Digital Signature Tool
Free digital signature tool — draw, type, or upload a signature and embed it directly into a PDF. Your file never leaves your browser. Download signed PDF instantly.
This free digital signature tool lets you add your signature to any PDF directly in your browser — by drawing it with your mouse or touchscreen, typing it in a script font, or uploading an image of your handwritten signature. Position it anywhere on the page, resize it, and download the signed PDF instantly. Your file never leaves your browser.
Drawing, typing, or uploading a signature and embedding it into a PDF is not the same as a legally binding electronic signature (e-signature) under laws like ESIGN or eIDAS — but for most everyday purposes like signing freelance contracts, internal approvals, and simple agreements, it produces a PDF that looks signed and is widely accepted.
Upload your PDF, choose the page where the signature should appear, draw or type your signature, drag it to the correct position and resize it, then download the signed document. The signature is embedded as an image in the PDF at the position you set — it is visible when the PDF is opened in any viewer.
The tool handles multi-page PDFs — you can navigate between pages and place signatures on multiple pages if needed. If you are signing a contract that requires initials on every page plus a full signature on the last page, you can do that in a single session.
For documents that require legally binding e-signatures with audit trails, identity verification, or certificate-based signatures, use a dedicated e-signature platform. For everyday signing of straightforward agreements, this free tool handles the task in seconds without creating an account.
