Quick answer: A watermark adder overlays text on a photo to mark ownership or discourage reuse. This tool lets you choose the position (a corner or the center), the size and the opacity, or repeat the text in a diagonal pattern across the whole photo, which is harder to crop out than a single corner mark. Everything runs in your browser; the photo is never uploaded.

Type your watermark text, such as your name, a copyright line or a website address, and place it on a corner, the center, or repeated in a diagonal pattern across the whole photo. Adjust the size and opacity, then download the result.

The image is processed in your browser and is never uploaded, so this works for photos you have not published yet.

Choosing a position

  • A corner is the least visually intrusive and is enough to discourage casual reuse.
  • Repeated across the whole image is harder to remove by cropping, which matters more for photos you are worried about being copied.
  • Opacity around 30 to 50% is usually readable without overwhelming the photo underneath.

A worked example

Example. A photographer sharing preview images online sets the watermark to their studio name, chooses "Repeat across the whole image" and a low opacity, so the watermark is visible but does not stop a client from judging the photo.

Real-world examples

A freelance photographer sharing proofs with a client sets the watermark to their studio name, chooses the repeated pattern and a low opacity, so the client can judge the photos without being able to lift a clean copy.

A small shop listing a product photo online adds their store name in a bottom corner at a moderate opacity, which is enough to discourage reuse without covering the product.

Common mistakes to avoid

  • Using a high opacity that makes the photo hard to see. Around 30 to 50% is usually enough to be visible without overwhelming the image.
  • Relying on a single corner watermark for strong protection. It is easy to crop out; the repeated pattern option is harder to remove.
  • Watermarking a photo you plan to print large. Text sized for on-screen viewing may look small on a large print; increase the text size first.

Frequently asked questions

Can I remove the watermark later?

No, this tool does not do that, and this version only adds a text watermark, it does not overlay a logo image.

Is my photo uploaded?

No. Everything happens in your browser, and the photo is never sent to a server.

Does a corner watermark protect my photo from being copied?

It discourages casual reuse but can be cropped out. For stronger protection, use the repeated pattern option.

What file format does it download as?

PNG, which keeps the watermark and the photo at full quality.
