A watermark marks an image as yours and makes casual reuse harder. It will not stop a determined person — watermarks can be cropped or edited out — but it does deter unattributed sharing and keeps your name attached as the image travels.
How to use the Image Watermark
- Upload the image you want to watermark
- Type your watermark text
- Adjust font size, colour and opacity until it is readable but not distracting
- Choose a position, then download the watermarked image
Making a watermark that works
The tension is always between visibility and intrusiveness. A watermark nobody notices does nothing; one that dominates the image ruins it.
- Opacity 30–50% is the usual sweet spot — legible without competing with the subject.
- Position matters. Corners are unobtrusive but trivially cropped out. Across the centre is far harder to remove but much more intrusive.
- Size it relative to the image. A watermark sized for a 4000px photo becomes illegible when that photo is displayed as a 400px thumbnail.
What a watermark does and does not protect
A watermark is a deterrent and an attribution mechanism, not copyright protection. Copyright exists automatically the moment you create the work, whether or not it is marked.
For images that genuinely matter, combine a visible watermark with keeping the original high-resolution file, and publish only lower-resolution versions publicly. The original is your proof of authorship.
Frequently asked questions
Can a watermark be removed?
Yes, with effort — cropping removes corner watermarks, and content-aware fill in image editors can remove many others. Watermarking raises the cost of reuse; it does not make it impossible.
Can I use a logo image instead of text?
This tool does text watermarks only. For a logo you would need an editor that supports compositing one image over another with an alpha channel.
Where should I put the watermark?
Bottom-right is the convention and stays out of the way. If deterring reuse matters more than aesthetics, place it across the centre at low opacity — that is much harder to crop out without destroying the image.
Does watermarking reduce image quality?
The watermark is drawn onto the image and the result is re-encoded, so there is some loss if you export to JPEG. Export to PNG if you want no additional loss.
