What Is PDF Compression?
PDF compression reduces the file size of a PDF document by stripping unnecessary metadata, optimizing images, removing redundant data streams, and rebuilding the internal structure more efficiently. This makes large PDFs easier to email, upload, and store without significantly affecting visual quality. Our Compress PDF tool performs all optimization locally in your browser.
