The PDF editor provides a complete annotation toolkit accessible from the toolbar at the top of the viewer. Text annotations support free-form typing anywhere on the page.
Highlight tools include standard highlight, underline, strikethrough, and squiggly underline. Each annotation type supports custom colors.
Shape tools provide rectangles, circles, lines, arrows, and polygons. All shapes support fill color, border color, border width, and opacity settings.
Digital signatures can be created by drawing, typing, or uploading an image. The signature is stored locally for reuse across sessions.
Form filling detects interactive form fields automatically and provides type-appropriate input widgets.
