There are multiple ways to compress videos on iPhone, and the right approach depends on what you\u2019re trying to do and where the video needs to go:<\/p>\r\n
- \r\n\t
- Just need a quick fix for messaging or email?<\/b> A third-party app to compress video<\/a> will get the job done in seconds. You\u2019ll see the expected file size before saving, which helps when you need to compress iPhone video for email or squeeze under a platform limit. For example, Discord free users hit a wall at 10 MB (and many complain about it online<\/a>), and most email providers also max out at 25 MB for attachments.<\/li>\r\n\t
- Want more control over quality and file size?<\/b> The Shortcuts app<\/a> (developed by Apple and very likely already installed on your device) lets you re-encode videos with custom settings. It takes a bit more effort but gives you flexibility without losing quality unnecessarily.<\/li>\r\n\t
- Need to also edit the video? <\/b>iMovie<\/a> is your best bet. It\u2019s free, already on most iPhones, and lets you trim clips, add transitions, adjust audio, and apply filters. When you\u2019re done editing, you can downsize a video on iPhone by choosing a lower resolution (1080p or 720p) during export.<\/li>\r\n\t
- Tried everything and still stuck?<\/b> Send an iCloud, Google Drive, or Dropbox link<\/a> instead. The recipient can then either download the original video or stream the video directly in their browser without downloading anything (this depends on the cloud service, with iCloud generally being a bigger pain to work with<\/a> than the rest).<\/li>\r\n<\/ul>\r\n
As you can see, none of the methods above require technical skills or special knowledge. You don\u2019t need to understand codecs or bitrates to make iPhone video smaller. Just pick the approach that fits your situation and follow a few steps to get more storage on iPhone<\/a>.<\/p>\r\n
<\/span>How to Reduce Video File Size on iPhone<\/span><\/h2>\r\n
🤔 How we tested<\/b>: To give you real numbers instead of vague promises, I ran the same test video through every method in this guide. The clip is a 26-second recording shot on an iPhone 17 Pro in 4K (2160*3840) at 60fps using the HEVC (H.265) codec with HDR disabled. Original file size: 178.5 MB. You\u2019ll find the compressed results next to each method so you can compare and pick what works best for your situation.<\/div>\r\n<\/span>Method 1:<\/span> Compress iPhone Videos Using a Third-Party App<\/span><\/span><\/h3>\r\n
📝 Our test results: <\/b>178.5 MB > 106.2 MB (Optimal) \/ 80.6 MB (Medium) \/ 50 MB (Max) | Space saved<\/b>: 40\u201372% | Quality loss:<\/b> None visible at Optimal, minor at Max | Best suited for:<\/b> Freeing up storage quickly<\/div>\r\nIf you want to compress videos on iPhone without messing around with export settings or learning video editing software, Clever Cleaner<\/a> is the fastest option. The app can be used for free, and the whole process takes about 30 seconds. This method is ideal if your main goal is freeing up storage. It\u2019s really fast and convenient, and the app overall unlocks a lot of useful capabilities in this area.<\/p>\r\n
Here\u2019s how to use Clever Cleaner to compress your videos:<\/b><\/p>\r\n
- \r\n\t
- Download Clever Cleaner<\/a> from the App Store and open it.<\/li>\r\n\t
- Grant the app access to your photo library when prompted.<\/li>\r\n\t
- Let it scan your device. This usually takes a few seconds, though larger media libraries may need a couple of minutes.<\/li>\r\n\t
- Tap the Compress<\/b> tool at the top of the screen.<\/li>\r\n\t
- The tool will open in a green window where you\u2019ll see all the videos in your library. Scroll through them, find the video you want to compress, and tap it to open a more detailed view.
![\"Opening](\"\/howto\/wp-content\/uploads\/2026\/08\/open-compress-module-for-videos-clever-cleaner.jpg\")
<\/li>\r\n\t- The app will show you the current file size and the expected size after compression, and you can choose between three compression levels (Optimal, Medium, and Max) depending on how much space you need to save.
![\"Selecting](\"\/howto\/wp-content\/uploads\/2026\/08\/select-level-of-comressing-for-video-clever-cleaner.jpg\")
<\/li>\r\n\t- Tap Compress<\/b> and wait for the process to finish.<\/li>\r\n\t
- Done. Your compressed video is now saved, and you can delete the original directly from within the app using the button that appears after compression.
![\"Starting](\"\/howto\/wp-content\/uploads\/2026\/08\/start-compressing-video-clever-clenaer.jpg\")
<\/li>\r\n<\/ol>\r\nYou can also get to the same compression tool through the Videos<\/b> feature. It sorts your videos by size<\/a>, which can be useful if you\u2019re specifically looking for the biggest storage consumers. Open Videos, switch to the Compress sub-tab, and then follow the same steps above.<\/p>\r\n
📝 Note<\/b>: If your videos are stored in iCloud with the \u201cOptimize iPhone Storage\u201d option enabled, the app will need to download the full-size files first, which may take some extra time depending on your connection.<\/div>\r\nWhat we found after testing all three compression levels: <\/b>My 178.5 MB test video shrank to 106.2 MB with Optimal (41% reduction), 80.6 MB with Medium (55% reduction), and 50 MB with Max (72% reduction). Quality-wise, Optimal produced no visible difference from the original. Medium introduced very slight softness that you\u2019d only notice if comparing side-by-side. Max showed more noticeable compression artifacts, especially in areas with fine detail. For most people, Optimal or Medium hits the sweet spot between space savings and quality retention. Use Max only when you\u2019re desperate for storage and don\u2019t mind some quality trade-off.<\/div>\r\nBeyond video compression, Clever Cleaner also handles duplicate photos<\/a>, similar images, screenshots<\/a>, and Live Photos<\/a>. If your storage is constantly running low, it\u2019s worth exploring those features too. We tested dozens of apps while creating our best iPhone storage cleaner<\/a> ranking, and there\u2019s a reason we put this one in first place.<\/p>\r\n
The app was built by CleverFiles, the same team behind Disk Drill<\/a>, a well-known data recovery tool. As such, it respects user privacy by processing everything locally on your device<\/a>. Your videos never get uploaded to any server, which matters if you\u2019re dealing with personal footage or anything sensitive.<\/p>\r\n
<\/span>Method 2:<\/span> Re-Encode with Shortcuts<\/span><\/span><\/h3>\r\n
📝 Our test results: <\/b>178.5 MB > 76.9 MB (1080p) \/ 54.2 MB (720p) \/ 27.6 MB (540p) | Space saved<\/b>: 57\u201385% | Quality loss:<\/b> Moderate at 540p | Best suited for:<\/b> Users who want a reusable, no-app solution<\/div>\r\nThis method takes the most preparation upfront, but once it\u2019s set up, you can compress iOS video in just a few taps whenever you need to. The goal is to build a custom workflow that re-encodes videos at whatever quality and resolution you choose using the Shortcuts app (pre-installed on every new iPhone).<\/p>\r\n
Here\u2019s how to set it up:<\/b><\/p>\r\n
- \r\n\t
- Open the Shortcuts<\/b> app and tap the +<\/b> button to create a new shortcut.<\/li>\r\n\t
- Tap the dropdown next to \u201cNew Shortcut,\u201d select Rename<\/b>, and call it something like \u201cCompress Video.\u201d<\/li>\r\n\t
- Tap Add Action<\/b> and search for Encode Media<\/b>. This is the action that actually compresses your video. Once added, tap the word Media in the action and change it to Shortcut Input<\/b> (this ensures the shortcut uses whatever video you share with it).<\/li>\r\n\t
- Tap the Show More<\/b> arrow under the Encode Media action to reveal additional settings.<\/li>\r\n\t
- Next to Size<\/b>, tap Passthrough<\/b> and select Ask Each Time<\/b> (this lets you pick the resolution each time you run the shortcut).<\/li>\r\n\t
- Search for and add a second action: Save to Photos<\/b>. Make sure its input is set to \u201cEncoded Media.\u201d<\/li>\r\n\t
- Tap the Info icon<\/b> (\u24d8) at the bottom of the screen, then enable Show in Share Sheet<\/b> and set it to accept Media<\/b> files only.<\/li>\r\n\t
- Tap Done<\/b> to save your shortcut.
![\"Creating](\"\/howto\/wp-content\/uploads\/2026\/08\/create-shortcut-for-video-comressing-and-add-to-share-sheet.jpg\")
<\/li>\r\n<\/ol>\r\nNow, whenever you want to reduce video file size on iPhone, run your shortcut and pick a resolution. The compressed version saves automatically to your photo library.<\/p>\r\n
![\"Compressing](\"\/howto\/wp-content\/uploads\/2026\/08\/compress-video-via-shortcut.jpg\")
<\/p>\r\nWhat we found:<\/b> The shortcut only saves space if you pick a lower resolution than the original. My test video was already recorded in HEVC (H.265), but choosing 1080p reduced the file size to 76.9 MB (57% smaller). Dropping down to 720p brought it to 54.2 MB (70% smaller), while 540p reduced it to 27.6 MB (85% smaller).<\/div>\r\n<\/span>Method 3:<\/span> Downscale and Export in iMovie<\/span><\/span><\/h3>\r\n
📝 Our test results:<\/b>178.5 MB > 36 MB (720p) \/ 17.9 MB (540p) | Space saved<\/b>: 80\u201390% | Quality loss:<\/b> Noticeable at 540p | Best suited for:<\/b> Users who need to trim footage before compressing<\/div>\r\niMovie gives you the most control when you need to both edit and compress a video on iPhone after recording. It\u2019s free, already installed on most iPhones (or you can download it from the App Store), and lets you trim unnecessary footage before exporting at a lower resolution.<\/p>\r\n
The editing part matters because a shorter video means a smaller file. If your 3-minute recording only has 45 seconds of usable content, cutting the rest before compression makes a real difference when clearing iPhone storage<\/a>.<\/p>\r\n
Here\u2019s how to make a video file smaller on iPhone using iMovie:<\/b><\/p>\r\n
- \r\n\t
- Open iMovie<\/b> and tap Start New Project<\/b>, then select Movie<\/b>.<\/li>\r\n\t
- Choose the video you want to compress from your library and tap Create Movie<\/b>.<\/li>\r\n\t
- Your clip appears in the timeline. To trim it, tap the clip, then drag the yellow handles at either end to remove unwanted sections from the beginning or end.<\/li>\r\n\t
- If you need to cut a section from the middle, position the playhead where you want to split, tap the clip, then tap Split<\/b>. Delete the unwanted segment.<\/li>\r\n\t
- When you\u2019re done editing, tap Done<\/b> in the top-left corner.
![\"Starting](\"\/howto\/wp-content\/uploads\/2026\/08\/start-new-project-in-imovie.jpg\")
<\/li>\r\n\t- Tap the Share button<\/b> (the square with an upward arrow) and choose Save or Share Video<\/b>.<\/li>\r\n\t
- Tap Options<\/b> under the video title. Here you can choose your export resolution.<\/li>\r\n\t
- Select a lower resolution to downsize a video on iPhone. Options typically include 1080p HD, 720p HD, 540p, and 360p. I generally go with 720p for general use, but I occasionally choose 540p when I need to fit the video into some strict file size limit.
![\"Selecting](\"\/howto\/wp-content\/uploads\/2026\/08\/select-resolution-to-compress-video-imovie.jpg\")
<\/li>\r\n\t- Tap Done<\/b>, then tap Save Video<\/b> to export the compressed version to your Photos library.<\/li>\r\n<\/ol>\r\n
What we found: <\/b>iMovie did a much better job compressing our 178.5 MB test video, bringing it down to 36 MB at 720p (80% smaller) and 17.9 MB at 540p (90% smaller). The quality loss at 540p is noticeable, especially on larger screens. We also noticed that iMovie changed the way our video looked by adding black bars on the sides. If your main goal is pure compression without editing, Clever Cleaner<\/a> delivers better results without changing the appearance of the video. The Shortcuts method<\/a> from the previous section is another better option if you prefer to stick with built-in tools. But if you need to trim or edit your footage first, iMovie remains a useful option.<\/div>\r\n<\/span>Alternative: Share Links Instead of Trying to Make iPhone Video Smaller<\/span><\/h2>\r\n
Sometimes compression just isn\u2019t the answer. For example, if you\u2019re sending footage to a client or collaborator who needs the original quality, or if the video is so long that even aggressive compression won\u2019t get it under email limits without turning it into a pixelated mess.<\/p>\r\n
In these situations, skip the compression entirely, upload the video to the cloud, and share a link instead.<\/p>\r\n
![\"Copying](\"\/howto\/wp-content\/uploads\/2026\/08\/copy-link-to-share-video.jpg\")
<\/p>\r\nApple\u2019s iCloud<\/a> is the most obvious choice if you\u2019re already in the Apple ecosystem. Videos in your Photos library can be shared via iCloud links, and recipients don\u2019t need an Apple device to view them. There are also Google Drive<\/a>, Microsoft OneDrive<\/a>, and Dropbox<\/a>, all of which arguably handle cross-platform sharing much better.<\/p>\r\n
⚠️ Warning<\/b>: Most cloud services sync deletions across devices. If you delete a video from your iPhone, many services will delete the cloud copy too, potentially breaking any shared links. To avoid this, upload manually to a cloud drive folder rather than relying on auto-sync from your photo library. Always confirm the file exists independently in the cloud before deleting your local copy to free up space.<\/div>\r\n<\/span>Bottom Line<\/span><\/h2>\r\n
The best way to lower video file size on iPhone depends on what you\u2019re actually trying to accomplish. A dedicated app to compress videos like Clever Cleaner<\/a> is the best quick-and-easy solution, but the Shortcuts method<\/a> is also worth exploring if you have a few minutes to set it up. And when you need to trim footage before compressing, iMovie<\/a> gives you editing tools alongside export options.<\/p>\r\n
Based on our testing, Clever Cleaner delivered the best balance of compression and quality retention. Our 178.5 MB test video shrank to 50 MB (72% savings) at the Max setting with acceptable quality loss, while the Optimal setting preserved visual quality almost perfectly at 106.2 MB. The built-in methods reduced the file size even further, but only by dropping the resolution significantly. Shortcuts brought the video down to 27.6 MB at 540p, while iMovie reached 17.9 MB at the same resolution but also added black bars on the sides.<\/p>\r\n
Worth mentioning: the easiest compression happens before you even record. Check your iPhone camera settings and consider whether you really need 4K at 60fps for everyday clips. Shooting at 1080p from the start means smaller files and less hassle later. You can also switch from \u201cMost Compatible\u201d (H.264) to \u201cHigh Efficiency\u201d (HEVC) in Settings<\/b> > Camera<\/b> > Formats<\/b> to automatically reduce file sizes without losing quality.<\/p>\r\n
It\u2019s also a good idea to spend a few minutes getting to \u201cknow your enemy\u201d by memorizing the limits of platforms you use regularly. If you need to lower video file size to send in email, remember that most providers cap attachments at 25 MB. Discord free users hit a wall at just 10 MB. On the other hand, WhatsApp and many other instant messengers compress everything automatically regardless of what you do, so you don\u2019t really need to worry about anything.<\/p>\r\n
