How to use
Sign PDF lets you draw your signature and place it anywhere on a PDF, then download the signed file — nothing is uploaded. Drop in your PDF, set the options, and download the result — the whole operation runs in your browser.
PDFs are processed locally with pdf-lib and pdf.js, so your documents stay private. It's completely free, with no sign-up, no watermarks and no limits on how often you use it.
Examples
Load a document, apply the change, and save the new PDF without any file ever being uploaded.
Once sign PDF shows your output, use the copy or download button to grab it — no retyping.
