Frequently asked questions
Why watermark your documents?
A watermark saying who the document is for and why limits fraudulent use of your ID or payslips.
Can I remove the watermark later?
While you are in the editor, yes. Once the PDF is downloaded, it is part of the pages.
Does the text stay readable?
Yes, set the intensity so the watermark is visible without getting in the way.
Is it really free?
Yes. With a free account you download 3 documents a month and make 10 Assistant requests, with no credit card and no ads. PDFmoji Pro (€5.99 a month, cancel anytime) removes these limits.
