When to use Sign PDF
Use this when you need to add your signature to a form, letter, or agreement without printing, signing by hand, and rescanning it. It is not a substitute for a certificate-based digital signature workflow — see the FAQ below if you need that instead.
How to Sign a PDF
- Select a PDF.
- Draw, type, or upload your signature.
- Position and resize it on the page.
- Optionally add a date or printed name, then export.
What this tool changes
- Adds a visible signature image and, optionally, a date or printed name to the pages you choose.
What it preserves
- All existing page content underneath the signature.
Good to know
- This adds a visible electronic signature. It is not a certificate-based digital signature, and it does not verify identity or cryptographically seal the document.
Frequently asked questions
- Is this a legally binding digital signature?
- PDF Editing Tools adds a visible electronic signature (an image of a signature), not a certificate-based digital signature. Legal enforceability depends on your jurisdiction and use case — review this yourself for important documents.
- Where are saved signatures stored?
- Only in your browser storage, if you explicitly opt in. They are never uploaded.
- Will signing invalidate an existing digital signature on the document?
- If the PDF already carries a certificate-based digital signature, editing it — including adding your signature — will likely invalidate that existing signature. PDF Editing Tools warns you before this happens.
- Can I reuse the same signature on multiple pages?
- Yes — once created, place it on as many pages as you need within the same session.
