Reduce PDF File Size

There are several ways to reduce a document's file size to attach in PDF format in CTI Navigator. If you have the original document(s) and a scanner, you can:

1. Re-scan the document at lower resolution. This usually is the quickest and easiest fix. If you scanned the document in color, try scanning in gray scale. If your gray scale scanned file is too large, try scanning as Black and White (1-bit resolution).
2. Re-scan the document in parts (or separate one document into several smaller documents) so that each individual file size is less than 1 MB. For example, Part 1 and Part 2; or Main Document and separate Addenda documents.
3. Scan each page of a multiple page document as an image, save each image as its own file, and then use the Create PDF tool in CTI Navigator Desktop's Document Manager to link these image files together in one PDF document. For instructions on using CTI's create PDF tool, see 'Use Document Manager & Create PDF' on CTI's Help and Tutorials website.

If you cannot reduce the file size sufficiently with a scanner, do not have a scanner, or your original is a text file (such as a Word, PowerPoint or Excel document), you can print the file to a third-party PDF printer utility that will electronically convert its format to PDF. Many popular PDF converters are free to download and use (such as Cute PDF Writer, Bullzip PDF Printer, or PDF Creator), although some may display advertising either in the document or during the creation process.

To convert an existing document (or image) file to a pdf formatted file, you also can use free web-based document conversion services that do not need to be installed on your computer (such as http://convertOnlineFree.com/ , www.freePDFconvert.com, http://docuPub.com/pdfConvert, or www.zamzar.com) .
