How do I remove watermarks from photos free in Windows 11?

Hi all,

My computer was crashed and all the original images for my own websites are gone. Fortunately, I have most of them uploaded to the website, a blog powered by WordPress. The problem is that all the images are watermarked with my website name and it is done automatically by a WordPress plugin when the photo is uploaded.

I'm curious about what method you would recommend to remove watermarks from photo on Windows 11 PC . Are there software programs that are particularly effective, or any online services you've had good experiences with?

Thank you

    This can be done with a free command line tool LmageMagick, a powerful open-source tool for image manipulation. Here is how to use it to remove watermark from photos on Windows 11:

    Use any image editing tool to identify the coordinates of the watermark, or if the watermark is in a fixed location (like the bottom-right corner), you can define that area explicitly in the command.

    Use the built-in convert or magiick command to remove the watermark from photos. You can achieve this by cropping out the watermark or blending it with surrounding pixels. If the watermark is in a fixed position and you know its coordinates, use the following command:

    magiick input.jpg -crop 0x0+0+0 output.jpg

    This command will crop the image by removing a specified section from the edges, with +0+0 specifying the starting point of the crop area.

    It also supports inpainting (filling in areas based on surrounding pixels). For this, you'll need to create a mask for the watermark area. Create a black-and-white mask where the watermark area is white, and the rest of the image is black.

    magiick input.jpg -region 100x100+200+200 -clamp -fill none -fuzz 30% -draw "color 0,0 floodfill" output.jpg

    This example fills the watermark area with a color or a pattern based on the surrounding image, effectively removing the watermark.
