Image Watermarker (Text, Batch, Copyright)
Batch watermark photos without uploads or watermarks of our own. Ideal for sellers, creators, and teams protecting assets.
Add text watermarks to batches of images and export as JPG/PNG ZIP.
A high-volume, batch-processing watermarking utility engineered for creators and agencies. Instantly stamp text, copyright notices, or brand vectors across up to 40 images simultaneously. Fine-tune opacity, positioning, and typography with a live canvas preview, then export a pristine ZIP file entirely offline, guaranteeing your unreleased assets never touch a cloud server.

The Theft of Digital Assets
In the era of massive AI scraping and relentless social media content theft, artists, photographers, and e-commerce sellers must protect their visual IP before it hits the internet. A highly visible, beautifully integrated watermark acts as a critical deterrent against unauthorized redistribution.
Frictionless Batch Processing
Manually dragging a text layer across 40 different product photos in Photoshop is an agonizing waste of hours. Our Image Watermarker solves this by generating an instant batch-processing pipeline. Drop an entire folder of high-resolution images into the browser, dial in your custom typography, adjust the alpha-channel opacity to ensure the watermark blends perfectly without destroying the photo, and hit process.
Cryptographic-Level Asset Security
This tool uses HTML5 Canvas to render watermarks in your browser. Images are not uploaded to JW Tool Box; the site separately collects usage information as described in the Privacy Policy. Check the terms and data practices of any service before uploading confidential assets.

- Privacy by default: No uploads—images are processed in your browser and downloaded as a ZIP.
