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, Fill Forms / Annotate, Watermark PDF. 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.
