How to sign a PDF without uploading it

You can sign a PDF without uploading it by using a signer that runs entirely in your browser. Sign Simplified processes your document locally: you open the file, place your signature, and download the signed PDF, it is never transmitted to a server.

    Open the free signer

    Go to the Sign Simplified free signer. No account or installation is needed.

  2. 2

    Load your PDF or image

    Drop the file in or pick it from your device. It loads in your browser's memory only, nothing is sent over the network.

  3. 3

    Create and place your signature

    Draw it, type it in a handwriting font, or photograph it. Drag, resize, and rotate it anywhere on any page.

  4. 4

    Download the signed PDF

    Export a flattened PDF with your signature baked in. Throughout the process, the document stayed on your device.

Why signing without uploading matters

A signed contract often contains names, addresses, salaries, or bank details. Every upload-based tool asks you to hand that file to a third-party server before you can sign it. A local, in-browser signer removes that risk entirely: there is nothing to breach, retain, or share.

This is not just a promise: an automated test suite fails our build if the free signer ever makes a network request with your document.
