Compress PDF

Your PDF files are processed entirely in your browser and are never uploaded to any server.

Browser-only optimization is limited. This performs a safe, lossless re-save (no quality loss, no page rasterization) and may not reduce every PDF — especially files that are already optimized. Image-based compression is not available in the browser and is planned as future work.
