What the tool does

Image Watermark adds a clear text mark to an image before you publish, share, or send it for review. It is useful for draft mockups, product photos, portfolio previews, social graphics, and client proofs where you want attribution or status to remain visible.

The watermark is rendered on a browser canvas, so the image does not need to be uploaded. You can choose the corner or center position, adjust opacity, and scale the text for small screenshots or large photos. The output downloads as a PNG copy, while your original image remains unchanged.

That separation matters in practice: you can send a marked proof to a client, post a preview online, or share a draft for feedback, and still keep the clean original for the final delivery. If the wording or placement needs to change, simply run the original through the tool again with new settings.

How to use it, step by step

1. Open the tool using the link above.
2. Add the image you want to watermark — for example, a photo, a screenshot, or a design preview.
3. Type your watermark text. This could be your name, your brand name, or a status word such as "Draft" or "Proof."
4. Choose where the watermark should sit. Pick a corner for a discreet mark, or the center when the image may be reposted without context and you want the mark to be hard to crop out.
5. Adjust the opacity. Lower opacity works well for proofs that still need to be viewed clearly; a stronger mark is better when the image may be shared beyond your control.
6. Scale the text so it suits the image. Small screenshots need a smaller mark, while large photos can carry a larger one without looking crowded.
7. Check the live preview. Look at the whole image, not just the watermark, and make sure the mark is readable without hiding the main subject.
8. Download the watermarked copy as a PNG. Your original file stays exactly as it was — the watermarked version is a separate download.

Practical tips

• Keep it readable but not aggressive. A watermark that shouts can distract from the photo itself. Start subtle, then increase opacity only if the proof really needs protection.
• Match the position to the purpose. A corner mark suits portfolio previews and social graphics, where the image should still shine. A center mark suits client proofs and draft mockups, where the status needs to be unmistakable.
• Test at the size people will actually see it. A mark that looks fine on a large photo can disappear on a small social post, or dominate a small screenshot. Preview at the final display size before you download.

Frequently asked questions

Can I add a logo watermark?

This version focuses on text watermarks. If you need broader image preparation, use the mini image editor workflow on ToolsFam for that work, and use this tool for clean text marks.

Does it change the original file?

No. The original image remains unchanged, and the watermarked copy is downloaded separately as a PNG.

Is my image uploaded anywhere?

No. The watermark is applied locally with the Canvas API in your browser, so the image does not need to be uploaded to a server.

What should I write as the watermark?

Keep it short: your name, your brand, or a single status word. Long sentences are harder to read at a glance and can clutter the image, especially on smaller photos.

Privacy note

Image Watermark runs 100% in your browser — files never leave your device. Your photos are processed locally, the watermarked copy is generated on your own machine, and nothing needs to be uploaded to use the tool.
