A practical guide

Set the page and position for the signature mark.

  1. Choose a PDF and draw a mark, upload a PNG/JPG, or enter a typed name/date stamp.
  2. Set the page, width, position and opacity using the available controls.
  3. Create the copy and inspect the mark's placement on the chosen page.

Try this example

Place a typed name and date stamp on the designated page of a workflow packet. Check that the mark is visible and does not cover instructions.

Before

Input and expected output for this task. Illustrative example.

Before you start: This is a visual mark, not a certificate-based digital signature, identity check or signature request. Existing digital signatures may be invalidated; it is not redaction.

Inspect the stamped copy
What you get

A local drawing or PNG/JPG visual signature with page, width, position and opacity controls, or a typed label/name/date stamp. Drawings are cropped to their ink bounds.

Limits and important details

No certificate, identity verification or signature requests; existing digital signatures may be invalidated. Images: 5 MiB/4 MP. PNG transparency and JPG backgrounds remain. Typed stamps support Latin, Greek, Cyrillic, Hebrew, Arabic, Chinese, Japanese and Korean letters. Not redaction. Small or unsupported page geometry is rejected.

Example

Set Overlay pages to 2 and position to 95 / 95 for bottom-right placement. Select Sign PDF, then inspect Preview latest PDF. Clear workspace removes retained documents and drawing state.
