Choose Watermark Type
Select either 'Text' to add custom text (like your name or '© Copyright') or 'Logo' to upload your brand logo or stamp.

Apply and Download
Click 'Apply & Download' to generate your watermarked image. The output is ready to share or publish.
Pro Tips
- Use 30-50% opacity for subtle watermarks that don't obscure the image.
- Diagonal watermarks (45° rotation) are harder to remove.
- For logos, use PNG files with transparent backgrounds for best results.
Common Issues
Watermark too dark or too light?
Adjust the opacity slider. For subtle watermarks, use 20-40% opacity. For prominent branding, use 60-80%.
Logo has white background?
Use a PNG logo with a transparent background. If you only have JPG, use our 'Remove Background' tool first.
