How to Compress Photos on Your iPhone or iPad

iPhone cameras are evolving quickly, and managing storage space and data usage on your iPhone is becoming crucial. Compressing photos on your iPhone can come in handy in many ways, for example dealing with low storage space on your iPhone, uploading photos to a website with an upload size limit, or uploading multiple photos without wasting data. Although there is no native app available on the iPhone for compressing photos, several workarounds allow you to do this. In this article, we discuss five different ways you can compress photos on the go.

You can compress photos on your iPhone by installing third-party apps. These apps allow you to select multiple images for compression and set the quality and dimensions of the compressed images. You can also compress photos using online applications by uploading your images on their website and downloading a compressed version. If you want to compress photos using already installed applications, share the photos through Email, Messenger or WhatsApp and download the compressed versions. Another easy trick for compressing photos is to take a screenshot of the photos.

Storage space is crucial for iPhone users, making its efficient management necessary. High-quality images captured by the iPhone camera are several MBs in size and can take up a lot of space on your iPhone. Uploading these images can also become a challenge as many websites and email clients have upload size limits. Data usage concerns are another reason to compress photos on your iPhone.

There are a few ways you can compress photos on your iPhone. You can find one from the list given below that best fits your needs.

1. Third-Party Apps

Apple doesn’t provide a built-in app for photo compression, but a few third-party apps available on the App Store allow you to compress photos on your iPhone. These apps provide a fast, convenient, and flexible interface for compressing your photos.

According to App Store ratings, listed down are two of the best third-party apps for photo compression. I have given a quick comparison chart of the two apps.:

Ads Free: Yes, Pro: No Free: Yes, Pro: No
Rating 4.7⭐ (8.1k User Ratings), 4.5⭐ (2.1k User Ratings)

These apps allow you to choose image quality and size for the compressed photos, thus giving you complete control over the result. Compared to all the other alternatives, third-party apps offer you the most flexible solution for compressing your photos.

Several online applications allow you to compress your photos without having to install a third-party app. These applications are also straightforward to use.

3. Email

As opposed to the more sophisticated methods given above, there are a few quick tricks you can use to compress photos on your iPhone. Although these hacks get the job done, they do not offer you the flexibility to select the image size or dimensions.

An easy hack to compress photos on your iPhone involves using the Email app on your iPhone. Again, this is one of the easiest options without any third-party apps or online applications.

The step-by-step guide is:

  1. Open the Photos app on your iPhone.
  2. Select the photos you want to compress.

4. Messenger/WhatsApp

You can compress photos on your iPhone by sending them to yourself through WhatsApp or Messenger, as these chat apps compress photos shared through them. Although I am only mentioning these two apps, other chat apps often use similar principles.

The quick steps for this trick are:

  1. First, open your iPhone’s Photos app.
  2. Select the photos you need to compress and tap the Share option.

  6. Now open the photos in the chat window and download them.
  7. Find the compressed version of the photos in your Library.
  8. Keep or delete the original photos from your Library.

5. Take Screenshots

The simplest trick for compressing photos on your iPhone is to take a screenshot of the photo after opening it in the library.

In case you have not used the screenshot feature on your iPhone before:

  1. Open the Photos app.
  2. Open the photo you need to compress.
  3. Press the power and volume up button together.
  4. Quickly release the two buttons.
  5. You will see a thumbnail temporarily appear in the left corner of your screen.
  6. Click on the thumbnail to see the Screenshot.

HEIF Format on Your iPhone

In the above sections, I provided you with a comprehensive guide on compressing photos on your iPhone. However, if you are trying to compress photos on your iPhone due to space issues, you might wonder how you can avoid running into this problem in the future.

You can save a lot of space on your phone by using the HEIF format for your photos. This format allows you to save your photos without having to compromise on the image quality.

By selecting this format, you will reduce your image sizes by up to a half, compared to the JPEG format.

To select this format:

  1. Navigate to your iPhone’s Settings.
  2. Scroll down to and select the Camera option.
  3. Select the Formats option.

There are several ways you can compress photos on your iPhone, as outlined in this guide. However, one thing to keep in mind is that we are compromising on the image quality whenever we compress photos. Therefore, if you need to print your photos or display them on a high-resolution screen, you should upload your images on file-sharing applications to share them, such as iCloud or Google Drive.
