crimson?
