FAQs About PDF.Live’s PDF Compression App

What does it mean to compress a PDF document?

Compressing files refers to condensing a big PDF into a small PDF so it's easier to send for things like email, text, and other online file sharing platforms. For example, if you need to upload a resume for a job application, the hiring company might limit the size of the PDF that you can upload. Compressing a PDF removes certain elements or reduces the file size without quality loss. Technically speaking, the compression process looks for redundant elements in files and gets rid of them, while retaining the quality of the file. The compression process produces a compact PDF.

Is PDF file compression the same as zipping files?

Short answer is, no, compression and zipping files are not the same. Compressing files reduces the size of individual files by permanently changing certain features such as images, graphics and colors on the PDF. Zipping files retains the original elements and temporarily “squishes” them into a smaller, more sharable .zip format. When you double click the zip file, that returns it to its original formats. You cannot compress multiple PDFs into one file; however you can merge them. And you can zip multiple file types together. Make sense? Read more on how to zip files.
