Frequently Asked Questions About Signing PDFs
Is this a legally binding signature?
This tool provides a simple electronic signature, which is a visual representation of your signature on a document. For many jurisdictions and purposes (like informal agreements or internal forms), this is sufficient. However, it is not a *digital signature*, which involves cryptographic verification. Please check your local regulations for your specific needs.
Is it safe to use this tool with sensitive documents?
Yes. This is the safest way to sign a file. Because the tool runs 100% in your browser, your PDF and your signature image are **never uploaded to any server**. Your private information remains on your computer at all times.
Why is my signed PDF file size different or not selectable?
To ensure 100% in-browser security, this tool renders each page of your PDF as an image, places your signature on that image, and then re-assembles those images into a new, secure PDF. This process (rasterization) means the final text may not be selectable, but it guarantees your file's privacy.
