Frequently asked questions
How do I add a watermark to a PDF for free?
Upload your PDF to the tool above, type your watermark text (for example “DRAFT” or “CONFIDENTIAL”), choose the style, size and transparency, then click “Add Watermark”. The watermarked document downloads instantly.
Can I change the watermark transparency?
Yes. Choose Light, Medium or Dark transparency so the watermark sits softly behind your content or stands out more clearly.
Where does the watermark appear?
Pick Center diagonal (large text across the middle of every page) or a small corner watermark: top left, top right, bottom left or bottom right.
Is my PDF uploaded to a server?
No. Watermarking happens entirely in your browser. Your file never leaves your device.
Will the watermark cover my PDF text?
The watermark is drawn semi-transparent, so your original text stays readable underneath. Use the Light transparency option for the softest effect.
