Compress PDF questions

Why can compression remove searchable text?

Strong compression flattens each page into an optimised image. Links, forms, layers and digital signatures may also be removed.

What if the PDF cannot be made smaller?

Paperuna returns the original document rather than reducing quality without producing a smaller file.
