Why Use Our Free Online PDF Compressor?
100% Secure & Client-Side
Unlike other PDF compressors that upload your sensitive documents to a remote server, our PDF Compressor utilizes advanced WebAssembly and Native JS to process your documents directly inside your browser. Your files never leave your device, ensuring maximum privacy and zero reliance on server capacity.
High Quality Rasterization
By dynamically adjusting the DPI and JPEG compression ratio, our tool significantly reduces the file size of scanned documents, heavy portfolios, and image-rich PDFs without completely destroying the text readability. You control the exact balance using our easy compression slider.
