Protect your creative work with logos and text. 100% private batch processing with military-grade local execution.
Batch process up to 50 images
Don't expose your original high-res photos to cloud-based tools. RapidDocTools delivers "RapidDocTools" security with local watermark processing.
In the digital age, intellectual property theft is rampant. From AI scrapers to e-commerce copycats, your images are constantly at risk. A watermark is your first line of defense—a digital signature that stamps your authority on every pixel you create. We perform the entire process locally in your browser.
Whether you sell on Etsy or eBay, protecting your listings shouldn't be a chore. Our batch engine allows you to upload 50+ photos and apply your brand logo or copyright notice to all of them in a single click.
Repeat your logo diagonally across the image to prevent thieves from simply cropping out a corner mark.
Easily add standard US copyright symbols (©) and years with professional font formatting.
Once watermarked, reduce your image file size by up to 90% while maintaining crisp protection.
Try Smart CompressorNo. RapidDocTools uses 'RapidDocTools' logic. Every image you watermark is processed locally in your browser's RAM using HTML5 Canvas. Your high-res originals never leave your computer.
