Due to technological advances, English as a Foreign Language (EFL) students who previously relied on printed books have switched to digital books. Higher education is, therefore, one of the levels of education currently one of the most heavily touched by digital technologies. This study aims to determine Indonesian students' perceptions regarding using digital books in reading classes. 127 students from a private university in Indonesia took part in this research. This type of research was a mixed-method design that used a five-point Likert Scale survey and semi-structured interviews to improve and support the results of the previous quantitative methods. The conclusion of this study covers students' past experiences, usefulness, preference for digital books vs. printed books, and English learning with digital books. In terms of students’ past experiences, 84% of students have read digital books on computers or tablets, and 92% always use their phones. Moreover, in terms of usefulness, the interviews showed that many participants did not know the highlighting and note-taking features of the digital book. 64% of students prefer digital books, but some interviewees prefer printed books with some justification. In addition, 88% said digital books helped them learn English, especially in reading class, supported by interviews with several participants who said they were better at learning vocabulary from the digital book.
