Image Watermark Tool

Protect and Brand Your Images with a Custom Watermark

When a photo leaves your hands, a watermark is the simplest way to keep your name attached to it. Photographers mark preview galleries so clients cannot use unpaid images; shops stamp product photos that competitors love to “borrow”; creators add a handle so reposted work still points back to them; businesses mark internal documents as drafts or confidential. This tool adds a fully customizable text watermark to any image directly in your browser — the photo is never uploaded, which is exactly what you want when the image is valuable enough to protect.

How to Watermark an Image

1. Load a JPG, PNG or WebP image by dragging it onto the upload area.
2. Type your watermark text — a name, brand, URL, social handle or a word like CONFIDENTIAL.
3. Choose the position: any of the four corners, the center, or Tile to repeat the text diagonally across the entire image.
4. Adjust font size, color, opacity and rotation with the live sliders until it looks right.
5. Check the real-time preview, then download the watermarked copy. Your original stays untouched.

Choosing Between a Corner Mark and a Tiled Watermark

The two styles serve different purposes. A discreet corner watermark at 40–60 percent opacity credits the image without spoiling it — ideal for portfolio pieces, blog photos and social posts where aesthetics matter. A tiled, diagonal watermark across the whole frame is the protective option: it cannot be cropped away and is tedious to remove, which is why proof galleries, stock previews and sensitive documents use it. A practical middle ground for product photos is a centered watermark at low opacity, large enough to overlap the subject so cropping cannot avoid it.

Settings That Produce Professional Results

• Opacity 30–50 percent usually reads clearly without burying the photo. Full opacity is rarely necessary except on documents.
• White text suits dark images, black suits light ones. If the background varies, white at moderate opacity with a subtle shadow survives most surfaces.
• Rotation of 30–45 degrees is the convention for tiled marks — it reads naturally and resists simple inpainting tools better than horizontal text.
• Size with intent: a credit line can be small; a deterrent should span a meaningful fraction of the image width.

Honest Expectations About Watermark Security

No watermark is unremovable — sufficiently motivated people with editing skills can reconstruct the pixels behind a small corner mark. What a watermark really does is change the economics: a tiled mark across important detail makes theft more work than licensing, and any removal attempt on a marked image demonstrates intent. For everyday protection, that is enough to stop the casual right-click-and-repost behavior that accounts for most image misuse. Because this tool runs entirely client-side, you can safely watermark unreleased products, legal documents and private photos: nothing is transmitted, nothing is stored, and the only copy of the watermarked file is the one you download to your own device.

Finally, think about where the watermarked copy fits into your workflow. The smart pattern is to keep two versions of every important image: the clean original safely archived, and the watermarked copy as the only version that ever gets uploaded or emailed. Because this tool never modifies the source file, that workflow happens naturally — you load the original, download the marked copy under its suffixed name, and the two never get confused.
