Create the scanned PDF

  1. Arrange every page and side before creating the PDF.
  2. Create a multipage PDF from document photographs without uploading the pages or installing a scanner application.
  3. Flat pages, even lighting, and steady framing improve readability.
  4. OCR is a separate step when the finished scan must be searchable.

Capture readable document pages

Place the document on a contrasting flat surface, avoid strong shadows and glare, and hold the camera directly above the page. Fill the frame without cutting off corners, signatures, stamps, or page numbers.

  1. Clean the camera lens.
  2. Use even light.
  3. Photograph each page steadily and completely.

Arrange the images as one PDF

Open Scan to PDF on a phone or desktop, capture or choose JPG, PNG, HEIC, or HEIF pages, and place them in reading order. Review front and back pages before selecting the PDF layout.

  1. Add every page image.
  2. Correct the sequence.
  3. Choose page settings and create the PDF.

Check the scan and add OCR only when needed

The current scanner does not automatically correct perspective, crop borders, or remove shadows. Review the finished PDF visually. Run OCR afterward only when printed English text must become searchable.

  1. Open the finished PDF.
  2. Inspect readability and orientation.
  3. Use OCR PDF when searchability is required.
