What is Watermark Images ?

If you publish photos, artwork, or product images anywhere online, you already know they get reposted without credit. A watermark is not a security system, but it is an honest, visible claim of ownership that survives screenshots and re-uploads. This tool stamps a text watermark onto your images — your name, studio, handle, or copyright notice — with control over the details that make a watermark look professional rather than slapped on: font size, color, opacity, and position in any corner or centered.

The opacity setting deserves the most attention. Around 30–50% is usually right: clearly readable, but not competing with the image for attention. Full-opacity watermarks in bright colors are the fastest way to make a photo unusable as promotion. Position matters too — bottom-right is conventional, but a watermark in a corner can be cropped off, which is a legitimate reason to choose the center for images you expect to be reposted aggressively. There is also an option to include the filename, useful when you are marking batches of proofs or drafts for review.

Watermarking runs entirely in your browser: your images are processed on your own device and never uploaded, which is exactly the assurance you want when the images are unpublished client work or portfolio pieces.

Practical advice for good results: keep the text short — a name or handle, not a sentence — because long text must either shrink illegibly or dominate the frame. If your images vary wildly in size, watermark them in batches of similar dimensions so one font size works for the whole set. And keep an unwatermarked original; you will want it for licensed uses, prints, and your own archive.
