JPEG2000 Compress PDF.

Compression may reduce image detail or remove unused data depending on the profile. Review the output before replacing the original PDF.

SnapPDF does not guarantee a fixed compression ratio. The final size depends on images, fonts, structure, and whether the PDF was already optimised.

Image handling depends on the compression profile. SnapPDF may recompress, resize, or leave images unchanged to preserve readability.

Metadata preservation depends on the compression path. Check the downloaded PDF if document properties or embedded metadata matter.

Yes, but a PDF that is already optimised may shrink little or not at all. Recompression can also reduce visual quality.
