What Is a PDF Signature Tool?
A PDF signature tool allows users to place a visual signature onto a PDF document. This can be useful for forms, applications, agreements, letters, invoices, authorization documents, and other files that require a handwritten signature.
Instead of printing a document, signing it with a pen, scanning it, and sending it back, you can use a browser-based tool to place your signature directly on the PDF.

Frequently Asked Questions
Can I sign a PDF without installing software?
Yes. This browser-based tool is designed to let you create and place a signature without installing a dedicated PDF signing application.
How do I create my signature?
Draw your signature inside the signature box using your mouse, trackpad, stylus, or touchscreen. You can clear it and draw it again whenever necessary.
Can I move the signature after adding it?
Yes. After adding the signature, you can drag it around the PDF page and place it where you need it.

Does the tool work on phones?
Yes. The interface is responsive and the signature canvas supports touch input on compatible mobile devices.
Can I sign multiple pages?
Yes. You can navigate through the pages of the PDF. A signature can be placed on the currently displayed page. If you need signatures on multiple pages, place the signature on each required page before downloading.
Why can't my PDF be opened?
Some PDF files may use encryption, passwords, unusual structures, damaged data, or features that are not supported by browser-based PDF processing. Try opening the document in a standard PDF reader first or use another PDF file.
Is my PDF uploaded to a server?
The tool is designed to process the selected document inside your browser. The signing operation itself does not require uploading the PDF to a remote signing server.
What should I do if I see an error?
Make sure the file is a valid PDF and is not password protected. Refreshing the page and trying a different PDF can also help. The tool provides a more specific error message when possible.
Is a visual PDF signature legally valid everywhere?
Legal requirements for electronic signatures vary by country, document type, organization, and circumstances. A visual signature added to a PDF should not automatically be assumed to satisfy every legal or regulatory requirement. Check the applicable requirements for your situation when a legally binding electronic signature is required.
