When to use this tool
For a photo-scan PDF, choose quality and the maximum long edge of embedded images. It recompresses supported JPEGs rather than turning every page into an image.
File workflow example
This illustrates the expected operation. Actual file size, quality and recognition depend on your source and settings; inspect the result in the tool.

Example result

How to read and check the result
Read optimized-image counts alongside saved bytes. Already optimized files or PDFs without supported JPEGs may not shrink; if the result grows, the original is returned. No fixed compression ratio is promised.
