Add a text watermark to an image — position, size, opacity, and color, all adjustable.
This adds a text watermark directly onto an image using canvas — useful for marking ownership on photos you share publicly (a portfolio, a marketplace listing) without needing a design tool.
Position, size, color, and opacity are all adjustable and update live in the preview. Lower opacity (40-60%) tends to look more like a professional watermark and less obtrusive than a fully opaque one, while still discouraging unauthorized use — the goal is usually visible-but-unobtrusive rather than impossible to remove.
This is a straightforward text overlay, not a tamper-resistant watermark — a determined person can crop or paint over a corner watermark. It's best suited to casual protection and clear attribution, not high-stakes copyright enforcement.
It discourages casual reuse and adds visible attribution, but a determined person can crop the watermark out or paint over it. For stronger protection, consider a larger, more central watermark, though that trades off against how presentable the image looks.
This version supports text watermarks only. For a logo overlay, you’d currently need to composite it in an image editor.
40-60% is a common sweet spot — visible enough to discourage reuse without making the underlying image hard to see.
