PDF reader apps provide a way to access and read PDF files directly on a phone or tablet. These apps typically include tools for zooming, scrolling, and moving between pages while keeping text and formatting consistent.
Navigation and readability features can vary between apps. Many include page thumbnails, bookmarks, and search tools to help users find specific sections quickly.
File handling is another area where PDF reader apps differ. Some focus on simple viewing, while others include organization tools such as recent files, folders, and file lists.
Additional features may include text selection, copying, and support for links embedded in PDFs. Some apps also provide options for annotations, highlighting, or signing documents.
