Instead of zooming in and out or dragging the page left and right, you can read documents in a natural vertical flow that fits your screen width. It’s especially helpful for: - research papers - reports - manuals - articles - Word documents - PDFs with figures, colors, and formulas PDF Reflow keeps the look and structure of your document while making it much easier to read on a small screen. You can also: - select and highlight text - search inside documents - adjust text size up to 300% - show the PDF in dark mode - pick a PDF inside the app If you read PDFs on your phone and hate fighting the layout, PDF Reflow is built for that problem.
