FAQ
Q: Is my PDF uploaded to a server?
A: No. All processing is done locally in your browser using pdf-lib. Your file never leaves your device.
Q: Can I change the watermark style?
A: Yes. You can adjust the text, font size, opacity, color, and position (diagonal or horizontal center).
Q: Does the watermark affect the original PDF?
A: No. The tool creates a new watermarked PDF file for download. Your original file is untouched.
