Frequently asked questions
Is it free and private?
Yes. Watermarking is free and runs locally in your browser; the file is not uploaded for this tool.
Is it safe? Are my files uploaded?
These tools run locally in your browser — for supported local operations your files are not uploaded to a server. Processing the document on your own device avoids sending it to a third party.
