Watermark Removal Features

Dual Engine: OpenCV fast processing + AI high-quality repair
Smart Detection: Auto-detect text, logo, translucent and other watermark types
Privacy Protection: All processing is done locally in your browser, no image upload

Select Processing Engine

Watermark Type

Selecting watermark type helps improve auto detection accuracy

Detection Sensitivity (50)

Higher sensitivity detects more watermark areas

Inpainting Algorithm

Telea Algorithm

Based on fast marching method, suitable for most scenarios

Navier-Stokes Algorithm

Based on fluid dynamics, suitable for texture-rich areas

Inpainting Radius (3)

Larger radius repairs wider area but may affect surrounding pixels

Output Format

Select output format for processed images, PNG supports transparency

Output Quality (90%)

Higher quality means larger file size, PNG is lossless and not affected by this setting

Upload Image

Click upload button or drag image file to the upload area

Select Regions

Draw boxes around watermark areas, or use auto detection

Choose Engine

Select OpenCV fast mode or AI high-quality mode as needed

Download Result

After processing, click download button to save the result

This tool provides two image inpainting engines for different scenarios:

OpenCV mode uses classic inpainting algorithms (Telea/Navier-Stokes), fast processing for small watermark areas
AI mode uses MI-GAN deep learning model, supports any resolution, handles complex backgrounds and large watermarks
Auto detection uses edge detection and color analysis to identify potential watermark regions
