When batch editing photos, you can export, enhance, crop, straighten, rotate, and apply color adjustments to multiple images at a time. You can start with some of the included workflows and adjust them or create custom batch editing workflows of your own.
There are many uses of the batch feature in Pixelmator Photo. For instance, you can edit multiple images at a time using the crop ratios or color adjustments that you create in Pixelmator Photo yourself. To do that, you first create a custom crop preset or color adjustment preset, then, use this preset to create a new workflow or update an existing one.
