Three ways to create your signature: draw it with mouse or finger, type your name with an elegant handwriting font, or import an image of your existing signature. Save your signature locally for easy reuse. A quick check can prevent problems later. Always check the output file before sharing it.
Position signature precisely
Place your signature exactly where you want on the document. Resize it, rotate it, and adjust its position with drag and drop. Preview the result in real-time before downloading the signed PDF. Keep the original until you have approved the result. Always check the output file before sharing it.
Keep the original file
Finally, test the file in the app or service where it will be used and keep the original until the finished version has been fully reviewed. Before running the tool, check the source file and define the result you actually need so that you only change settings that matter for the final use.
Add date, initials, and additional fields
Complete your signature with automatic date, your initials on each page, or additional mentions like "Read and approved". Create a paraph for multi-page documents requiring validation on each sheet. The final format should match how you plan to use it. A quick check can prevent problems later.
