What does image watermark do?
Flatten a single-line text watermark onto one image with placement at top left, top right, center, bottom left, or bottom right, plus selectable color, opacity, and size. Long text is automatically reduced to fit within 88% of the image width and receives a dark outline for legibility.

What to expect
How it works
The source pixels are drawn first, then bold system-font text is measured and reduced if it would exceed the safe width. Positioning includes padding based on image size. The browser draws a dark stroke plus the selected fill color and opacity before flattening everything into WebP, JPEG, PNG, or AVIF.
Know before using
Limits and edge cases
- This tool supports one text line on one image, not logo files, tiled watermarks, rich typography, or batch placement.
- A flattened watermark discourages casual reuse but is not tamper-proof; it can be cropped or edited, and the exported image no longer has editable watermark layers.
Common questions
Image watermark FAQ
Is image watermark free to use?
Yes. Image watermark is free to use.
Does image watermark keep my work private?
Yes. Your work stays private while you use the tool — nothing you enter is uploaded.
Does adding a watermark change the image dimensions?
No. The output canvas uses the source width and height. Only the pixels and selected file encoding change.
How does very long watermark text fit?
The renderer starts at the chosen text size, measures the line, and scales the font down when necessary so the text stays within 88% of the canvas width.
