High Compression PDF Conversion - (Image2PDF)
|
VeryPDF Image2PDF OCR Product has
high compression PDF conversion function to compress the size of full-color
document files, which contain large volumes of data, down to a size at which
they can be easily handled over networks.
Our high-compression PDF conversion technology, which maintains the text quality
of color documents in compressed files the size of those for monochrome
documents, was made possible by image analysis and compression technologies
based on our innovative document analysis technology. With conventional JPEG
compression, an A4-size color document filled with text and photos, scanned at
150-dpi resolution, would create a file around 2MB in size. However, using our
high-compression PDF conversion technology, the file is compressed to about
one-tenth this size without compromising image quality.
To achieve this, scanned images are first converted into multiple layers for
elements such as text, backgrounds and other graphics. Optimized compression
methods are used for each layer, and the multilayer function of the PDF format
is then used to re-integrate the layers. With conventional PDF compression,
reduction of overall resolution usually means visual deterioration of the text
component. Using VeryPDF Company's advanced document analysis technology,
however, the files size of the overall document can be reduced without lowering
the quality of the text portion and its color. The text quality is high enough
to allow easy adding of character codes using optical character recognition
(OCR). This technology is ideal for use in offices, where the text portions of
documents are most important.
