About this tool

A phone photo of a page is usually skewed, shadowed and grey. Add it here and the four corners of the paper are found automatically; if they are not right, drag them with your finger or mouse. The page is then straightened, the paper turns white and the writing dark. Choose colour, grey or black-and-white (like a photocopy). Add many pages and save them as one PDF, in A4 or at the picture's size. It works for NID cards, certificates, receipts and book pages. Your pictures stay on your device.

When to use it

Photograph a paper page with your phone and get a clean scan as a PDF or JPG: straightened, cleaned and with better contrast.

Tips

Put the page on a dark flat surface, use good light and avoid shadows. Hold the phone parallel to the page. Use several photos and merge them into one PDF.
