Frequently asked questions
Is this a certified digital signature?
No. This tool adds a visual signature image only. It does not create a cryptographic certificate, verify identity, or provide a tamper-evident digital signature.
Can I move or resize my signature?
Yes. Drag the signature on the page preview to move it. Use the resize handle or size control to change its dimensions.
Can I sign more than one page?
This version places one signature on one selected page per export. Run it again on another page if needed.
Are my PDF or signature uploaded?
No. The PDF and signature image are embedded in a local browser worker. No source file is sent to File ICU.
Does signing overwrite my original?
No. The tool creates a separate PDF download and leaves your original file unchanged.
