Watermark Image

Lay text over an image before you publish it, so that copies stay traceable back to you. Position, size and transparency are adjustable, which is the balance between a mark that is hard to remove and one that does not ruin the picture.

Watermark a photo

Stamp your own text or logo onto an image — entirely in your browser.

How to add a watermark

  1. Open the image you want to mark.
  2. Type the watermark text — a name, a website, or a usage note.
  3. Set its position, size and opacity.
  4. Download the watermarked image.

Frequently asked questions

Where should I place a watermark?
A mark in a quiet corner is tidy but trivially cropped out. One placed across the middle of the subject at low opacity is far harder to remove without damaging the image. Which you want depends on whether you are discouraging casual reuse or deterring deliberate theft.
What opacity works best?
Somewhere around 30 to 50 percent suits most images — clearly legible, but not overwhelming the picture underneath. Lighter marks look better and are easier to remove; heavier marks protect more and intrude more.
Can a watermark be removed?
Be realistic: any visible watermark can be attacked, and modern editing tools are good at it. A watermark raises the effort required and makes unattributed use obvious to viewers. It is a deterrent, not a lock — it does not replace asserting your copyright.
Does watermarking change my original file?
No. The mark is applied to a new image that you download; the file on your device is left exactly as it was.
Is my image uploaded anywhere?
Every step happens inside your browser tab using Canvas and WebAssembly. The file is never uploaded, so there is no server copy to delete and no account to create.
