Watermarking Best Practices

Instagram / Pinterest — Copyright Protection

Protect your creative work. Use a subtle, 15–20% opacity watermark in a corner to claim ownership without ruining the user experience. It's a must-have for photographers and designers.

E-commerce — Branding

Adding a small brand logo adds professionalism. Note: Amazon strictly forbids watermarks on Main images, but they are great for secondary lifestyle shots to prevent image theft by competitors.

YouTube — Thumbnail Branding

Place your channel logo in the corner of your thumbnail. Keep it semi-transparent (40–60%) so it adds to your brand authority without distracting from the main message.

WordPress — Attribution

If your original blog images are featured in Google Image search, a subtle watermark with your URL helps drive traffic back to your site when others share your work.
