Questions
Is it free?
Yes, free and open source, with no sign-up and no watermark.
Are my photos uploaded?
No. Edge detection, straightening and cleaning all run in your browser.
Does it keep the page shape?
Yes. Paper works out the page's real proportions from the photo and snaps to A4 or Letter when it matches.
