I have thousands of psd files to save as png. The psd files are not different, except for a small text in the center of a image. Is there a way to automate the job?
Yes. Open your actions window. Create new action. Record yourself opening, saving the file as png and closing the file.
Then under File -> Automate -> Batch. Point it to your psd folder and select your action. It should run through the files saving them as pngs.
A quick google search may help if you're new to actions.
