How do I add a copyright watermark to my photos?
Type "© Your Name" or "© YourWebsite.com" in the watermark text field, choose a position (Bottom Right is most common), set opacity to 50–70% and click Apply. For maximum protection use the Tile position which repeats the copyright text across the entire image. Download free with no additional watermark added by this tool.
What is the best format for a logo watermark?
PNG with a transparent background is the best format for an image watermark. Transparent areas let the underlying photo show through while only your logo appears. If your logo is on a white background, that white will also appear on your photos — use a PNG with transparency to avoid this.
What opacity should I use for a watermark?
For visible copyright protection, 50–70% opacity is recommended — prominent enough to deter copying but not so strong it obscures the photo. For subtle corner branding, 30–50% works well. The Tile option works best at lower opacities (20–40%) so it does not overwhelm the image.
Does this tool upload my images to a server?
No — all watermarking is done entirely in your browser using the HTML5 Canvas API. Your images never leave your device at any point. This is especially important for confidential documents or unpublished photography before public release.
