Instructions:

Features:

  • Pure front-end processing, images are not uploaded to the server, ensuring privacy and security
  • Supports custom watermark text, color, opacity, size, and spacing
  • Watermark automatically tiles to cover the entire image, preventing cropping
  • Adjustable rotation angle for diagonal watermark effects
  • Real-time preview, what you see is what you get

Use Cases:

  • Add "For XX Use Only" watermark to ID cards, passports, and other documents to prevent misuse
  • Add confidential labels to contracts and financial reports
  • Add brand or copyright information to product images

Tips:It is recommended to use low opacity (10%-30%) and moderate font size to provide protection without affecting image recognition. Smaller watermark spacing improves protection but may reduce image clarity.
