A Comprehensive Guide on Compressing Videos on iPhone

Built-in Video Compression Options on iPhone

If you’re running low on storage space or need to send a video through email or messaging, compressing the video on your iPhone is a great option. The good news is that Apple has built-in compression options on the iPhone, making it easy to compress videos without needing to install any third-party apps. Here are the steps to follow:

  1. Open the Photos app on your iPhone.
  2. Find the video you want to compress and tap on it.
  3. Tap on the Share icon at the bottom left corner of the screen.
  4. Scroll down and select “Save Video”.
  5. Choose the desired compression option – Small, Medium, or Large File size.
  6. Wait for the compression process to complete, and the compressed video will be saved to your camera roll.

Keep in mind that compressing the video will reduce its quality and resolution. So, if you’re looking to preserve the original quality, it’s best to go for third-party apps or follow some tips to reduce video size without compromising quality.

Third-Party Apps for Video Compression

While Apple’s built-in compression options are convenient, they may not always offer the level of control and customization you need. In that case, you can turn to third-party apps that are specifically designed for compressing videos on iPhone. Here are some popular options:

  1. Video Compressor – This app allows you to select the compression level, resolution, and output format of the video. You can also preview the compressed video before saving it.

  2. Video Slimmer – With Video Slimmer, you can compress videos by adjusting the bitrate, frame rate, and resolution. The app also supports batch compression, allowing you to compress multiple videos at once.

  3. iMovie – Although iMovie is primarily a video editing app, it also offers video compression features. You can trim and crop the video, adjust the resolution, and export the video at a lower quality.

  4. Handbrake – Handbrake is a powerful video compression tool that’s available for free on desktops. It’s a bit more complicated to use than the other options on this list, but it offers more advanced features and customization options.

Each of these apps has its pros and cons, so it’s worth trying out a few to see which one works best for your needs.

Tips for Reducing Video Size Without Compromising Quality

If you want to reduce the size of your videos without sacrificing quality, here are some tips to keep in mind:

  1. Shorten the length of the video – The longer the video, the larger the file size. So, consider shortening the video by trimming unnecessary footage.

  2. Lower the resolution – Higher resolutions (like 4K) produce larger file sizes. If you don’t need the video to be in high definition, consider lowering the resolution to 1080p or 720p.

  3. Adjust the frame rate – A higher frame rate (like 60fps) will produce a larger file size. If the video doesn’t require a high frame rate, consider lowering it to 30fps or lower.

  4. Reduce the bitrate – A lower bitrate will result in a smaller file size, but it can also affect the quality of the video. Experiment with different bitrates to find the sweet spot between file size and quality.

  5. Use a codec that produces smaller file sizes – Codecs like H.265 (HEVC) and VP9 are more efficient than older codecs like H.264, producing smaller file sizes without sacrificing quality.

By using these tips in combination with built-in compression options or third-party apps, you can significantly reduce the size of your videos without compromising their quality.

Uploading Compressed Videos to Different Platforms

Once you’ve compressed your video, you may want to upload it to different platforms like social media, messaging apps, or video hosting sites. Here are some tips for uploading compressed videos to various platforms:

  1. Social media platforms like Facebook, Instagram, and Twitter often have built-in compression algorithms that further compress the video. So, it’s best to compress the video to a higher quality than you need to compensate for the further compression.

  2. Messaging apps like WhatsApp and iMessage have file size limits, so make sure the compressed video is within the size limit. You can also try using the built-in compression options in the app to further reduce the file size.

  3. Video hosting sites like YouTube and Vimeo have recommended compression settings, so make sure to follow those guidelines to ensure the best quality. You can also experiment with different compression settings to find the optimal balance between file size and quality.

  4. If you’re sending the video via email, make sure the compressed video is within the file size limit. You can also use cloud services like Dropbox or Google Drive to share the video without worrying about file size limits.

By following these tips, you can ensure that your compressed videos look and sound their best on different platforms.


Compressing videos on iPhone can be a lifesaver when you’re running low on storage space or need to share a video quickly. Whether you use Apple’s built-in compression options or third-party apps, it’s essential to keep in mind the balance between file size and quality.

By following the tips outlined in this guide, you can reduce the size of your videos without compromising their quality. And when it comes to uploading compressed videos to different platforms, make sure to follow the guidelines and recommended settings to ensure the best quality.

With the right tools and knowledge, you can easily compress videos on your iPhone and enjoy more space and faster sharing options.
