Compress PDF
ExperimentalReduce PDF file size entirely in your browser without uploading to any external server.
Client-Side Compression Note: Web browsers do not have access to heavy server-side engines like Ghostscript. This tool optimizes internal PDF dictionary streams and raster image resolutions client-side. If your PDF contains purely vector text or is already compressed, size reduction may be minimal or negligible.
