Settings guide

Watermark settings guide:

  • ·Opacity 20–30%: Subtle brand placement for shared content — visible on close inspection, not distracting at normal viewing distance.
  • ·Opacity 30–50%: Standard copyright watermark — visible and readable, non-intrusive.
  • ·Opacity 50–70%: High-visibility protection — used on preview images in stock photo style.
  • ·Font size: 3–5% of image height for balanced text watermarks. Too small disappears on thumbnails; too large overwhelms the image.
  • ·Logo watermarks: PNG with transparent background works best. Position bottom-right or bottom-left for branding; tile for full protection.
  • ·Tiling: Covers the entire image with repeating watermarks — maximum deterrence for preview images.

Format comparison

Text vs image watermarks: Text watermarks are easier to create and clearly show copyright ownership. Image (logo) watermarks are more professional-looking and reinforce brand identity. For photographers, text is more practical. For businesses with a logo, image watermarks look better.

Visible vs invisible watermarks: Visible watermarks deter theft but are sometimes removed with AI tools. Invisible (steganographic) watermarks are embedded in pixel data and harder to remove but require specialised tools to verify. For most use cases, a visible watermark at 30–50% opacity is the practical choice.

About this format

Watermarking serves two distinct purposes: copyright protection and brand marketing. A photographer adds a subtle watermark to deter theft before sharing on social media. A business adds a logo to product photos to reinforce brand recognition at every touchpoint. The settings that work for one are wrong for the other.

This tool handles both: text watermarks with full font and colour control, and image watermarks where you supply a logo or image file. Position it at any corner, centre it, or tile it across the entire image for stock-photo-style protection. Opacity control lets you go from subtle (20%) to visible-but-not-intrusive (40%) to high-visibility (60%+).

Drop your image, add your watermark, download. Everything runs in your browser.

Frequently asked questions

What opacity should I use for my watermark?+
30–50% for text watermarks strikes the right balance — visible enough to deter theft, subtle enough not to ruin the image. For tiled watermarks meant to prevent use entirely, 50–70%. For subtle brand placement on shared content, 20–30%.
Can I watermark multiple images at once?+
Yes. Add multiple images and the same watermark settings apply to all — consistent positioning, opacity, and text or image watermark across your entire batch.
Will the watermark affect image quality?+
No. Watermarking is a compositing operation — pixels are blended at the specified opacity. It does not apply any compression or degrade the underlying image quality.
Can I use a logo as a watermark instead of text?+
Yes. Upload your logo (PNG with transparent background works best) as the watermark image. Position it at any corner or tile it across the whole image.
Are my files uploaded to a server?+
No. Watermarking runs in your browser.
