How to Use Add Watermark to Image

  1. Upload an image — JPG, PNG, WebP up to 500 MB.

  3. Download the watermarked image — PrivaTools overlays the text at the chosen position with the chosen opacity. Original is unchanged.

Frequently Asked Questions

Can I watermark with an image instead of text?

Currently text-only watermarks. Image watermarks (logo overlay) are on the roadmap.

Is the watermark removable?

Depends on placement. Watermarks over high-detail areas are harder to remove than over solid backgrounds. AI inpainting tools can sometimes erase them — for stronger protection, use diagonal repeating patterns.

Does it affect image quality?

Negligibly. Output is at the same JPEG quality as input.
