PDF Compressor
PDF Compressor reduces the size of your PDF files entirely in your browser using pdf-lib. Choose low, medium, or high compression and compare the before and after sizes of each file. Reduction is real but varies by content: text- and vector-heavy files shrink far less than image-rich documents.
