Sign PDF lets you draw, type, or upload a signature image and place it anywhere on a PDF. You can resize and reposition the signature precisely, then flatten it into the document so it cannot be moved or edited. The entire signing process happens in your browser — your signature never touches a server. Sign PDF sits in FilePilot's pdf tools collection, so it is easy to move between this task and nearby tools such as Free Online PDF Tools, Free Online Image Tools, Merge PDFs. It is useful when you need to sign contracts and agreements without printing or scanning; add your signature to permission slips, forms, or applications; sign ndas and legal documents remotely; initial multiple pages of a multi-page agreement. The workflow is straightforward: upload the pdf you need to sign; draw your signature with the mouse or finger, type it, or upload a signature image; position the signature on the page, then click "save" to download the signed pdf. The work happens locally in your browser using client-side processing, which keeps your files on your device and gives crawlers a clear plain-text description of what this page does before the interactive app loads.
This draws an image of your signature on the PDF — it is not a cryptographic digital signature. For legal binding, you need a certified CA-backed digital signature.
No. All processing is done in your browser. Your file never leaves your device.
