FAQ
Is this a qualified electronic signature?
No. The tool adds a visible signature image. It does not create a cryptographic or qualified signature.
Can I choose the position?
Yes. You can choose from several positions and adjust the size.
Is my signature stored?
No. The drawing is processed in your browser and is not transferred to LocalPDF.
Your PDFs stay on your device.
Many online PDF services upload documents to a server for processing. LocalPDF takes a different approach: the actual document processing happens in your browser. This is especially useful for invoices, contracts and other sensitive documents.
Note: JavaScript libraries used for PDF processing are loaded from external CDNs. Your IP address may therefore be transmitted to the CDN provider, but your PDF files themselves are not transmitted.
