How to Add a Text Watermark

4. Adjust font size, color, opacity, and position.
5. Download the watermarked image to your device.

Best Watermark Settings

For portfolio images, use low opacity so the watermark is visible but not distracting. For client proofs or stock previews, use a repeated tiled watermark because it is harder to crop out.

If your image is very large, compress it after watermarking with the Image Compressor. For web uploads, you can also convert it to WebP to reduce file size.

When Should You Watermark Photos?

Watermarks are useful for photography portfolios, product previews, social media posts, real estate photos, client proofs, and digital artwork. They are especially helpful when you want to share a preview before sending the final unmarked image.
