A watermark is a semi-transparent text or logo overlaid on an image. It is one of the most common methods for protecting visual content copyrights and branding images.
Why Use a Watermark
- Copyright protection — makes unauthorized use of your photos more difficult. Removing a well-placed watermark without degrading image quality is virtually impossible.
- Branding — a logo or company name on photos increases brand recognition when shared on social media.
- Source identification — viewers immediately see who is the author or owner of the content.
- Client previews — photographers send clients watermarked photos for selection, and originals without the watermark — after payment.
Best Practices
A good watermark protects content without ruining the image viewing experience:
- 30–50% opacity — the watermark should be noticeable but not dominate the photo content.
- Position — bottom right corner for subtle branding, center — for maximum preview protection.
- Size — proportional to the image. A watermark that's too small is easy to crop out, too large — is distracting.
- Contrast — use white text for dark photos and dark text for light ones. A shadow or outline helps on busy backgrounds.
Text vs Graphic Watermark
A text watermark is an inscription (author name, website URL, copyright notice). It's easy to create and versatile. A graphic watermark is a company logo in PNG format with transparency. It looks more professional but requires prior preparation.
Client-Side Processing
