Why Use a Watermark?
- Protect your work — makes it harder to use your photos without credit
- Brand visibility — your name travels with the image when shared on social media
- Prove ownership — useful if you ever need to dispute copyright
- Client proofing — share previews without giving away full-resolution images
- Professional appearance — shows that the image belongs to a specific business or creator
After Watermarking — Next Steps
Once you have watermarked your image, you may want to:
- Compress the image — reduce file size before uploading to a website or social platform
- Convert to WebP — modern format with better compression for web use
- Resize the image — adjust dimensions for specific platform requirements
- Convert to PDF — combine watermarked images into a PDF portfolio
