What is PDF Compression?
PDF compression reduces the overall file size of a PDF document by optimizing internal images, removing unnecessary metadata, and compressing structural data without visibly degrading the quality of the file.
A smaller PDF is much easier to share through email (which often has a 25MB attachment limit), upload to web forms, store online, and send through messaging apps where file size limits exist.
