Why add a watermark to images?
Watermarks protect your images from unauthorized use and theft. They serve multiple purposes: COPYRIGHT PROTECTION - prevents others from claiming your work, BRANDING - promotes your brand/business on shared images, ATTRIBUTION - ensures credit when images are shared, DETERRENT - discourages casual theft (though not foolproof), PROFESSIONALISM - adds credibility to your work. Watermarks are essential for photographers, graphic designers, artists, businesses, content creators, and anyone sharing valuable visual content online.
What makes a good watermark?
A good watermark balances visibility and subtlety. Best practices: USE PNG FORMAT with transparent background (no white box), KEEP IT SIMPLE - complex watermarks distract from content, RIGHT SIZE - typically 10-30% of image width, APPROPRIATE OPACITY - 30-70% usually works (you want it visible but not overwhelming), STRATEGIC PLACEMENT - corners or edges are common (harder to crop out without affecting composition), CONSISTENT BRANDING - use the same watermark across all images for brand recognition. Avoid: covering the main subject, making it too large or too small, using bright colors that clash.
Where should I position my watermark?
Position depends on your goal: BOTTOM-RIGHT - most common, traditional placement, easy to see. BOTTOM-LEFT - good alternative if bottom-right interferes with subject. CENTER - maximum protection but most intrusive, use lower opacity. CORNERS - harder to remove without cropping significant portions. REPEATED/TILED - maximum protection but affects aesthetics (not available in this tool). TOP positions - less common but useful for specific compositions. Consider your image composition—don't cover important subjects. For maximum protection use center or tiled watermarks. For subtle branding use corners with moderate opacity.
