AlifBay Scan To PdfScan any document to an A4 PDF at its actual size
Most scanner apps stretch everything to fill the page. When you need a true-size copy of a certificate, a photo or a small document, put it on a white A4 sheet and let the sheet be the ruler.

How it works
- Put the document on a plain white A4 sheet, on a darker table.
- Open the scanner in A4 sheet mode and fit the sheet in the frame. Keep the phone flat above it.
- The app finds the sheet's corners, straightens the photo and, because A4 is exactly 210 × 297 mm, knows how big your document really is. The adjust screen shows the size it found.
- Your document is cut out and centred on a clean A4 page. Save, share or print.
Documents bigger than the sheet, like a full A4 letter, still scan fine: the result is the sheet itself, straightened and cleaned like a scanner would do it.
Good for
- Mark sheets and certificates you need to print at original size
- Passport-size photos, cheques, receipts and small slips
- Combining two small items on one page (front and back, or two documents)
Questions
Why do I need a white A4 sheet?
A phone photo has no sense of scale. A4 is always 210 × 297 mm, so the sheet tells the app how big your document really is.
Will it remove shadows?
Yes. "Clean white paper" evens out lighting and makes the background white, like a scanner.
Is the PDF A4?
Yes. Every page is A4 at 200 dpi, with your document at real size and centred.
