Frequently Asked Questions
Is this a legally certified digital signature?
No. This tool embeds your signature as an image into the PDF. It is not a certificate-based cryptographic signature, so for contracts that require certified signing, use a dedicated e-signature service instead.
Can I sign a specific page, not just the last one?
Yes. Set the page number before placing the signature — the tool signs exactly that page and leaves the rest untouched.
Are my PDFs uploaded anywhere?
No. The PDF is opened, signed and saved entirely in your browser. Your document never leaves your device.
Why can't I see the signature on the preview before downloading?
The preview shows your original PDF for reference while you choose the page and position. The signed result is in the downloaded file — open it to check the placement, and re-run with a different position if needed.
