Since youâre dealing with such a large collection of photos, the only logical solution would be to use a tool with batch processing capabilities. Photoshop allows you to do this, but this is a complex program that comes with a certain learning curve. And if you only need to watermark photos, itâs not worth paying the monthly subscription. Another option would be to use a simpler tool that is designed specifically for batch watermarking images. like PhotoMarks. You wonât get the array of features available in complex photo manipulation software, but youâll be able to watermark multiple photos quickly and efficiently.
You may ask me for help for that when needed.
