Professional Watermarking Features
Everything you need to protect your photography and digital assets, directly in your browser.
Smart Auto-Scaling
Watermarks automatically adapt their size dynamically whether the photo is a tiny 800px web image or a massive 4K raw photograph. Perfectly consistent across your entire batch.
100% Private (No Uploads)
Your high-resolution photos are processed completely within your browser. We have zero servers and do not collect your photos.
Tiled Pattern Mode
Repeat your watermark diagonally across the entire photo to protect against AI object removal and manual cropping.
Image & Logo Support
Use standard text with custom styling, or upload a transparent PNG image to use your official company logo as a watermark stamp.
One-Click ZIP Export
Don't download them one by one. Our tool packages all watermarked and compressed images into a single ZIP for easy organizing.
Live Batch Preview
Don't guess how it looks. Use the carousel arrows to instantly preview your watermark setting across every single photo in the batch before downloading.
Granular Position Controls
Use the 9-point anchor grid (Top-Left, Center, Bottom-Right) and adjust edge padding margin for pixel-perfect placement.
Drop Shadows & Strokes
Ensure your watermark text is legible against both bright skies and dark shadows with contrasting drop shadows and opacity controls.
Frequently Asked Questions
Are my images uploaded to any server?
No! DevLuxe Batch Watermarker processes every image locally inside your web browser. Your photos never leave your device, ensuring complete privacy.
What is 'Smart Auto-Scaling'?
Unlike basic tools where a watermark looks huge on a small photo and tiny on a 4K photo, our tool dynamically scales the watermark relative to each individual image's dimensions so it looks perfectly consistent.
Can I use a transparent PNG as a logo?
Yes. Simply switch the Watermark Mode to 'Logo Mode' and upload your transparent PNG file to be used as the stamp.
Is there a limit to how many images I can process?
Because processing happens in your browser, the limit depends entirely on your device's RAM. Most modern computers can comfortably handle batches of 50-100 images at once.
Does this tool strip EXIF data?
Yes. Because new images are generated via the HTML5 Canvas, the original EXIF data (like GPS location or camera settings) is naturally stripped during the process.
