Fonctionnement
How does this tool work?
Lossless mode rewrites and optimizes the internal PDF structure without rasterizing pages. Balanced and strong modes render every page locally and rebuild the PDF from JPEG images to achieve greater size reduction, at the cost of selectable text and some interactive elements. No file is uploaded and the transformation is available in Workspace.
