The TIFF Saga
TIFF or Tagged Image File Format is a popular image format used for scanning, faxing, word processing, and Optical Character Recognition. This helps in digital archival of records using TIFF images. TIFF files have advanced pixel data types and are hence used in scientific imaging where precision is essential. TIFF as an image file format was a contender for the de facto standard for digital documentation and archival. However, it lost to PDF, not as much due to variations in features, but primarily due to the fact that PDF file format entered the public domain. PDF files have the advantage of portability, hence requiring conversion of formats like TIFF itself to PDF for global distribution.
TIFF to PDF Compression
Conversion of TIFF files to PDFs, and compression of the PDFs for storage can be done easily using software. TIFF file conversion and compression software are available over the Internet for download. It can also be done using any of the few online services that have started offering the same. However, the online services provide only basic functionality as compared to the TIFF file conversion software for offline usage. If the requirement for precision arises, SDKs can be used to embed the conversion functionality into your own piece of code. Technically, the TIFF file format is made up of images as well as data. The images can be raster or vector, colored or monochrome, and are compressed using various algorithms like JPEG and LZW.
TIFF files can be converted to PDF using the conversion software. The software can then apply compression to the PDF to obtain a decent storage size. Some software allow single as well as batch compression of TIFF files to PDF. Various PDF compression algorithms such as JPEG2000 Lossless and Lossy, JBIG2, CCITT G4 and G3 and ZIP are supported. Multiple TIFF files can be compressed into a single page PDF. Multi-page TIFF files can also be compressed to a single PDF. Automatic image pre-processing is supported by some file compression software. PDF security restrictions can be set during the TIFF compression process. And the best feature for geeks who need to process volumes of TIFFs is the command-line.
