How to Convert Video to Audio on iPhone: What You Need to Know

Converting a video file to an audio-only format on an iPhone is a genuinely useful task — whether you want to extract a song from a recorded performance, save a podcast interview as an MP3, or strip the audio from a video to reduce file size. The good news is that it's entirely doable on iOS. The less obvious part is that how you do it depends on your iOS version, your tolerance for third-party apps, and what you plan to do with the audio afterward.

Why iPhones Don't Do This Natively (And When They Partially Do)

Apple's built-in tools are surprisingly capable, but video-to-audio conversion isn't a standard feature in the Photos app or Files app. You can trim, edit, and share videos natively, but extracting audio as a standalone file — say, an MP3 or M4A — requires either the Shortcuts app or a third-party solution.

That said, iOS does work with audio formats natively. Files saved as .m4a (MPEG-4 Audio) are fully supported across Apple's ecosystem, and many conversion tools on iPhone will default to this format. If you need MP3 specifically — for compatibility with non-Apple devices or platforms — that adds a layer of consideration.

Method 1: Using the Shortcuts App (Built-In, No Downloads Required)

The Shortcuts app, available on iOS 13 and later, is the most underrated tool for this kind of task. It can automate the process of pulling audio from a video file and saving it to your Files app or Music library.

Here's the general approach:

1. Open the Shortcuts app (pre-installed on modern iPhones)
2. Create a new shortcut or find a pre-built one via the Shortcuts Gallery
3. Use the "Encode Media" action, which accepts a video input and lets you toggle "Audio Only" to on
4. Add a "Save File" action to store the output in iCloud Drive or On My iPhone
5. Run the shortcut on any video from your Photos library or Files app

The output format using this method is typically .m4a, which plays natively in the Music app and most audio players. 🎵

Key variable here: The Shortcuts app behavior and available actions can differ between iOS versions. On iOS 15 and later, the Encode Media action is more stable and reliable than on earlier builds.

Method 2: Third-Party Apps

If you want more control over output format, bitrate, or batch processing, third-party apps are worth considering. The App Store has a range of options — some free with limitations, others paid or subscription-based.

Common categories of apps used for this:

When evaluating any third-party app, the factors that matter most are:

• Output format support — does it produce MP3, M4A, or both?
• Bitrate control — important if audio quality is a priority
• File size limits — some free tiers cap how large an input file can be
• iCloud and Files integration — affects where you can import from and export to

Method 3: Using a Mac (If You Have One in the Ecosystem)

If you're working within the Apple ecosystem and have access to a Mac, iMovie and GarageBand both allow you to import video and export audio. This is often faster and more reliable for longer or higher-quality files.

With AirDrop or iCloud Drive, transferring the file from iPhone to Mac and back takes under a minute in most cases. QuickTime Player on Mac also supports audio-only export directly from a video file — no third-party software required.

This route makes more sense if you're regularly doing this kind of conversion, working with large files, or need professional-grade output quality.

The Format Question: M4A vs. MP3 vs. Others

The format you need matters more than most people realize before they start. 🎧

• M4A (AAC): Apple's native audio format. Excellent quality-to-size ratio, plays natively on all Apple devices. Less universal on Android or older devices.
• MP3: The most universally compatible format. Slightly larger file size than M4A at equivalent quality, but works everywhere.
• WAV: Uncompressed, high quality, large file size. Useful for audio editing but not practical for casual listening.
• FLAC: High-quality lossless format, not natively supported on iOS without a third-party app.

Most casual use cases — saving a voice memo, capturing a live performance, extracting a spoken word recording — are well served by M4A or MP3. The distinction becomes important when you know the file needs to work on a specific platform, device, or within a particular workflow.

Variables That Shape Your Best Approach

Before deciding which method to use, a few things are worth thinking through:

• iOS version — Shortcuts functionality varies, and some apps require newer OS versions
• File source — Is the video in your Photos library, iCloud Drive, or downloaded from elsewhere?
• Intended use — Background listening, sharing, editing, archiving?
• Output format requirements — Does the destination platform require a specific format?
• File length and size — Longer videos may hit limits on certain free apps
• How often you'll do this — A one-time task calls for a different approach than a recurring workflow

Different Users, Different Solutions

Someone extracting a 30-second clip from a personal video to use as a ringtone has a very different set of requirements than someone regularly converting hour-long interview recordings for a podcast archive. A user deeply embedded in the Apple ecosystem — iPhone, Mac, iCloud — has access to seamless native options that someone working cross-platform might not fully leverage.

Even within iOS-only setups, the right combination of Shortcuts actions, preferred audio formats, and storage destinations varies enough that there isn't a single universal answer. What your setup looks like, what the audio needs to do after conversion, and what tools you already have access to are the pieces that ultimately determine which path makes the most sense for you.
