You want readers to notice the stamp but still be able to read the content underneath. Here&#8217;s what to consider:<\/p>\n<p><strong>Opacity:<\/strong> 25\u201335% is the sweet spot for most documents. Low enough to read content behind it, high enough to be clearly visible. Going above 50% makes the watermark too dominant and hard to read through.<\/p>\n<p><strong>Angle:<\/strong> 45\u00b0 diagonal is the most recognisable watermark style and the hardest to crop out. Horizontal works well for header or footer style stamps. Vertical is less common but effective for narrow documents.<\/p>\n<p><strong>Text length:<\/strong> Keep it short. &#8220;CONFIDENTIAL&#8221;, &#8220;DRAFT&#8221;, &#8220;SAMPLE&#8221; or your company name. Long phrases at an angle become hard to read and look cluttered.<\/p>\n<p><strong>Size:<\/strong> Larger text (60\u201380pt) works well for diagonal watermarks on A4 or Letter pages. Smaller text suits narrow or portrait documents where space is limited.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"When_Should_You_Add_a_Watermark_to_a_PDF\"><\/span>When Should You Add a Watermark to a PDF?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>Before sending contracts for review<\/strong> \u2014 stamp &#8220;FOR REVIEW ONLY&#8221; so recipients know it is not the final version<\/li>\n<li><strong>When sharing proposals<\/strong> \u2014 add &#8220;SAMPLE&#8221; to prevent the content being used without payment<\/li>\n<li><strong>For internal documents<\/strong> \u2014 &#8220;INTERNAL USE ONLY&#8221; makes the intended audience clear<\/li>\n<li><strong>When distributing drafts<\/strong> \u2014 &#8220;DRAFT&#8221; prevents confusion if multiple versions are circulating<\/li>\n<li><strong>To brand distributed content<\/strong> \u2014 adding your website URL or company name to every page keeps your brand visible even when documents are forwarded<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Does_a_Watermark_Protect_Your_PDF\"><\/span>Does a Watermark Protect Your PDF?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A watermark is a deterrent, not a security system. It makes it visually clear that a document is confidential or protected, and it discourages casual copying or sharing. However, a determined person with PDF editing software could potentially remove it.<\/p>\n<p>For documents requiring stronger protection, combine a watermark with password protection. PDFix currently handles watermarking \u2014 password protection is a feature coming soon.<\/p>\n<p>For most everyday use cases \u2014 sharing drafts, protecting proposals, branding distributed documents \u2014 a watermark is entirely sufficient and the industry standard approach.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Watermark_PDF_on_iPhone_and_Android\"><\/span>Watermark PDF on iPhone and Android<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>You do not need to install an app to add a watermark to a PDF on your phone.
