Why is Reducing a PDF File Size Necessary?
Sending a file over an email or uploading it on a file sharing webpage is the quickest way to transmit and receive an urgent file over the internet. But to implement the above file sharing process efficiently, the file to be sent should be of a minimum size for quicker uploading and downloading as well. Most emailing websites have a maximum limit regarding the size of a file that can be uploaded or attached. Hence, the question of how to condense a PDF file has gained immense priority.
Why is a PDF File Size Large?
If a PDF file is generated from scanning a handwritten or printed document, the size depends on the kind of compression algorithm that has been used on the image file. Compression of an image is primarily of two types, lossy and lossless. In lossless compression, for file formats like TIFF, the scanned files are simply converted into images with the quality and content both remaining intact. For lossy compression formats like JPEG, however, the compression algorithm assesses the image and eliminates any unnecessary data present in the image. Hence, the quality of the image may deteriorate in lossy compression but the size is reduced by a large scale. Hence, PDF files generated from Lossless compression are large and require compression.
How to Condense a PDF File?
The use of lossy techniques is one of the primary answers to the question how to condense a PDF file. But in cases where the quality needs to be intact and the file needs to be compressed as well, implementing Optical Character Recognition becomes an efficient solution. OCR can be used to extract characters from an image file and convert them into text characters. One can also optimize the embedded images in a PDF file to condense the final size of the file.
