Scanning files nowadays has gained a lot of importance in many ways. By scanning files one can preserve important documents on the hard disk which in turn assures no loss of data. One can scan documents and send it over through email to another person located remotely. A scanned file is produced in many formats like TIFF, JPEG, PNG etc. But often due to space complexity and for sharing issues it is required to compress scanned files. Hence we come to the point on how to compress scanned files using the two basic methods Lossy compressions and lossless compressions.
Lossy Compressions to Compress Scanned Files:
If you are willing to compromise on the quality to compress scanned files, lossy compressions is a better option for you. For lossy compressions the font used in the files are unified into one single font. Any pictures or videos in the files are compressed as well into an inferior quality. JPEG is a common format that is produced when Lossy method is used to compress scanned files. For JPEG format the size of the files become 1% of the original files. The quality once degraded by compression cannot be recovered. Hence one should opt for Lossless compressions if the quality is to be retained.
Lossless Compressions to Compress Scanned Files:
For lossless compressions, the image quality and the appearance of the file remains the same after compression. Here the size is not reduced by as much as that of lossy. To compress scanned files Lossless compression techniques often use WinRAR and WinZip to compress the files. CCIT is the format in use for monochromatic 1 bit depth files transferred over fax or mails. The JBIG2 format gives 7 times more compressed files than the CCIT format. Hence keeping in mind the parameter of higher importance, i.e. quality or size on should zero in on the technique to compress scanned files.
