Common questions
What image types work for background overlays?
PNG and JPEG images are supported in this first pass. The tool loads the image locally and previews its placement before export.
Can Pdf Clarity avoid overlapping important page content automatically?
No. The tool previews placement and warns about higher-risk combinations, but it does not inspect or reflow existing page content automatically.
