Open a book

A PDF or an EPUB, read in this tab; the file is never copied into browser storage.

Drop a PDF or an EPUB here, or

The shelf

Everything you have opened, with where you stopped; the book is opened again from where you keep it.

Bookmarks and highlights

Select text in the book to highlight it in one of four colours; each mark takes a note.

How it works

READER works on a phone as well as a computer. Nobody receives a copy of the book or a record of what you read, because the file is never uploaded.

The guide: A free PDF editor that never uploads your file

Doing this often? PDF Studio annotates, compares and searches PDFs, and makes scanned pages searchable with OCR. On its own, US$4 a month; with everything else, US$9 a month or US$79 a year. 7 days free.
