The Free Watermark Tool by Nano Banana helps you add watermarks to images for copyright protection and branding. Whether you need text watermarks with your name/brand or logo watermarks with your company mark, our tool makes it easy. Customize opacity for subtle or prominent watermarks, adjust position (corner, center, tiled), control size and rotation. Perfect for photographers protecting their work, businesses branding product images, content creators securing their visuals, and anyone wanting copyright protection. Ironically, our watermark tool adds NO watermarks to YOUR watermarked images—completely free!
Add text watermarks with custom fonts or upload your logo/signature as image watermark.
Adjust opacity, position, size, rotation, and color. Complete creative control.
Corner, center, or tiled across entire image. Drag to position precisely.
Apply same watermark to multiple images at once. Protect entire albums.
We don't add OUR watermark to YOUR watermarked images. Truly free.
Your images and watermarks stay on your device. Never uploaded.
Click to upload or drag your photo that needs watermarking. Supports PNG, JPG, JPEG, and WebP up to 10MB.
Choose text or logo watermark. Enter your text or upload logo. Adjust opacity (10-100%), position (corners, center, tiled), size, rotation, and font (for text). Preview in real-time.

Add custom text watermarks. Choose fonts, adjust size, color, and outline. Perfect for copyright notices, names, or URLs.

Control transparency from 10% (subtle) to 100% (solid). Balance protection with image aesthetics.

Use the same watermark style across your portfolio for brand recognition.

Photographer
“Finally a free tool that doesn't watermark my watermarked photos! Perfect for client proofs.”
Digital Artist
“The diagonal tiled watermark protects my art from theft while still showcasing it.”
Stock Photographer
“Batch watermarking saves me hours. Essential for my stock photography workflow.”
Our tool embeds watermarks permanently into images. While tech-savvy users might remove simple watermarks, positioning strategically and using appropriate opacity makes removal difficult.
