About Compress app
Users often need to compress PDF documents to make them smaller and more manageable. Smaller files upload and download faster, saving time and bandwidth. They also use less storage space, which is crucial. Compressed PDFs are easier to email, especially when dealing with attachment size limits. They also enhance website performance, print more efficiently, and cut data transfer costs.
Different applications can compress PDF documents, but they are often non-free software that takes up space. You would not want to install a massive, paid program just to shrink PDFs. Also, many of them do not have mobile versions, and finding a computer with the right software can be time-consuming and uncertain.
