White background maker

Padding to white does two things at once: it makes your photo square, and it fills the empty space around your product with pure white. If your product was photographed on a white sweep, a lightbox, or a sheet of white paper, the whole frame ends up white and your product sits cleanly in the middle.

SelfShot uses exact white, red 255, green 255, blue 255, for the padding. That is the value Amazon's public photo guide describes for a white background. After it builds the image, it checks the border of your product area and confirms whether the white is truly pure, so you are not guessing. A passing check is not Amazon's approval.

Yes, the padding SelfShot adds is exactly 255, 255, 255, and the pure-white check confirms the result. The one condition is that your product itself must be on white in the original photo. If the area immediately around your product is a light gray studio backdrop, that gray will show, and the check will warn you with the exact value it found.

That warning is the useful part. Instead of uploading and getting rejected, you learn before you list that the background needs another look, and you can adjust your lighting or backdrop and try again.

Padding cannot remove a busy or colored background. If your product sits on a wooden table or a patterned cloth, padding will square the photo and add a white border, but the table or cloth will still be there behind the product. For those shots you need a real cutout.

Automatic subject cutout is not part of this version, by design, because the strongest browser library for it is licensed in a way that is not safe to resell. If you need a cutout, use a dedicated tool first, then bring the result here to size it and confirm the white is correct.
