About the Add a Watermark to an Image

A watermark deters casual reuse and makes the source obvious when an image is shared. It is not protection: anyone determined can crop it out or paint over it.

A corner watermark is easy to crop away; a centred or tiled one is harder to remove but competes with the image. Which trade-off is right depends on whether you are labelling or defending.

Questions people ask

Is my image uploaded anywhere?

No. The image is decoded, processed and re-encoded by your own browser using the canvas API. You can watch the network panel while it runs, or disconnect from the internet after the page loads - the tool keeps working.

Does a watermark prove copyright?

No. Copyright exists from the moment a work is created. A watermark makes authorship visible and removal deliberate, which can matter in a dispute, but it is evidence rather than protection.

Is your image uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your image never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
