Create PDF from Scanner

Nitro Pro provides you with an easy way to convert your paper documents to digital form for easier storage and access. Depending on the type of scanner you have, you will be able to convert individual pages or entire documents in one process. If required, you can also merge different documents to create a PDF document compiled from various paper sources.

To scan paper documents to PDF:

  1. On the Home tab, in the Create group, click the PDF button, then hover your mouse over From Scannerto access the sub-menu

  2. Click Single Scan, and in the Single Scan Settings dialog select your scanner, the sheets to scan, image compression, and then specify the destination

  3. Click Scan to open your default scanning software

  4. Select the scanning mode - color, grayscale, or monochrome/black-and-white

  5. Select the menu command to return to Nitro Pro

  6. Select the Finish option to end your scanning job, or select the Scan front of sheet two to continue scanning

NOTE: If the document was skewed during scanning, please see the Change the page view section of this guide.

For information on how to rotate one or more pages in the document, see Rotate pages.

Image compression settings

When scanning to PDF with Nitro Pro, the type of compression used-color, grayscale, or monochrome-is determined by the output setting you select in your default scanning software. Therefore, if you intend to do a color scan, you do not need to modify the monochrome settings as they will not affect your image.

  1. Color/Grayscale

    • JPEG: The main Joint Photographic Experts Group standard achieves 10:1 compression ratios with little perceptible quality loss

    • JPEG2000: Achieves higher compression ratios than JPEG, and uses both lossy and lossless compression in the same file stream

    • ZIP: Uses the ZIP compression algorithm to reduce the image size without affecting quality

  2. Monochrome

    • CCITT Group 4: A fax document transmission standard which uses advanced compression methods for lossless reproduction

    • CCITT Group 3: The Group 3 standard achieves less compression, and is less advanced than the CCITT Group 4 method

    • Run Length: Particularly effective on files that contain many long runs of the same bit, value, or character. This method is primarily used on binary files

    • ZIP: Uses the ZIP compression algorithm to reduce the image size without affecting quality

  3. Quality

    • 72DPI: Might be suitable for use on the web due to the smaller file size produced, however will not produce high quality prints

    • 96DPI: Slight quality improvement over 72DPI, but will still not produce high quality prints.

    • 120DPI: Improvement in viewing and print quality over 96DPI, but still below standard levels
    • 150DPI: Suitable for higher quality viewing on computer monitors

    • 300DPI: The standard generally used for office quality prints, and generates slightly larger file sizes
    • 360DPI: Slight quality improvement over the standard 300DPI setting

    • 600DPI: Generates larger file sizes, however it is recommended for high print quality of the image

    • 1200DPI: Will generate the largest file sizes - recommended when image and print quality is of the highest priority

Optical Character Recognition (OCR)

  • Make document searchable: Use OCR to create an invisible layer of active text that can be searched and annotated above the image-based PDF file

Additional Options

  • PDF/A-1b compliance: Create an archival-grade PDF file that complies with the PDF/A-1b standard

  • Open the PDF file after creation: Open the newly created PDF file in Nitro Pro after creation
