Jo's PDF Text Viewer

Read PDFs and text files in a clean local reader with bookmarks, reading progress, and adjustable text settings.

JS PDF Viewer is a simple local reader for PDFs and text files.

Import PDF documents from the Files app, keep them organized in your library, and continue reading from where you left off. You can save bookmarks, return to important pages, and manage your imported documents directly on your device.

The app also includes a text reader designed for comfortable long-form reading. Open sample text or import plain text files, then adjust font size, line spacing, and margins. Text is divided into pages based on your current reading settings, making it easier to read longer documents without continuous scrolling.
