Converting scanned documents to compressed PDF

Use cases for converting scanned documents to compressed PDF

Scanning has come a long way since the first image scanners were invented in the early 20th century. Today, you can scan documents and images in full color with vivid resolution—but at a cost. Standard 300 dpi color scans create very large files—upwards of 25 MB for an uncompressed, letter-sized TIFF. All of that data chokes networks and email, slows applications, and quickly fills storage archives.

The solution? Use PDF to compress your scanned documents.

Compression reduces a file’s size, creating a smaller file that’s faster to transmit and smaller to store. PDF files can be fairly compact because they use a very elegant data structure and support efficient compression algorithms.

Compression technology is a veritable alphabet soup of options, with names such as CCITT, G3/G4, JPEG, JPEG2000, JBIG2, MRC, and ZIP. But you don’t need a college degree in compression to get good results. You can get higher compression and quality by using better software. Better solutions create color scans that are only about 40-80 KB per page. That’s very small—in fact, it’s about the size of a typical black and white TIFF.

Use OCR to create searchable PDF documents

In addition to reducing file size, converting scanned documents into PDF gives you another major benefit: searchable text. Searchable PDF files are similar to normal PDF files, except that they include an invisible overlay of searchable text. This turns your scanned document into a source of intelligence, enabling you to use your digital file system as a searchable database to help locate the information you need.

Archive smaller PDF files for the long run using PDF/A

An ISO-standardized version of PDF, PDF/A ensures that documents you archive will keep their appearance and readability over time. You get more predictable, consistent results from PDF/A, which is useful if you’re expecting those documents to be accessed far into the future.

How PDF optimization benefits business

A growing number of enterprises have digital mailrooms that scan and email all incoming paper documents. They also have digitization projects requiring paper documents, such as contracts, insurance forms, and customer records, to be digitized into their document management system. Both of these are areas where color scanning, OCR, and PDF/A are useful features for PDF optimization.
