If you've ever watched your photos spread across the web without credit, you already know why watermarks matter. This tool lets you stamp any text onto a JPG, PNG, or WEBP image — your name, website URL, social handle, or copyright notice — and fine-tune the font size, opacity, color, and placement until it fits the photo perfectly. Every control updates the output instantly, so you can preview exactly how the watermark will look before saving.

All processing happens entirely in your browser. Your photos never leave your device, which means you can watermark unpublished work, client previews, or personal portfolios without any privacy risk. If you need stronger protection, turn on the diagonal tile repeat option: it tiles the watermark across the entire image at an angle, so even cropping a corner won't remove it.

The tool supports any text your browser can render, including Unicode characters and emoji. After adding an image, type in your watermark text, dial in the settings, and click Apply. A preview appears alongside a download button that saves the result in the original format — JPG stays JPG, PNG stays PNG, WEBP stays WEBP — so there's no extra conversion step.

How to Use

  1. 1

    Select an image

    Drag in the photo you want to watermark, or add it with the file picker. JPG, PNG, and WEBP are supported.

  2. 2

    Enter text and style settings

    Type your watermark text, then adjust font size (2-15% of image width), opacity (10-100%), and text color to match your photo.

  3. 3

    Choose a position or enable tiling

    Pick one of the nine positions in the 3x3 grid, or turn on the diagonal tile repeat to spread the watermark across the whole image.

  4. 4

    Apply and download

    Click Apply watermark to see a preview. When you're happy with the result, hit Download to save the file.

When It's Useful

Protect blog and portfolio photos

Add your name or website to original photos so anyone who shares them carries your credit along with the image.

Promote your social account

Watermarking with your social handle turns every share into a discovery path — viewers can find you even when the image is reposted without a link.

Send client previews safely

Stamp a SAMPLE watermark over drafts or mockups so clients can review the work without receiving a clean copy they could use as-is.

Block crop-and-strip removal

The diagonal tile mode repeats the watermark everywhere, so cropping any corner still leaves the mark behind.

Tips

  • White text at 60-70% opacity blends naturally over most photos and stays legible against both bright and dark areas.
  • Use dark text on light images and white or light text on dark images for the best contrast.
  • Setting font size to around 4-6% of the image width is a good balance: noticeable but not distracting.
  • In tile mode, keep the font size low (2-3%) so the repeated text doesn't overwhelm the photo.
  • For a legally clear copyright notice, combine the © symbol with the year and your name, for example: © 2025 Your Name.
  • PNG preserves transparency — if your source image has a transparent background, use PNG to keep it that way after watermarking.

FAQ

Can I use non-English text in the watermark?

Yes. The tool uses the browser's default sans-serif font, which renders any characters your browser supports, including CJK scripts, Arabic, emoji, and more.

Are my images uploaded to a server?

No. Everything runs 100% in your browser, and your photos are never sent anywhere. It's safe to use with unpublished or sensitive images.

Does the format change after watermarking?

No. The original format is preserved: JPG stays JPG, PNG stays PNG, and WEBP stays WEBP. Use the Convert Format tool if you need a different format.

What is the diagonal tile repeat option?

It tiles the watermark text across the entire image at a -30 degree angle. Because the text covers the whole image, simple cropping cannot remove it.

What opacity level should I use?

30-50% is subtle and keeps the photo easy to view. 60-80% is more assertive and harder to overlook, which works better as a deterrent.

Will a JPEG watermark have a white background?

JPEG doesn't support transparency, so any transparent areas are filled with white automatically. Use PNG if you need to preserve a transparent background.

Can I re-apply the watermark with different settings?

Yes. Adjust the settings and click Apply watermark again at any time. The tool always starts from the original image, so you can experiment freely without worrying about stacking effects.
