Portable Document Format files (or PDFs) are a type file format that works across all operating systems. It doesn't matter how many times they are transferred or what hardware used. PDF files can contain images, text and links as well as a variety of other data types. They are ideal for sharing documents and storing them on many servers. PDF files can be password protected so that only authorized users can view and make edits. This adds an extra layer of security to existing software. A PDF file can also be used to digitally sign documents. This is a very useful feature. It's now possible to digitally sign documents instead of having to print, sign, and scan to capture a signature.
What is PDF Compression?
Although PDF files are small, they can still be compressed to take up less space. This is great for large files that have to be shared or stored. In the case of videos there is a much greater need to save space using software such as Wondershare UniConverter for videos

Lossless compression is the best method to compress video in order to preserve their structure and quality. This makes sure that the PDF does not lose any information when reduced in size. How can a document shrink with no loss of data? All it takes is managing redundancy. Many files have duplicates of the exact same information. These duplicates can be removed without affecting the original content. Let's say you have a PDF that only contains 3 colors. These colors are composed of thousands of pixels side-by-side to create a solid colored surface. The PDF's original format counts each individual pixel individually. Red pixel 1 through red pixel 2 and red pixel 3 until every one is counted. The PDF compresses these red pixels and treats them as one element, instead of separating them. To make the data a single block, it will code 360 red pixels as "360 red". This is done using run-length encryption (RLE). It takes a string with repeating data and reduces its size by encoding it.
Why bother compressing PDFs?
It sounds great to reduce the PDF's size without affecting the content. But, why bother if the files are small? It would be quicker to keep the files as is. There are many benefits to compressing PDFs. Compression is essential if you and your company value organization as well as efficient ways of handling large amounts of data, for example if you need to send large video files in whatsapp.
These main benefits can be divided into three categories: speed, storage, security.
Transfer speed - Sending and receiving a lot of PDFs in email attachments can cause slowdowns to your servers. Sending smaller files can help reduce heavy traffic. Compression is an easy way to do this. It will take less time to share files and it will allow you to create a zip folder that contains multiple PDFs that can all be sent simultaneously. The recipient only needs to extract the folder and all files will be left in the original format.
Storage efficiency - Let's say you have hundreds or even thousands of PDFs that you want to archive. Although a single PDF doesn't take up much space in the end, they can add up when stored in large quantities. Compression can dramatically reduce the space needed to store all your files. It will take up far less space if you store all your PDFs in one zip folder.
Security - You can add password protection to sensitive documents by compressing a PDF file. Wondershare offers AES encryption. This allows you to set passwords and control who can view and edit the files.
