If you’re like most people, your hard drive is bursting at the seams with Photoshop files. But don’t worry, there’s a way to compress them without losing any quality. To start, open the file you want to compress and select all of the layers. Next, go to File > Compress > Deflate. Photoshop will start compressing the file and will give you a warning that it may lose some quality. If you’re happy with the results, click OK. If you’d like to restore some of the lost quality, go back to File > Compress > Deflate and choose Lossless from the options menu. This will create a smaller file but with better quality than if you had compressed without lossless compression first. ..
