Make phone photos look like real scans
When you photograph a document with your phone, the paper often looks gray or shadowed. This filter whitens the background and darkens the text so the document looks like it went through a scanner.
Choose between a balanced mode, high-contrast black and white, or clean grayscale.

Frequently asked questions
I have JPG photos, not a PDF. What do I do?
Convert them first with JPG to PDF, then apply this filter.
Which mode should I choose?
Balanced works for most documents. High contrast is ideal for printed text. Grayscale preserves faint stamps and signatures.
Does the result keep selectable text?
No. The result is one image per page, just like a scan. Use OCR afterwards to make it searchable.
