Super easy way to put or watermark on a photo in bulk?

You can use FF mpeg because it is an open-source multimedia framework that also supports image watermarking.

As a versatile command-line tool, it can be used to add a watermark to existing photos and allows for precise control over the positioning of text and image overlays.

How to Add a Watermark to Existing Photos

1. Install the software on your system

2. Open a Command Prompt in the folder containing the photos.

3. Text watermark:

for %f in (*.jpg) do ff mpeg -i “%f” -vf “drawtext=text=‘Your watermark’:fontcolor=white@0.3:fontsize=36:x=20:y=20” “watermarked_%f”

4. Image watermark:

for %f in (*.jpg) do ff mpeg -i “%f” -i logo.png -filter_complex “overlay=W-w-20:H-h-20” “watermarked_%f”

The software has no restrictions. The batch processing feature allows you to efficiently add watermarks to large numbers of images, though the command-line interface requires users to be familiar with its syntax and parameters.
