Compression level

The tool redraws each page locally and rebuilds a smaller PDF, so it works best for scanned PDFs, image-heavy files, and PDFs you need to email or upload.

If compression does not make the file smaller, the tool keeps the original PDF. Scanned PDFs usually shrink more than text-first PDFs.
