Strips metadata and re-packs the file structure to shrink size

Note: this tool performs lossless, metadata-based compression entirely in your browser. Because true image re-compression requires a server or heavy WASM codec, savings are typically modest (often 5–20%) and depend on how the PDF was originally generated. For PDFs dominated by large embedded images, re-export the source document at a lower image quality before compressing here for best results.
