All compression stays in your browser. Lossless preserves document structure; Balanced and Strong deliberately flatten pages for much larger reductions on scanned or image-heavy PDFs.

Extract, reorder, delete or rotate pages in {workingPdf.file.name}. Enter pages such as 1-3,5,8-6. Descending ranges reverse page order.
PDF operations rewrite document structure. Existing digital signatures can become invalid, and unusual/encrypted PDFs may not be supported. This tool does not claim secure redaction or PDF compression.

PDF operations rewrite document structure. Existing digital signatures can become invalid, and unusual/encrypted PDFs may not be supported. Lossless compression mainly optimizes PDF structure and streams, so an already-efficient or image-heavy PDF may shrink only a little. Balanced/Strong modes flatten every page into a JPEG-backed page, so text selection, links, forms, bookmarks, accessibility structure and digital signatures are not preserved.
