Turn paper photos into a document you can check.

Make the paper edges the page edges

Photograph the whole sheet against a contrasting background. Check all four suggested corners and move any that fall inside the text or outside the paper. A correct crop removes the table around the page without cutting off a line.

Keep faint marks readable

Compare the original with the cleaned preview, especially light pencil notes, stamps and fine lines. If black-and-white cleanup loses detail, use a gentler or colour treatment. Retake a blurred photo instead of expecting a stronger filter to repair it.

Balance the size limit with legibility

Enter the portal’s real byte limit and create the PDF. Read the achieved size and status before downloading. If the target is missed or fine text becomes unreadable, change the permitted settings or retake the source; a small unreadable file is not a useful result.

Check the downloaded copy

• Reopen the PDF and check page count, order, corners and the smallest text.
• Check the actual byte size. The PDF holds pictures of the pages, not text you can search or copy.
• Keep the original files until you have checked the downloaded copy.
