If you sell or distribute digital products—eBooks, design templates, stock photos, or educational resources—your preview or free versions need to be clearly marked as 'SAMPLE' or 'PREVIEW'. Our Add Sample Watermark to PDF Online Free tool is the specialist for this task. It's designed to protect your revenue by ensuring that free previews cannot be mistaken for, or used as, the paid product. The tool allows you to create a pervasive 'SAMPLE' watermark. For maximum protection, you can use the 'Tile' feature, which covers the entire page with a repeating grid of the word 'SAMPLE'. This makes the document unusable for professional purposes but perfectly viewable for evaluation. You can also add a large, diagonal central stamp. This is the ethical and commercial shield for your digital goods. It lets potential customers explore the quality of your work while firmly protecting your full-resolution, usable assets from piracy. The processing is client-side, meaning your original, high-value digital products are not uploaded or exposed. Secure your business model and let your work sell itself safely, with a clear, professional barrier between preview and purchase.
