Tired of oversized PDFs filled with high-resolution images that slow down sharing, email sending, and uploading? Most standard PDF compressors only reduce file size blindly, blurring pictures, ruining graphics, and destroying document quality. If you want to compress PDFs smartly while keeping clear visuals, you need a professional tool with dedicated image optimization features — and PuraPDF delivers it completely free online.
