Why PageInk

Focused on one job — add and adjust text on PDFs — without uploading files to someone else’s server.

  • Nothing uploads

    Your PDF stays on your device. All rendering and export run in the browser.

  • Click to add text

    Place text anywhere on the page — labels, names, dates, notes, or corrections.

  • Edit existing text

    On text-layer PDFs, update what’s already there with whiteout and redraw.

  • Fonts & colors

    Helvetica, Times, or Courier — size, bold, and color you control.

  • Undo & redo

    Fix mistakes fast with keyboard shortcuts and a full history stack.

  • Multi-page

    Navigate long documents and add text on any page before you download.
