How to Use
Quick Start
  • Upload images: Drag & drop your photos into the dashed area above, or click to browse.

  • Adjust settings: Use the preview to fine-tune position, size, opacity, and rotation.
  • Download: Click the blue button to save all watermarked images as a ZIP file.
Notes
  • File limit: Due to browser memory constraints, keep batch sizes within these guidelines:
    • Desktop: 50–100 images
    • Mobile: 10–30 images
  • Processing time: Large images may take a moment to process after clicking the download button.
  • Privacy: All processing happens entirely in your browser. Your images are never sent to any server.
Frequently Asked Questions
Q. Does adding a watermark reduce image quality?
A. The watermark is composited directly over your original image, so there is virtually no visible quality loss. The original resolution is preserved even after adjusting opacity or position.
Q. Can I use a transparent PNG logo as the watermark?
A. Yes. In “Image” mode you can select a transparent PNG logo and it will be overlaid cleanly with its transparency intact. Size and margin are fully adjustable.
Q. How many images can I process at once?
A. It depends on your browser’s memory, but a good guideline is 50–100 images on desktop and 10–30 on mobile. For larger batches, process them in smaller groups.
Q. Are my uploaded images sent to a server?
A. No. Everything — loading, watermarking, and ZIP export — runs entirely in your browser, so your images never leave your device.
