FAQ
Is a drawn signature legally valid?
In most countries, an electronic signature is legally binding if it shows intent to sign and is associated with the signed document. Simple drawn signatures are accepted for most business documents. For highly regulated transactions (property transfers, court documents), a qualified electronic signature (QES) with identity verification may be required.
Is my PDF uploaded to your servers?
No. All processing happens in your browser using JavaScript. Your PDF never leaves your device. This makes it safe for confidential documents.
Can I sign multiple pages?
Yes. Position your signature on each page where a signature is required.
What file size can I sign?
Browser-based PDF tools work best with files under 50 MB. Very large PDFs may slow down the browser but are not rejected.
