Add a text or image watermark

Free, private, in-browser image watermarking — nothing leaves your device. Add custom text or choose a logo, then control its position, size, color, and opacity before downloading.

How watermarking works here

Add text or your own logo over an image, then set its position, size, and opacity. Your browser composites the watermark onto a new copy of the picture and hands it back to download — all locally, with nothing uploaded and your original left untouched.

When to add a watermark

  • Protect your work: mark photos before sharing them publicly.
  • Brand your images: add a logo or name to product shots and social posts.
  • Label proofs: stamp “DRAFT” or “PROOF” on previews you send for review.
  • Claim attribution: add a credit line to portfolio or press images.

Tips for an effective watermark

A watermark works best when it's semi-transparent — visible enough to deter reuse, but light enough not to ruin the image. Placing it across an important part of the picture (not just tucked in a corner) makes it harder to crop out. Keep the same style across your images for consistent branding. A text watermark is quickest for a name or copyright line, while an image watermark lets you place your actual logo — save the result as a PNG if the mark needs a transparent edge.

Frequently asked questions

Are my images uploaded to a server?

No. Watermarking happens entirely in your browser, so your images never leave your device.

Can I use my own logo as the watermark?

Yes. Add text, or overlay your own logo image.

Can a watermark be removed?

It deters casual copying, but no visible watermark is completely tamper-proof. Placing it over key areas at moderate opacity makes removal harder.

Can I watermark several images at once?

Yes. Apply the same watermark across a batch and download them together.

Is there a size limit?

No fixed cap — larger images use more of your device's memory.
