Launch the Photos app on an iPhone or iPad running iOS 15, then select a photo in your library that contains text in a language that you want to translate.Note that by using largely the same procedure as described below, you can also translate text whenever it appears in the viewfinders of Apple's stock Camera app.
The following steps show you how it's done in the Photos app. Now, in iOS 15 and iPadOS 15, translation has gone systemwide, which means you can take advantage of Apple's new Live Text feature to translate other languages that appear in your photos.
Apple entered the translation game in iOS 14 with native Safari browser translation and a dedicated translation app.
