O tomto rozšíření
Ferna PDF Reader opens PDFs in Firefox with every page, portrait or landscape, fitted to the width of the window. It is designed for students, researchers and anyone who reads a lot of PDFs.
NEW IN 1.4
- Smooth, Xodo-style text selection that selects whole words, even in two-column LaTeX papers
- Sinhala support: repairs Sinhala text that other viewers show garbled, for selecting, copying, searching and AI
- Sinhala AI: summaries, questions and quizzes in Sinhala
- Auto-Bookmark: builds a bookmark tree from the table of contents or the headings
- Reference popups with your own default size and zoom (set in Settings), still resizable and zoomable with the mouse
FEATURES
- Zoom (fit width, fit page, percentages) and page rotation from the toolbar or a small menu on the page
- Reference popups: clicking "Figure 3", "Table 2" or an equation number shows it in a floating window instead of jumping away
- Annotations: highlight, underline, strike-out, squiggly, area highlight, pen, marker, text boxes, notes and shapes. The tool panel hides itself as soon as you pick a tool, and a quick popup appears when you select text.
- Stylus like Xodo: a pen writes at any time without choosing the Pen tool, with smooth ink and palm rejection
- AI assistant that runs on your own computer (WebGPU) or on a local server such as Ollama: summaries with page references, questions about the document, study quizzes
- Password protection (AES-256 / AES-128) and standard PDF annotations that open in every PDF reader
PRIVACY
No account, no analytics, no ads, no tracking. Your PDFs never leave your computer.
OPTIONAL FOR WINDOWS
The free Ferna save helper lets Ferna open PDFs from your disk and save straight over them (Ctrl+S) without a Save window. Download: https://tgi25.github.io/ferna-software/ferna-pdf-reader/
