As a front end developer, there are times where you need to quickly reference a design. At the time of writing this, I had a folder of about 25 .psd files I was sent that I needed smaller more manageable ‘previews’ of. I didn’t want to go through each file and export as a png, or even open up Photoshop at all! So here is what I came up with.
Open up terminal.
We will first need a library called imagemagick. You can download it with the OSX package manager homebrew.
brew update
brew install imagemagick
Once imagemagick is installed, just cd into the directory containing all the .psds and paste this in:
mkdir -p _png; for f in *.psd; do convert ${f}[0] _png/${f}.png; done
Depending on how big the each .psd is, this might take a while. Just let your mac do its thing.
Congratulations! you can now find your new .png files inside currentdirectory/_png/.
To speed up the process later, you can even throw this in an alias!
alias psd2png='mkdir -p _png; for f in *.psd; do convert ${f}[0] _png/${f}.png; done'
