What is a PDF Compressor?
A PDF compressor is a utility that reduces the file size of a PDF document by optimizing images, removing redundant data, and simplifying internal structures. The goal is to make the file smaller while keeping the text and visuals clear and readable. Our online tool lets you choose a compression level to balance quality and size.
