Sign Document Free Online — Add Signature to a Scan | Pixlane

Place a signature on a scanned document image and export a signed page as PDF or image with browser-based local processing.

Sign Document is useful when you already have a page image or scan and only need a practical signing step before sending, archiving, or sharing it. The workflow keeps the document local and adds the signature directly into the exported file.

How to Use It

  1. Upload your document image and wait for the local preview to load.
  2. Adjust the settings — Upload the document first, add the signature image as the second file, position the signing box, then export the signed page as PDF or image.
  3. Download the result after the tool renders on your device.

Why People Use Sign Document

Upload a clean signature image, then draw the placement box directly where the signature should sit on the document.

Formats and Output

Input: document image plus signature image. Output: PDF, PNG, JPG, or WebP. PDF is useful when you want a signed document file while image outputs fit lightweight approval flows.
