Overview
Open a PDF, move through its pages, and add text notes, images, outlined boxes, colour highlights and freehand pen marks anywhere. Select mode lets you drag things around or delete them, with undo/redo. When you download, every edit is written into the PDF itself with pdf-lib — it's not a viewer-only overlay. Text uses a standard sans-serif font; whole-page reordering isn't in this version (use Organize PDF to reorder or delete pages).
