Frequently Asked Questions

Is this a legally binding electronic signature?+
This tool creates a visual signature on the PDF. For legal purposes, the validity depends on your jurisdiction. Many countries accept visual signatures on PDFs. For formal contracts, consider using a dedicated e-signature service with audit trails.
Can I sign multiple pages?+
Currently the signature is placed on one page. For multi-page signing, download the signed PDF and re-upload it to add signatures to additional pages.
Are my documents safe?+
Yes. Everything runs in your browser. Your PDF and signature never leave your device. No data is sent to any server.
Can I use a transparent signature?+
Yes. Upload a PNG image with a transparent background and it will overlay cleanly on the PDF content.
What happens to the drawn signature quality?+
The drawing canvas captures your signature at high resolution. The signature is embedded as a PNG image in the PDF, maintaining smooth lines and detail.
Can I sign a password-protected PDF?+
Yes, as long as the PDF allows modification. If the PDF is locked, use our PDF Unlocker first to remove the password.
Is there a watermark on the output?+
No. The signed PDF is completely clean with no watermarks, branding, or attribution.
Can someone remove my signature after?+
The signature is embedded as an image in the PDF content. It cannot be easily removed without specialized tools. For additional security, use our PDF Flattener after signing.
