About This Tool
Adding a signature to a PDF is one of the most common tasks in everyday document workflows. Whether you need to sign pdf contracts, authorize invoices, or approve internal memos, this free online tool lets you place your signature on any page of a PDF in seconds. You can draw your signature using a mouse or touchscreen for an authentic handwritten look, or type your name and choose from several elegant cursive-style fonts for a clean, professional result. Either way, the signature is embedded directly into the PDF so the document looks polished and ready to share.
This sign pdf tool runs entirely in your browser using client-side JavaScript and the pdf-lib library. Your files are never uploaded to a remote server — they stay on your device from start to finish. That means sensitive contracts, financial documents, and personal paperwork remain completely private. There are no file-size restrictions beyond what your browser can handle, no daily usage limits, and no watermarks stamped onto your output. Simply upload your PDF, create your signature, pick a position on the page, and download the signed document. It works on any modern browser across desktop and mobile devices with no software installation or account creation required.
