Credits are only for Pixelize. They keep a simple rule on purpose.

The basic rule
1 credit = 1 Pixelize image. If you generate four images in one run, that costs four credits. The Generate button shows the total before you confirm.
Free tools never spend credits
Remove Background and Fix Pixel Grid run locally and cost 0 credits, signed in or not.
Failures
If a Pixelize generation fails, AniPixel refunds the credit for that failure. You’re not paying for empty results.
Where credits come from
