Common questions

Which PDFs does this work best for?

Scanned documents, where each page is already an image. Text-based PDFs may get larger and lose selectable text.

Will the text still be selectable?

No. Pages become images, so check that the result is still easy to read.

What if the output is not smaller?

Try the Standard quality level, or keep your original file.
