How this image watermark tool works
Type your mark — a copyright line, your handle, DRAFT — and this tool stamps it diagonally across the photo in semi-transparent text with a subtle outline so it stays visible on both light and dark areas. Everything happens in your browser; the original photo never leaves your device. The same honesty that applies to any watermark: it's a visible claim of ownership and a deterrent to casual reuse, not protection. Someone determined can crop or clone-stamp it out — which is why the mark goes across the middle, where removal costs the most.
Image watermark tips
- Short marks read strongest: © Your Name, @yourhandle, PROOF. The tool scales text to the image, and fewer characters means bigger letters.
- Watermark the copies you share; keep the clean original — clients pay for the version without the mark.
- The semi-transparent white with a dark outline stays legible on any background, from sky to shadow.
- A center-diagonal mark is harder to crop away than a corner signature — corners are the first thing thieves cut.
- For batches, keep this tab open and process photos one after another — each takes about a second.

Watermark Image — common questions
Latest questions readers ask us about this topic.
Is my photo uploaded anywhere?
No. The watermark is drawn onto the image by your own browser and the marked copy downloads from your device. For unpublished work — the exact photos people watermark — that privacy matters.
Can a watermark be removed?
With effort, yes: cropping, clone-stamping and AI inpainting can defeat any visible watermark from any tool. Treat it as attribution and deterrence, not security. The center-diagonal placement here maximizes the effort required, which is all any watermark can honestly do.
Where should I put a watermark?
Across the middle if deterrence is the goal — corner marks get cropped in seconds. This tool uses a center diagonal for exactly that reason. If aesthetics matter more than protection, a small corner credit is kinder to the image; add it in an editor instead.
Does watermarking reduce image quality?
PNGs stay lossless. JPGs re-encode once at 92% quality, which is visually identical for photos. The watermark text itself is drawn at full resolution, so it stays crisp when zoomed.
