About this tool

Sign PDF answers searches like sign pdf online free, add signature to pdf, electronically sign a document, and esign pdf without an account. ScanText at scantext.net lets you draw your signature with a mouse or finger — or upload a photo of it — then drag it to the exact spot on any page and resize it before downloading, all in your browser. It's the quick way to sign a contract, consent form, or letter without printing and scanning. Because the PDF is processed on your device, your document and signature never reach our servers — important for anything personal or legal. No account, no watermark, and the signature is placed as an overlay on top of your original page.
