Frequently Asked Questions

How do I add my signature to the PDF?

Click “Draw Signature” to open the drawing canvas (mouse or touch), sign, then click “Add Signature” to place it on the PDF. Alternatively, click “Upload Signature” to use an existing image. Drag the placed signature to position it, and use the resize handle to adjust size.

Is my PDF safe? Is it uploaded to servers?

Your document never leaves your device. All processing runs locally in your browser — we have zero access to your file at any point. Completely private.
