How do I add a watermark to an image?

Upload the image, type the watermark text (or a copyright symbol + your name), pick font, size, color and opacity, then position it — centered, corners, or tiled across the whole image for stronger protection. A live preview shows the result in real time. When you're happy, download the watermarked image at full original resolution.

Is the watermark tool free?

Yes, completely free and unlimited. No signup, no watermark forced on top of yours (unlike some 'free' services), no image count limit. Protect portfolios, product photos, social media posts or client deliverables without paying and without getting a service logo pasted onto your work.

Does the watermark tool upload my images?

No. The image is rendered, watermarked and exported entirely in your browser using the Canvas API. Photos never leave your device, which matters when watermarking unreleased product shots, NDA client work, or private portfolio pieces — the whole point of watermarking is protection, and a tool that uploads defeats that instinct.

What's the most effective watermark style against theft?

A small, semi-transparent watermark in one corner is polite but easy to crop out. A large diagonal text across the center is the hardest to remove without leaving obvious traces, though it's also the most visually intrusive. A tiled pattern covering the whole image offers the best protection for proofs and previews. The tool supports all three — pick based on whether the image is a portfolio piece or a draft being reviewed.

Frequently asked questions

Can a watermark be removed by someone determined?

Yes — watermarks are a deterrent, not an absolute lock. Positioning over the subject and using lower opacity makes removal harder, but modern image tools can reconstruct backgrounds from surrounding pixels.

Should the watermark be opaque or transparent?

Aim for 30-50% opacity. Fully opaque watermarks harm the image; fully transparent ones are easy to overlook and easy to remove. Somewhere in the middle balances visibility and protection.

Can I watermark multiple images at once?

This tool handles one image at a time for fine control. For batches, apply the same settings to each file; the tool remembers them between runs.

Is my image uploaded?

No. The watermark is painted on the Canvas in your browser. Nothing leaves the device.

About image watermarking

Watermarking images helps protect your work from unauthorized use. A semi-transparent text overlay makes it clear who owns the image while still allowing the content to be viewed. Tiled watermarks provide the strongest protection, while corner placement is more subtle.
