Folio PDF vs. Adobe Acrobat Reader
Folio PDF is about 4 MB, free, with no account, no ads and no Internet permission, and it does the everyday job: opening, reading, searching and copying text from PDFs. Acrobat Reader is a full suite with editing, signing, OCR and cloud sync, plus ads, in-app purchases and an Adobe account for premium features.

Common questions.
Does Folio PDF replace Acrobat Reader for reading?

Why is Folio PDF only about 4 MB?
Because it does one job: opening, reading, searching and copying. It leaves out editing, conversion, cloud sync and OCR, which a PDF suite carries.
