Frequently asked questions
Is my PDF uploaded to a server?
No. The watermarking happens securely within your device's web browser. Your PDF is NEVER sent over the internet or saved on our servers.
Can I customize the watermark appearance?
Yes, you can easily change the text, font size, opacity, rotation, exact position (X and Y), and color of your watermark while seeing a live preview.
Can I apply the watermark to all pages at once?
Absolutely. Our tool allows you to apply the watermark to every page of your document automatically, or just the first page if you prefer.
Is there a file size limit?
Yes, for optimal browser performance, you can process PDF files up to 30MB.
Will the watermark degrade my PDF quality?
Not at all. Your document's original fonts, layout, vector graphics, and quality are perfectly preserved. The watermark is added seamlessly as a native PDF text layer.
