Microsoft Visio is a powerful diagramming tool used across industries for creating flowcharts, organizational charts, floor plans, network diagrams, engineering designs, and more. While Visio offers a wide range of tools to visualize complex information, one essential feature often missing in its native toolset is custom watermarking. Whether you're sharing a Visio diagram with external stakeholders or protecting confidential blueprints, adding a watermark helps assert ownership, indicate document status (like "Confidential" or "Draft"), or brand documents with your company identity. That’s where the Add Watermark to VSDX File comes into play. The tool is designed to apply custom watermarks across various MS Visio file formats, such as: vdx, vsdm, vsdx, vssm, vssx, vstm, vstx, vsx, vtx. There are two main types of watermarks supported by our tool: ✅ Text Watermark: ? Input any desired text: "Confidential," "Draft Copy," "Company XYZ," etc. ? Supports multi-line text. ? Unicode support for multilingual text. ? Choose from a wide range of fonts. ? Adjust font size, color, alignment and styles. ✅ Image Watermark: ? Add your company logo or official stamp to reinforce authenticity and branding. ? Support a wide range of image file formats: avif, bmp, dib, emf, gif, heic, heif, ico, jpeg, jpg, png, psd, svg, tga, tif, tiff, webp, wmf. Each type of watermark (text/image) can be customized for options such as: ✔️ Position on the page (horizontal/vertical alignment). ✔️ Rotation angle (e.g., -45° diagonal). ✔️ Opacity level (transparency-level). ✔️ Scale (resize). One of the most powerful features in this tool is the Preview Panel, enhanced with zoom and pan capabilities — an interactive workspace where users can see exactly how their watermark will appear on the page — before saving a single file. Users can add watermarks to entire document (all pages) or custom pages. This capability provides a level of control and customization ideal for business, academic, and creative purposes. For custom pages, typing pages numbers and/or pages ranges separated by commas. For example: 1-3,5,8
