What is Image Watermark?
A watermark marks an image as yours before it's shared publicly, which matters for photographers, designers, and anyone posting original work online where it could be screenshotted or reused without credit. A light, well-placed watermark deters casual misuse without ruining the photo.
This tool overlays custom text onto your image using the canvas, with control over position, size, opacity, and color. You see the watermark applied live as you adjust the settings, so you can balance visibility against how much it distracts from the photo itself.

Frequently asked questions
Can I add an image watermark instead of text?
The current tool adds text watermarks. For image watermarks (like a logo), you would need to use an image editor to overlay two images.
How do I make the watermark semi-transparent?
Use the opacity slider to reduce the watermark opacity. A value around 30-40% creates a visible but non-intrusive watermark that shows ownership without dominating the image.
Where should I position the watermark?
Bottom right or bottom left corners are standard for photos. Center watermarks are harder to remove but more visually intrusive. For professional use, corner placement is the common choice.
Can the watermark be removed?
A semi-transparent text watermark can be partially removed with image editing software. For stronger protection, use higher opacity and position the watermark over important details in the image.
Does watermarking reduce image quality?
Watermarking applies text on top of the image. The underlying image quality is unchanged. The output quality depends on the format and compression settings.
What font options are available?
Standard system fonts are available. Font size, color, and opacity can be adjusted to match your style.
