Frequently Asked Questions
Is this the same as a certified digital signature?
No. This tool adds a drawn electronic signature image to the PDF. Certified cryptographic signatures require a separate certificate-based signing service.
Where is the signature placed?
The signature is added to the first page of the PDF near the lower-left area, which fits many simple approval and acknowledgement documents.
Is my signed PDF uploaded?
No. The PDF and signature are combined in your browser, and the finished file downloads directly to your device.
