Frequently asked questions

Will the text stay searchable?

Preserve text keeps the existing text. Image mode rasterizes every page and removes searchable and selectable text. It is intended mainly for scanned PDFs.

Why is my PDF not smaller?

Some PDFs already use efficient compression. If a candidate is not smaller, the tool keeps the original bytes and reports zero savings.
