How To Make Your iPhone Pictures a Smaller File Size By Default

There are several reasons you might want to resize your photos. Maybe you’re running out of storage space on your device and need to free up some room. Or maybe you need to send a photo via email or a messaging app, and it’s too large to attach.

How To Make Your iPhone Pictures a Smaller File Size By Default

Sometimes, you might even need to resize an image to upload it to a specific site. Regardless of the reason, changing an image’s file size is relatively easy to do.

This article will outline the different ways of reducing the size of your photos on your iPhone.

How to Take Photos With a Smaller File Size on an iPhone

When it comes to iPhone photography, we’ve come a long way in a short amount of time. The cameras have gotten better and better, allowing us to take some truly amazing photos.

As the quality of our images has increased, so has the file size. A single picture can now take 1.5 to 5 MB of space, which can quickly add up if you’re an avid photographer.

There is no easy way to resize photos on an iPhone or iPad without losing quality. But there are a few workarounds that can help make iPhone pictures a smaller file size without sacrificing too much quality.

Change the File Format of Your Photos

When it comes to pictures and videos, we all want to be able to capture high-quality images and footage. What many people don’t realize is that the format of the files can make a big difference in terms of file size.

By default, your iPhone saves photos with the .jpg extension. While JPG is a great format for most photos, it’s not always the best choice for file size. If you want to take photos with a smaller file size, try changing the format to PNG or HEIF.

To do this, follow these easy steps.

  1. Go to Settings > Camera > Formats.
  2. Select your desired format.

Keep in mind that not all formats are compatible with all devices, so you may want to stick with JPG if you plan on sharing your photos with others.

Adjust the Photo Resolution

The resolution of a photo is the number of pixels (or dots) that make up the image. The higher the resolution, the sharper and clearer the photo will be. But did you know that you can adjust the resolution of your photos?

By lowering the resolution, you can reduce the file size of your photos. To change the resolution of your photos, take these steps.

  1. Go to Settings > Camera > Record Video.
  2. Select “720p HD at 30 fps” , “1080p HD at 30 fps” , “1080 HD at 60 fps” and “4k at 30 fps.” adjusting from there based on your needs.

Use the High-Efficiency Image Container (HEIC) Setting in the Camera App

If you have iOS 11 or later, you can take advantage of the new High Efficiency setting in the Camera app. This setting uses a new compression method that results in smaller photo file sizes without sacrificing quality.

Take these steps to turn on this setting.

  1. Open the Camera app.
  2. Navigate to Settings > Format > High Efficiency.

Once HEIC is enabled, any new photos you take will be saved in this new format – reducing their file size while still keeping their original quality intact.

If you ever need to send a photo to someone who doesn’t have an iPhone or other device that can view HEIC files, simply open the photo in the Photos app and tap Share > Duplicate > Duplicate as JPEG.

How to Reduce the File Size of Existing Pictures on an iPhone

Have you ever taken a picture with your iPhone, only to realize later that it’s too large to send via email or text? Or maybe you want to save some storage space on your phone by reducing the file size of some of your existing photos. Either way, reducing the file size of a photo on your iPhone is easy.

Here are a few tools that can help.

Online Compressors Like TinyWow

If you don’t want to download another app to your already overflowing home screen, you can also use an online compressor like TinyWow. Simply head over to their website, upload the photos you want to compress and wait for the compression to happen.

Once it’s finished, you can download the compressed photos to your iPhone or save them directly to your Dropbox or iCloud account.

Compression Apps

There are a number of apps available that will allow you to compress the file size of your photos without losing any quality. One of the most popular apps is Image Size, which is available for free in the App Store.

Once you’ve downloaded and installed the app, simply open it up and select the photos you want to compress. The app will then do its magic and reduce the file size of your photos so they take up less space on your camera roll.


This one is a bit more time-consuming than the first two options, but it’s worth it if you’re tight on storage space. When you crop a photo, you’re essentially removing parts of the picture that aren’t essential to the main subject. For example, if you have a picture of yourself in front of the Eiffel Tower, you might crop out the sky or the ground so the focus is solely on you and the tower.

To crop a photo on your iPhone, follow these easy steps.

  1. Open the Photos app and select the picture you want to edit.
  2. Tap “Edit” in the top-right corner and select “Crop.” From there, you can choose how much of the photo you want to keep and how much you want to crop out.
  3. Once you’re happy with your selection, tap “Done” in the top-right corner and voila! You now have a cropped photo that takes up less space on your camera roll.

Maximize Your iPhone’s Storage Space

Your iPhone’s camera roll is probably full of pictures that take up too much storage space. But deleting those memories is not an option. Fortunately, there are a few ways of reducing the file size of existing pictures on your iPhone so you can free up some space without having to delete any treasured memories.

You may use a compressing tool like Image Size or TinyWow, or crop unwanted parts out of your photos to make iPhone pictures a smaller file size. Alternatively, you can tweak your iPhone’s camera settings and select a lower resolution or a format that reduces the size of your photos.

Give one (or all) of these methods a try next time you’re running low on storage space.
