Fill & Sign PDF

Fill & Sign lets you complete a PDF the way you'd fill in a paper form: click anywhere on the page and add exactly what you need. Drop in text boxes and type, place a checkmark in a tick box, stamp today's date, or draw freehand with your mouse, finger, or stylus to add your initials or a signature. Because everything is placed freely rather than into predefined fields, it works on any PDF — a flat export, a scanned or printed form, or an interactive one — not just documents that were built to be fillable.

Each text box has its own font (Helvetica, Times, or Courier), size, and color, and characters outside those fonts — Cyrillic, Greek, Vietnamese, and other extended-Latin — are drawn with an embedded Noto Sans so they still render in every viewer. The whole editor runs in your browser with pdf.js and pdf-lib, so your document is never uploaded and never leaves your device. If you only need to fill a PDF's existing interactive fields, use Fill PDF Forms; for a dedicated, reusable signature, use Sign PDF.
