What is Bulk Image Watermark?
This tool lets you add a watermark to multiple images at once, whether you're protecting a photography portfolio or branding product photos for a store. Instead of opening each photo individually, you can batch watermark photos with a consistent logo, text, or signature in a single pass. It's designed for photographers, small business owners, and content creators who need to watermark photos in bulk.
How It Works
Each image is loaded into the browser and drawn onto an HTML5 Canvas, where your chosen text or logo image is layered on top at the position, size, and opacity you set. The tool repeats this process automatically for every file in your batch, applying the exact same watermark settings so your branding stays consistent. Once each canvas is composited, the result is exported as a new image file.
Is It Safe to Use?
Your photos and watermark design are processed entirely inside your browser tab using the Canvas API, so nothing is uploaded to an external server. This keeps unreleased product photography, client galleries, or personal photo collections fully private during the entire watermarking process. No files are stored anywhere once you close the page.
