How to use this tool

Try the lossless option first. If it does not reduce the file enough, try another available setting and inspect small text, images and diagrams at a useful zoom level.

What to check

Compression savings depend on the source. Image-based rebuilding can alter text selection, links or document features. Verify the output rather than assuming the smallest file is suitable.

Why did compression make little difference?

The original may already be efficiently compressed. A stronger setting can trade quality or document features for size, so compare the actual output.
