![[iOS] How to batch crop multiple photos to a specific ratio such as 4:3](img/ogp.png)
Here's how to batch crop multiple photos to a specific ratio, such as 4:3, using iOS Shortcuts.
While we'll focus on the 4:3 ratio, you can also crop to other ratios like 16:9, and I'll show you how to do that as well.
First, install the Shortcuts app.
We also introduce a shortcut recipe for cropping multiple photos into a square, so please take a look if you like.

The common photo development size is 4:3, but if you usually take photos with your iPhone in 16:9 or square (square) format, this will be useful when you want to batch crop many photos to 4:3!
How to crop to a specific ratio like 16:9
To crop to a specific ratio like 16:9, please modify parts of the recipe.
In the recipe, you'll find the number "1.333" in several places, and

the number "0.75" also appears.

These are the two values needed when cropping to a 4:3 ratio:
"4 ÷ 3 = 1.333..." and
"3 ÷ 4 = 0.75".
So, for example, if you want to crop to 16:9,
change "1.333" to "1.777" and
"0.75" to "0.563".
Additionally, if you want to crop to 3:2, for example,
change "1.333" to "1.5" and
"0.75" to "0.666" to crop to 3:2.
While these calculations could be incorporated into the shortcut recipe, I've opted for manual input to keep the recipe as simple as possible.
