Independent from the signature toggle above — contracts usually want initials on every page but the full signature only on the last.

Appends one extra page recording the signer name, signing method, a local device timestamp, and a SHA-256 fingerprint of the original document — for your own records. This is your device's clock, not a certified trusted-timestamp-authority signature.

Sign a PDF or document online — free

DocuSmartly lets you sign a PDF online for free in seconds — no account, no software install, and no watermark. Draw your signature, type your name in a handwriting-style font, or upload a photo of your real signature, then place it exactly where it belongs and download the signed document.

Unlike most online signature tools, every step happens entirely in your browser. Your PDF never leaves your device and is never uploaded to a server — so it stays completely private, which matters for contracts, agreements, offer letters and any sensitive paperwork.

How to sign a document online

  1. Upload your PDF — drag and drop the file or click to browse.
  2. Create your signature — draw it with your mouse or finger, type it, or upload an image of your handwritten signature.
  3. Place it on the page — drag the signature where you want it and resize to fit.
  4. Download — apply it to one page or all pages and save your signed PDF.

Is an electronic signature on a PDF legally valid?

For high-stakes legal instruments, check the specific requirements that apply to your document.
