About this tool
A visible watermark discourages copying and makes the status of a document obvious. Tiled watermarks are the best choice for ID copies you send to landlords or banks, because they're hard to remove.
Any script
Hindi, Arabic, Chinese and emoji all render correctly, unlike tools limited to basic fonts.
Centered or tiled
One bold diagonal stamp, or a repeating pattern that's hard to crop out.
Your files stay yours
Watermarking sensitive documents shouldn't mean uploading them.
Add watermark FAQ
Should I watermark copies of my ID?
It's a good habit. A tiled watermark like 'For rental application only, 2026' limits how the copy can be reused.
Can the watermark be removed?
Any watermark can be edited out by someone determined, but tiled watermarks across the content make that much harder.
Are my files uploaded to a server?
No. pdfy processes your files inside your browser using your own device. Local tools do not upload documents. If you choose Save draft, that draft is stored only in this browser. You can confirm it in your browser's network panel: no file is ever sent.
Is it really free? Are there limits?
Yes, it is free with no sign up, no watermark on your output and no daily task limit. Because your device does the work, the only practical limit is your device's memory.
