Add Watermark to Image

To watermark a photo, add it, type your name, site address or copyright line, choose a corner, centred or tiled position and set the size and opacity. The text is drawn into a new copy with a soft shadow so it stays readable; your original is untouched and never uploaded. A tiled mark is the hardest to remove.

How to use Add Watermark to Image

  1. 1Add the picture.
  2. 2Type the wording — a name, a site address or a copyright line.
  3. 3Choose a position, then set the size and opacity.
  4. 4Download the marked picture; the original is untouched.

How it works

The text is drawn into the picture itself at a size proportional to its width, so the same settings look right on a small web photo and a full-resolution camera file. A soft shadow sits behind the text, which is what keeps white lettering readable over a pale sky.

Position is a trade-off rather than a preference. A corner mark is unobtrusive and trivially cropped off. A tiled mark across the whole frame is far harder to remove and equally hard to look past. Centred sits between the two.

Be clear about what this achieves: a watermark discourages casual reuse and identifies the source when a picture travels. It is not protection, because anyone with an editor and patience can paint it out.

Images are decoded by the browser, redrawn on a canvas and re-encoded on your own machine. Nothing is uploaded, so there is no waiting on a queue and no copy of your photos anywhere else.

Tips and common mistakes

  • Tile the watermark when the goal is to discourage reuse; a corner mark is cropped off in seconds.
  • Keep the opacity low enough that the photo is still enjoyable to look at.
  • Put a single mark over a busy part of the picture rather than a plain corner, where it is easiest to remove.
  • Keep an unmarked original for your own archive and for printing.

Frequently asked questions

Can the watermark be removed?
By someone determined, yes. Tiling it across the picture makes that much more work than a single corner mark.
Can I use my logo instead of text?
This version places text. A logo overlay is a sensible future addition.
Does it change the original file?
No. A new picture is produced and the file on your device is untouched.
Which colour works best?
White with the built-in shadow reads on most photographs. Black suits pale, high-key pictures better.
What wording should I use?
Your name or business name, your website address, or a copyright line such as © 2026 Your Name. Short wording reads best.
Does the text scale with the picture?
Yes. Its size is set in proportion to the picture's width, so the same settings look right on a small web image and a full-size camera file.
Is my photo uploaded?
No. The watermark is drawn in your browser.
