How it helps

Use the black-and-white document scanner effect for mobile photos of marksheets, caste certificates, handwriting samples and signatures taken in uneven light. Choose a cleanup strength and save a smaller JPG, sharp PNG or A4 PDF locally.

Questions
Common questions about this tool
Can this remove dark shadows from a marksheet photo?
It can brighten paper tones and increase contrast. Very deep shadows or blurred text may still require a new photograph.
What is the best mode for a text certificate?
Black & white gives the cleanest scanner look for plain text. Use grayscale or colour when stamps, photographs or coloured marks matter.
Can I save the scan as PDF?
Yes. PDF output places the cleaned image on one A4 page.
