Why Use PDF Compressor
PDF files — especially those with embedded images — can be very large, making them difficult to email or upload to online forms. This tool reduces PDF file size by optimizing the internal structure without altering the visible content. Text remains sharp, layouts stay intact, and the document remains fully readable at a smaller file size.
