It is likely that on more than one occasion you have found yourself needing change photo resolution on iphone to be able to include it in a document, share it by email, publish it on your favorite social network… Although Apple does not natively allow us to edit the resolution of images via the Photos application, it offers us a tool to be able to do this.
I’m talking about the Shortcuts app, an app that Apple introduced to iOS a few years ago after acquiring the company behind Workflow and is also available for macOS Monterey. With this app we can create custom workflows to automate tasks of all kinds and among which is the possibility of modifying the resolution of the photos of our iPhone.
If you find the Shortcuts app somewhat complex, no problem, since you can use any of the different applications available on the App Store to be able to perform this task, or even use Apple’s Mail application, although with the latter it does not allow us to adjust the images to the resolution we are looking for.
With the Shortcuts app
Once again, with the Shortcuts application, we have at our disposal one of the fastest and easiest methods to change image resolution stored on our device.
There are many shortcuts to change image resolution on the internet, however, the one you can download from this link, is one of the most complete, because it allows us to establish if we want to modify the width or the height of the image and not only the height as most do.
How to use the shortcut
- To use this keyboard, the first thing you need to do is access the Photos app and select the image to which we want to change the resolution.
- Then we click on the button To share and select the shortcut Resize image.
- Then the application will inform us of the size in pixels of the image that we have selected and invites us to press Ok to continue. This message is merely informative, so we know the original size of the image and proceed accordingly.
- In the next window we are prompted:
- Modify the height and width without respecting the proportion.
- Modify the height while respecting the proportionality.
- Modify the width while respecting the proportionality.
- Change the size based on a percentage.
- In the images that accompany these lines, I have selected change image width so that it goes from 1536 to 900. Once we have entered the new size, whether it is larger or smaller than the current one, we click on Ok.
- Finally, the request will prompt us to delete the original image or keep it when with the one we just modified.
This Siri Shortcut, supports batch processes, although if we use images of different formats, the conversion can be a bit cumbersome.
With the Mail app
The easiest and fastest way to lower image resolution without using shortcuts or third-party applications through the Mail application. When we share large images through Mail, the application will ask us if we want to send the content in its original resolution or if we want to reduce the size of the images .
The problem with this option is that it does not show us the final resolution of the images. However, if this is not a problem, since our idea is to scale down the original image, then mailing the images via Mail is a fantastic option to consider.
With third-party apps
Unless you need to reduce or enlarge the resolution of all the photos you take with your iPhone, in this compilation of applications I only show you free or free apps with ads, ads that can be removed using an in-app purchase.
At the time of publishing this article, none of these apps include a monthly or yearly subscription to be able to use it. I decided not to include this type of application, because if you usually change the resolution of the photos you take, it is very likely that you are doing this process from a PC or Mac, so paying a subscription does not not really worth it.
