The Challenge of Changing Pixels on an iPhone

For most people, changing the pixels of their photos on an iPhone can be a daunting task. This is because it’s not a feature that comes as a standard option with the iPhone camera. Additionally, the iPhone’s photo editing tools can be difficult to navigate and sometimes don’t offer the options you’re looking for. In this article, we will share several methods that can help you achieve your desired resolution and make your photos look perfect.

Things You Should Prepare for

Before you start changing the pixels of your photos on your iPhone, here’s a list of things you should prepare for:

Why Can’t I Change The Pixels of My Photo on My iPhone?

There are different reasons why you may not be able to change the pixels of your photo on your iPhone. Here are some of the most common reasons and fixes:

Q1: Why can’t I change the pixels of my photo using the Photos App?
A: The Photos App on your iPhone is limited in features, so it may not allow independent adjustment of resolution and size. Try using other photo editing apps that offer the desired options.

Q2: Why can’t I change the resolution of my photos on my iPhone without changing the size?
A: This is because changing the resolution and size of your photo are directly proportional. So, when you lower the resolution, the size of your photo is also reduced automatically.

Q3: Why can’t I see the Resize option in the Photos App?
A: Depending on the version of iOS on your iPhone, the Resize option may sometimes be hidden under the Aspect Ratio option. Click on the Aspect Ratio option and scroll down to find the Resize option.

Q4: Why do my photos look blurry after changing pixels?
A: When you upscale a photo by increasing the number of pixels, your iPhone tries to recreate the missing pixels, which can result in a blurry image.

Additional Tips

– Always edit a copy of the photo instead of the original copy.
– Always keep the original size of the photo for future reference.
– Don’t overdo the editing. Too much editing can ruin the quality of your photo.
