What happens when you compress a PDF?
Smaller is useful, but the method matters. Understand the tradeoff before replacing your original document.
A PDF is more than a picture
A PDF can hold selectable text, vector shapes, images, links and interactive fields. Different compression methods preserve different parts of that structure.
This compressor renders pages as images
Crucialio’s image-based compression can help scanned documents. It removes selectable text, form behavior and links from the resulting pages. It may make an already efficient PDF larger.
Keep the source and check the output
Compare every page at normal reading size. If text needs to remain searchable or a signature needs to stay valid, retain the original and avoid this compression workflow.
