Add Image Watermark To Image using n8n action

PDF4me Add Image Watermark To Image adds custom image watermarks to images through n8n automation workflows. Process images via n8n triggers, binary data, base64 strings, or public URLs to overlay watermark images (logos, stamps, signatures) with customizable positioning (corners, center, diagonal, custom coordinates), transparency control, sizing options, and offset adjustments. This solution is ideal for image branding, copyright protection, logo overlays, security watermarking, batch image processing, and automated watermark workflows that require professional image composition with flexible positioning and seamless integration.
