Place each corner on the paper edge in clockwise order: top-left, top-right, bottom-right, bottom-left. Detection works best on bright paper against a darker surface.
Good questions. Simple answers.
What if automatic detection fails?
The full image remains selected and you can set all corners manually. The tool reports low confidence rather than claiming success.
Is this OCR?
No. The result is an enhanced image, including when saved as a PDF. It does not recognize text.
Are my files uploaded?
No. These tools process files on your device. Download your result before leaving the page; a reset clears the current workspace.
