Tips for Compressing PDF below 100 KB

Compressing your PDF files is advantageous to you in numerous ways, including the following:

  • They tend to take up less disk space than non-compressed files.
  • They are also easier to transfer and transfer faster.
  • They tend to be easier to manage.

But most people don't realize that there are certain disadvantages that can come with compressing files. These include the following:

  • When uncompressing the file for reading on your computer, the computer may end up using more memory to complete the task. This could affect the overall performance of the computer since it will have to allocate free memory to the task of uncompressing the file.
  • Uncompressing the file will also take a lot of processor time. This is because the process itself is very slow, and it can take quite a while to decompress a file.
  • Of course, uncompressing the file will significantly increase the size of the file. This is a problem when the compressed file contains a collection of very large files.
  • Since we tend to receive compressed files, there are often sources of viruses and malware that can infect the computer. It is, therefore, very important to scan compressed files that you receive for these viruses and threats before uncompressing them.
