How to convert more than 1000 of PNG images to JPG formate with black background in photoshop at a time

  • Do your PNG files have transparent backgrounds at present? If so, this is prime for actions, as stated by @utopicam, below. If not, you've got a lot of cutting out to do. – Scott Brown Nov 17 '11 at 16:30

    Also a tool like ImageMagick is a lot faster than photoshop actions. If it's really thousands of images, then this might be worth considering. – bummzack Nov 17 '11 at 16:48

The best thing would be to use Image Processor Pro for Photoshop CS5...(I think you can find it for older versions of photoshop aslo...and you can use it from Bridge witch is nice cause you can see the results faster also...)

Watch how it works in the demo video there. (open link in new tab/window)

Additional info here .

The great thing about it is that it supports Actions also, so first you would create the actions, then use it to automate your process, so you don't have to open each image to Run you Actions, Image Processor Pro does that for you. Good Luck!

The best option is to use photoshop actions. These are a series of steps recorded in Photoshop to generate a certain photo effect (or in general, anything you do in Photoshop). This recorded steps can be saved and play-back at later time to achieve the same effect on different images.

In your case, you would have to record your action when you are putting a black background in one of the images, and stop it after you save it in JPG. Because it's different files you would have to create a batch processing.
