About this tool
After photographing paper, place each corner on the actual document edge. Choose an enhancement that keeps text and stamps readable, then arrange multiple pages before combining them into a PDF.
How to use
Document photo scanner
Turn phone photos into a scanned PDF. Arrange the pages and place all four corners on the paper edges. Use colour for stamps, or black-and-white for clear print; check that faint writing survives enhancement. The preset enables A4 and a combined PDF while keeping corrected page images. For further layout changes, send selected results to Images to PDF without selecting the originals again.
What this tool is for
Detect and refine page corners, correct perspective, apply colour, greyscale, or black-and-white enhancement, and optionally combine pages into a PDF.
How to use it
Let the tool suggest document corners, drag each point to the true paper edge, and choose colour enhancement, greyscale, or black-and-white output. Download corrected pages individually or combine them into a PDF in queue order.
Results and next steps
Every page produces a perspective-corrected image; enabling Combine also creates a PDF in the current queue order.

Common questions
What if the suggested corners do not follow the paper?
Suggestions can be inaccurate with low contrast or a complex background. Drag each point to the actual corner, then inspect the corrected text and edges. Export page images or a queue-ordered PDF; the PDF has no OCR text layer.
Why are my four corners still reported as invalid?
They must form a complete convex quadrilateral, without crossed edges, coincident points or an inward fold. Move each point to its corresponding paper corner rather than the opposite corner, then inspect the corrected preview before exporting.
Which scan mode suits contracts, receipts and stamped documents?
Use colour when stamps, annotations or photographs must retain their colour. Grayscale keeps tonal detail. Black-and-white applies a threshold, so faint text or pale stamps may disappear; zoom in before accepting that result.
Will a PDF include every source if some pages fail processing?
No. It includes only successfully corrected images, not failed originals. Check page count and order, resolve the failed pages and regenerate after all required pages succeed to avoid submitting an incomplete document.
