PDF optimizer
Rewrite and compact a PDF locally
PDF optimization rewrites the document structure and may reduce its size. It cannot guarantee a smaller file, especially when the PDF is already optimized or contains compressed scans.
Image conversion uses your browser's canvas. PDF processing requires loading the PDF library from jsDelivr; if it is unavailable, PDF optimization is disabled. Processing takes place locally after the library loads.
