While there are numerous solutions available to reduce photo file size on iPhone, they all fundamentally work by applying one or more of these core techniques:<\/p>\r\n
- \r\n\t
- Reduce resolution<\/b>: Crop or resize the image dimensions to reduce pixel count. This method maintains the quality of the remaining image area and uses built-in iOS features.<\/li>\r\n\t
- Apply compression<\/b>: Compression works by finding redundant visual information in your pictures and representing it more efficiently. Sometimes, compression can be applied without any visual quality degradation whatsoever (lossless compression), but more space-saving compression settings typically lead to some degree of quality loss. The good news is that most photo compression apps offer a slider or settings to balance file size reduction against visual quality.<\/li>\r\n\t
- Change file format<\/b>: All photos are saved in specific image file formats. Some formats that are still commonly used today are quite old and inefficient (JPEG is a good example), especially when compared with their modern counterparts, such as HEIF (High Efficiency Image Format). However, newer formats like HEIF are not as widely supported, so that\u2019s something you also need to take into consideration.<\/li>\r\n<\/ul>\r\n
These techniques can be applied through your iPhone\u2019s built-in features, but you can also turn to specialized compression apps that provide more options for lowering the quality of the pictures on the iPhone, such as batch processing or precise quality control. The trade-off is that you\u2019ll need to download and potentially pay for these apps, and some may require uploading your photos to external servers.<\/p>\r\n
In the following sections, I\u2019ll start with the simplest built-in iOS solutions that don\u2019t require any additional downloads or setup. Then, I\u2019ll also cover third-party applications and online services so you have more options to choose from based on your needs and technical abilities.<\/p>\r\n
<\/span>Method 1:<\/span> Use iOS Built-In Functionality<\/span><\/h3>\r\n
\n\n\n✅ Pros:<\/b><\/p>
- \n
- Free<\/li>\n
- Privacy-friendly<\/li>\n
- No additional apps needed<\/li>\n
- Built directly into iOS<\/li>\n <\/ul>\n <\/div>\n\n \n
⛔️ Cons:<\/b><\/p>
- \n
- Limited customization options<\/li>\n
- Manual work required<\/li>\n
- Fewer batch processing features<\/li>\n <\/ul>\n <\/div>\n <\/div>\n <\/div>\n \r\n
Crop Photos Using the Photos App\u00a0<\/h4>\r\n
One of the simplest ways to reduce the MB size of photos on your iPhone is by cropping out unnecessary portions, which reduces both resolution and file size by removing pixels you don\u2019t need. The number of pixels you give up is then directly proportional to the size reduction you achieve.<\/p>\r\n
💡 Pro Tip:<\/b> When cropping images using built-in iOS (iPhone) or iPadOS (iPad) features for social media, it helps to be aware of each platform\u2019s \u201csafe zones.<\/a>\u201d For most social platforms, keep critical content within the middle 80% of the frame\u2014particularly for TikTok, Instagram, and Facebook where interface elements often overlay the top and bottom portions of your content. For TikTok specifically (9:16 ratio), avoid placing important elements in the bottom 10% where captions and buttons appear.<\/div>\r\nHere\u2019s how to crop your photos:<\/b><\/p>\r\n
- \r\n\t
- Open the Photos<\/b> app and select the image you want to crop.<\/li>\r\n\t
- Tap the Edit<\/b> button in the top-right corner.<\/li>\r\n\t
- Tap the Crop<\/b> icon at the bottom of the screen.<\/li>\r\n\t
- Drag the corners to remove unwanted portions of the image.
![\"crop](\"\/howto\/wp-content\/uploads\/2026\/08\/crop-photo-on-iphone.jpg\")
<\/li>\r\n\t- Tap Done<\/b> to save your changes (you can go back by opening the same image, tapping the three horizontal dots in the top-right corner and choosing the Revert to Original<\/b> option.<\/li>\r\n<\/ol>\r\n
Since this method uses the built-in Photos app, no extra tools are needed, but you do need to say goodbye to portions of your image. This can alter your photo\u2019s composition, so it works best for images where the main subject doesn\u2019t fill the entire frame. Also, it can be really time-consuming to manually crop multiple images.<\/p>\r\n
Fortunately, there\u2019s another iOS built-in functionality that you can use to shrink photo size on your iPhone with slightly less effort. I\u2019m talking about the Shortcuts app<\/b>, which makes it possible to perform a whole bunch of actions with a single tap on a shortcut you create yourself from scratch or download from someone else.<\/p>\r\n
🔗 A great example is the Reduce Photo File Size shortcut<\/a>. It converts your selected photos to JPEG format with optimized compression settings. This shortcut smartly balances quality and file size reduction, typically shrinking photos by 30-70% depending on their original format and content. It even shows you the before and after file sizes, so you can see exactly how much space you\u2019re saving. The best part is that it can process multiple photos in one go.<\/div>\r\nIf you\u2019d rather create your own shortcut to compress photos on iPhone, then you need to:<\/b><\/p>\r\n
- \r\n\t
- Download the Shortcuts app<\/a> if you don\u2019t already have it.<\/li>\r\n\t
- Open the Shortcuts app and tap the \u201c+\u201d button to create a new shortcut.<\/li>\r\n\t
- Tap Add Action<\/b> and search for Select Photos<\/b>.<\/li>\r\n\t
- Add the Convert Image<\/b> action. In the Convert Image action, tap Show More<\/b> and adjust the quality slider to your preferred level.<\/li>\r\n\t
- Add Save to Photo Album<\/b> as the final action.
![\"make](\"\/howto\/wp-content\/uploads\/2026\/08\/make-shortcut-for-photo-converting.jpg\")
<\/li>\r\n\t- Tap Next<\/b>, give your shortcut a name like Photo Compressor, and tap Done<\/b>.<\/li>\r\n<\/ol>\r\n
I\u2019ve used shortcuts to prepare photos for everything from website uploads to email attachments, each with different quality requirements. However, creating effective shortcuts requires a slight learning curve, and the compression options aren\u2019t as sophisticated as dedicated apps.<\/p>\r\n
Overall, if you don\u2019t feel like learning how Shortcuts work, you can get somewhat similar functionality through the Files app<\/b> and its Quick Actions<\/b> menu. However, this requires moving your images from the Photos app to the Files app first, and then optionally saving them back to Photos afterward.<\/p>\r\n

<\/p>\r\nResize Photos Using the Preview App\u00a0<\/h4>\r\n
If your iPhone is running iOS 26, there\u2019s another built-in way to reduce photo file size – the Preview app. Unlike cropping, resizing lets you keep the entire image while reducing its pixel dimensions, which usually results in a noticeably smaller file.<\/p>\r\n
This is useful when you need a photo for a website upload, attachment, or any other situation where the original resolution is simply higher than necessary.<\/p>\r\n
Note:<\/b> Preview works with images stored in Files. If the photo is currently only in your Photos library, open it in Photos, tap Share<\/b> > Save to Files<\/b>, then open that copy in Preview.<\/div>\r\nHere\u2019s how to resize a photo using Preview:<\/b><\/p>\r\n
- \r\n\t
- Open the photo in the Preview<\/b> app on your iPhone.<\/li>\r\n\t
- Tap the More<\/b> button.<\/li>\r\n\t
- Choose Adjust Size<\/b>.<\/li>\r\n\t
- Enter smaller width and height values, or select one of the available size options.
![\"adjust](\"\/howto\/wp-content\/uploads\/2026\/08\/adjust-size-in-preview-app.jpg\")
<\/li>\r\n\t- Confirm the change and save the resized image.<\/li>\r\n<\/ol>\r\n
The amount of space you save depends on how aggressively you reduce the dimensions. For example, I reduced one photo to 75% of its original dimensions using the percentage option (you can also resize by pixels or inches), and its file size dropped from 19 MB to 8 MB. Dramatically smaller without creating an obvious difference on a phone display.<\/p>\r\n
<\/span>Method 2:<\/span> Use Compression Apps<\/span><\/h3>\r\n
\n\n\n✅ Pros:<\/b><\/p>
- \n
- Batch processing capabilities<\/li>\n
- More control over compression settings<\/li>\n
- Designed for photo optimization<\/li>\n <\/ul>\n <\/div>\n\n \n
⛔️ Cons:<\/b><\/p>
- \n
- Requires downloading additional apps<\/li>\n
- Some may include in-app purchases or subscriptions<\/li>\n <\/ul>\n <\/div>\n <\/div>\n <\/div>\n \r\n
Dedicated photo compression apps outperform built-in iOS features in three major ways:<\/b><\/p>\r\n
- \r\n\t
- They can process multiple photos simultaneously<\/li>\r\n\t
- They offer more precise control over compression quality and resolution<\/li>\r\n\t
- They provide advanced features like format conversion and metadata removal<\/li>\r\n<\/ul>\r\n
Needless to say, not all photo compression apps offer all of these capabilities in one package, so you should familiarize yourself with some of the best options available and pick those that can help you the most. I\u2019ve tested more iOS compression apps than I probably remember, and the following three have earned my recommendation.<\/p>\r\n
💡 Pro Tip<\/b>: For email attachments, prioritize smaller file sizes over perfect quality. With Gmail\u2019s 25MB limit, aim to compress iPhone photos (typically 5-8MB each) down to 1-2MB per image. This allows you to send 10-20 photos in a single email while maintaining good screen-viewing quality.<\/div>\r\nClever Cleaner<\/h4>\r\n
![\"Clever](\"\/howto\/wp-content\/uploads\/2026\/08\/clever-cleaner-main-image.jpg\")
<\/p>\r\n- \r\n\t
- Price<\/b>: Generous free version with no ads\u00a0<\/li>\r\n\t
- App Store rating<\/b>: 4.8 stars out of 5<\/li>\r\n\t
- URL<\/b>: https:\/\/apps.apple.com\/us\/app\/clever-cleaner-ai-cleanup-app\/id1666645584<\/a><\/li>\r\n<\/ul>\r\n
The main thing that makes Clever Cleaner one of the best iPhone cleaner apps<\/a> is its ability to process a huge number of pictures in bulk.<\/p>\r\n
And it can compress not only regular photos in your library, but also videos and Live Photos.<\/p>\r\n
Here\u2019s how you can use it to reduce photo size:<\/b><\/p>\r\n
- \r\n\t
- Download<\/a> and open the Clever Cleaner app from the App Store.<\/li>\r\n\t
- Grant the app permission to access your photos when prompted.<\/li>\r\n\t
- Tap the Compress<\/b> button at the top, then select Photos.
![\"open](\"\/howto\/wp-content\/uploads\/2026\/08\/open-compress-feature-in-clever-cleaner.jpg\")
<\/b><\/li>\r\n\t- You\u2019ll see all your photos displayed with their file sizes.<\/li>\r\n\t
- Select the photos you want to compress (or tap Select All<\/b>).<\/li>\r\n\t
- Tap Compress<\/b> and choose either Optimal<\/b>, Medium<\/b>, or Max<\/b> compression.
\r\n(Medium<\/b> or Max<\/b> works best when you want a noticeable reduction.)![\"compress](\"\/howto\/wp-content\/uploads\/2026\/08\/compress-photo-with-clever-cleaner.jpg\")
<\/li>\r\n\t- Choose whether you want to keep the original or delete it. Just remember that deleted photos are moved to Recently Deleted<\/b>, where they\u2019ll stay for 30 days unless you remove them sooner.<\/li>\r\n<\/ol>\r\n
You can also let Smart cleanup<\/b> automate some of the compression work. Besides cleaning up similar photos, Smart cleanup can reduce the size of screenshots and convert Live Photos. (Clever Cleaner removes the short video portion and turns the Live Photo into a regular still image. That can save quite a bit of space. In my testing, the resulting files were often around three times smaller.)<\/p>\r\n
And if you need to free up even more room, check the Videos<\/b> section. Videos are often some of the largest files in a photo library, so compressing just a few of them can save more space than processing dozens of photos.<\/p>\r\n
Also, Clever Cleaner helps solve a common problem that occurs when making photo files smaller on iPhone \u2013 duplicate photos<\/a>. After compressing photos multiple times, you might end up with several versions of the same picture. The app\u2019s duplicate and similar image finder feature identifies these duplicates and helps you quickly remove them, further freeing up storage space<\/a>.<\/p>\r\n
Finally, there\u2019s a Swipe<\/b> feature for quickly reviewing photos one by one, and it\u2019s completely unlimited in the free version. It can work well as a final pass after compression and duplicate cleanup to help you catch anything that still doesn\u2019t deserve a place in your library. All you have to do is swipe left to delete a photo or right to keep it.\u00a0<\/p>\r\n
💡 Pro Tip<\/b>: Want to go beyond just photos? You can also clean junk files on iPhone<\/a> like cached data, temp files, and old downloads.<\/div>\r\nThe Image Converter<\/h4>\r\n
![\"The](\"\/howto\/wp-content\/uploads\/2026\/08\/the-image-converter.jpg\")
<\/p>\r\n- \r\n\t
- Price<\/b>: Freemium (Pro version starts at $2.99 a month)<\/li>\r\n\t
- App Store rating<\/b>: 4.6 stars out of 5<\/li>\r\n\t
- URL<\/b>: https:\/\/apps.apple.com\/us\/app\/the-image-converter\/id860858310<\/a><\/li>\r\n<\/ul>\r\n
The Image Converter supports an extensive range of file formats \u2013 from common ones like JPG and PNG to more specialized formats like SVG, PSD, and even WEBP.<\/p>\r\n
The workflow is straightforward: select your photo, choose your desired output format, and convert. Most conversions are nearly instant, and you can immediately save, share via AirDrop, or open the converted image in another app. The built-in file browser also lets you access your previously converted files without digging through your photo library.<\/p>\r\n
Just know that some conversions rely on cloud processing and require an internet connection. However, the app now supports local processing for many common conversion types, so not every file needs to be uploaded to a remote server.\u00a0<\/p>\r\n
