Conversion & Output Settings

Compression Level

For Word/PowerPoint/Excel files, embedded JPEG and PNG images are recompressed (and downscaled) inside the document.

DOCX/PPTX/XLSX files are ZIP packages: embedded images are recompressed in place (same format, same file names) and the package is rebuilt with maximum compression. Text and formatting are untouched.
Image formats other than JPEG and PNG (e.g. EMF, SVG) are left as they are.
