Watermark Image — Text & Logo Editor

How to Add Watermark to Images Online

Protect your photos and artwork by adding a visible watermark using our free browser-based image editor. Unlike simple watermark tools that only let you place text in one of four corners, AIAZHTools gives you a full design editor where you can drag, resize, rotate, and style your watermark exactly where you want it. Add text watermarks with custom fonts, colors, stroke, shadows, and opacity — or upload a logo image as a watermark.

The editor supports both text and image watermarks simultaneously. For text watermarks, choose from dozens of font families, adjust font size, color, bold, italic, underline, letter spacing, stroke width, and shadow effects. For logo watermarks, upload any PNG, JPG, or SVG file and control its opacity, scale, rotation, and position on the canvas. Both types of watermarks can be layered, reordered, and fine-tuned with real-time preview.

All image processing happens entirely in your browser using the Fabric.js canvas engine. Your images are never uploaded to any server, ensuring complete privacy and security. Download your watermarked image as a high-quality PNG or JPEG file with no compression artifacts, watermarks from us, or registration required. Perfect for photographers, designers, content creators, and businesses who need to protect their visual content.
