Guide
The image watermark tool adds text or logo overlays directly in your browser, with adjustable position, opacity, rotation, and export format for publishing and copyright workflows.
Watermark Types
- Text watermark: add brand name, author name, or copyright text with custom font, color, opacity, and rotation.
- Image watermark: upload a logo or icon, then adjust scale and opacity for consistent brand presentation.
Use Cases
- Add store branding to ecommerce product images
- Attach account names or copyright marks to social media visuals
- Apply consistent watermark style to photography publishing
Tips
- Keep opacity around 30% to 70% to balance visibility and content clarity.
- For subject-heavy photos, place watermarks near corners to avoid blocking key details.
- Choose JPG/WebP for smaller files and PNG when transparent details matter.
