To reduce a PDF file, you need a PDF compressor software that would decrease its archive disk space by a certain percentage. Often than not, compressor tools reduce PDF files up to 50% of its original size. You may confuse this with Zip files since it is also a compressed format but the main difference with Zip and compressor tools is its format itself. When using a compressor tool, you don’t change the format of your PDF files, in fact, it remains a PDF file no matter its size or transaction.
While Zip files are very useful to users, zip files will only compress the file within its format. Once the file is extracted and decompressed for usage, its original size is restored. The beauty of using a PDF compressor software is that it allows you to reduce pdf file size below 100kb or resize PDF file to 200kb and remain within its file format at the same time. Of course, this would be different on a case to case basis as there are other factors to consider during its process.
Is reducing the size literally mean making it look small?
As funny as that question sounds, this is actually a mind-boggling trivia that will often be found in our heads. How does it really reduce a file without making it physically small? Compressor software and tools work by to remove repeating or redundant data which is then replaced by smaller variables. This doesn’t mean, however, that your data will be changed when you are using it. Each element of the PDF file is audited for space it takes up. Sometimes, when the PDF file contains images, the images are then reduced in size but you don’t have to worry because it doesn’t automatically mean that the quality is also compromised by shrinking it.
