How to create an image conversion folder in macOS

In macOS, you can easily convert images in bulk using the Preview app on your system. However, if you are constantly working forcing you to convert images, you can create a folder action that can get the job done quickly and easily.

This guide will show you a step by step process on how to do this. For this, we will use Folder Action which will automatically convert the images dropped in the folder to the desired extension. This too without needing to open the image in any application.

Guide to Create Auto Image Conversion Folder on Your Mac

Step 1: Open the "Automator" application on your system. You can do this by going to the Applications folder or from the launcher. You can also press Command + Spacebar and type Automator in Spotlight Search to open the app.

Step 2: When the application opens, select the "New Document" button in the upper left corner.mac-folder-action-image-format-1

Step 3: It will now ask you to choose the type of document. In the given options, click on "Action on the folder" then on "Choose" in the lower right corner.

Step 4: At the top of the workflow area, click the drop-down list next to "Folder action receives files and folders added to:" then select "Other ...".


Step 5: Now select the folder you want to assign the image conversion process to.

Step 6: In the Library option in the far left sidebar, select “Photos”.

Step 7: In the Actions column, drag "Change Image Type" to the workflow area on the right side.


Step 8: You will now be asked if you want your action to convert copies of images placed in the folder and preserve the originals, select "Add". If you want to convert the original images, select "Do not add".


Step 9: In the Change Image Type action panel, choose the type of format you want to convert the images to. Here we select JPG.


Step 10: Now, from the menu bar, select File> Save… or press Command + S. Name the file action as you see fit, then click “Save”.

That's all. Now whenever you want to convert an image to JPG format, just drag and drop the file into this folder and the process will be done automatically. You can also do the same using other actions, such as “Quick action” and “Applications”. More information on this will be covered in future guides.
