Add Watermark to Image Online

Watermark images online with text or a logo. Free, private, fully in your browser. No upload.

Need batch processing? Download Compresso for unlimited compressions.

Add a watermark to an image online for free. Overlay text or a logo on JPG, PNG, or WebP to protect proofs, portfolio samples, and social previews. This watermark tool runs fully in your browser on Compresso. Nothing is uploaded.

Photographers watermark client previews; artists protect WIP posts; agencies stamp drafts sent for feedback. A visible watermark discourages unauthorized reuse while keeping the underlying image recognizable.

Processing stays private on your device. Need smaller files after watermarking? Use our Compress JPG or Compress PNG tools, or download Compresso for offline bulk compression on Mac and Windows.
