About Sign PDF

Upload any PDF and add your signature using three methods: draw freehand with mouse or touch, type your name in a handwritten font, or upload an existing signature image (PNG, JPG). Each signature can be dragged to any position on any page, resized, rotated, and adjusted for opacity. Place multiple signatures across different pages in one session. All processing is handled entirely in your browser by pdfjs-dist and pdf-lib — no files are uploaded to any server.
