Image Watermark

What is this tool?

Image Watermark is a client-side editor that overlays custom text onto a photo as a watermark. You control the text content, font, size, color, opacity, position, and rotation, and can apply it once or as a repeating pattern across the image.

When to use it

  • Watermarking photography proofs before sending them to a client
  • Adding a brand name or website URL to product photos before sharing publicly
  • Marking draft images as "SAMPLE" or "PROOF" so they aren't mistaken for final files
  • Protecting personal photos shared on social media or a portfolio site
  • Labeling screenshots or graphics with attribution text

  1. 1Open Image Watermark and upload your photo.
  2. 2Type the watermark text you want to apply.
  3. 3Adjust font, size, color, opacity, and rotation.
  4. 4Position the watermark, or choose a repeating pattern across the image.
  5. 5Preview the final result.
  6. 6Download the watermarked photo.

Frequently asked questions

Can I make the watermark repeat across the whole image?

Yes, the tool supports a repeating tiled pattern in addition to placing a single watermark instance.

Can I adjust how visible the watermark is?

Yes, opacity is adjustable, so you can make the watermark subtle or prominent depending on your needs.

Will the watermark reduce my photo's quality?

No, the watermark is added as a text overlay; the underlying photo's resolution and quality are otherwise unchanged.

Is my photo uploaded to a server while watermarking?

No, the entire process happens locally in your browser.

Can I remove a watermark from a photo I already downloaded?

No, once exported the watermark is flattened into the image; keep your original unwatermarked file if you may need it again later.
