📖 Description

1. Why Do You Need to Add Watermarks to Images?

In the internet age where content is publicly disseminated, protecting image copyright is crucial:

Prevent Unauthorized Use: Adding watermarks to photography, design sketches, or product photos effectively reduces the risk of direct theft by others.
Strengthen Brand Recognition: Embedding a company logo in the corner of promotional images can increase brand exposure and enhance a professional image.
Information Labeling and Traceability: Adding labels such as "For Reference Only," "Strictly Confidential," or employee names to internal documents facilitates document management and accountability tracking.
Prevent Unauthorized Reposting on Social Media: Adding unique personalized identifiers to self-media images helps establish a personal creative style.

2. Core Feature Analysis

This site's tool provides a fully automated and customizable operation experience, ensuring perfect integration of the watermark with the original image:

A. Two Watermark Modes

Text Watermark: Supports custom text input (e.g., name, URL, date) and allows free adjustment of font, size, color, and transparency.
Logo Image Watermark: Supports uploading transparent PNG icons as watermarks, suitable for placing corporate logos or personal design signatures.

B. Intelligent Layout and Positioning

Nine-Grid Quick Positioning: One-click placement of the watermark in nine classic positions on the image, such as top-left, center, and bottom-right.
Full-Screen Tiling (Tile Mode): Supports tiling the watermark across the entire image with adjustable spacing. This is the most defensive method against image theft.
Angle Rotation: Watermarks support 0-360 degree rotation. Diagonal layouts are more stylish and harder to remove.

C. Visual Integration Control

Transparency Adjustment: Freely set the watermark's opacity, ensuring clear copyright identification without overly obscuring the main subject of the image.
Layer Blending: Optimized algorithms ensure the watermark maintains good visibility against both dark and light backgrounds.

D. Privacy and Batch Processing

Local Processing: The watermark synthesis process is completed locally in the browser. Images do not need to be uploaded to a server, ensuring absolute security even when processing sensitive documents like ID photos.
Batch Watermarking: Supports uploading multiple images at once and applying the same watermark configuration with one click.
