Convert to MP3 on iPhone: Videos, Voice Memos and Audio Files

This guide walks through every common case on an iPhone: videos from the Camera app, Voice Memos recordings, screen recordings, voice notes and audio files saved in Files. You'll also find which bitrate to pick, where the MP3 ends up, what limits to expect and how to fix the problems people run into most often.

Can you convert files to MP3 on an iPhone without an app?

Yes. iOS doesn't have a menu that exports a video or a recording as MP3. Apple's own apps save audio in other formats: Voice Memos exports M4A files, and the Camera app records video, usually as MOV. A converter that runs in the browser fills the gap.

Convertola's MP3 converter runs inside Safari. The page downloads its conversion engine, which is FFmpeg compiled to WebAssembly, and then your file is processed on the iPhone itself. It isn't uploaded to a server. That matters for private recordings such as meetings, family videos or voice notes.

What you need:

• A recent version of iOS and Safari, or another current browser that supports WebAssembly.
• The file saved on the iPhone, in Photos or in the Files app.
• Enough free memory for the file. Very long videos are easier to convert on a computer.
• A stable connection the first time you open the page, so the conversion engine can load.

Why not just install a converter app?

You can, but think about what an app asks for. Many free converter apps show heavy ads, push subscriptions or ask for access to your whole photo library. For a file now and then, the browser is simpler: nothing to install, nothing left on the phone afterwards, and no new permissions. An app can make sense if you convert files every day and want them organized in one place.

Which iPhone files can you convert to MP3?

These are the files people most often want as MP3, and the page to use for each one:

Convertola accepts MP4, MOV, WEBM, MKV, MPEG/MPG, M4A, AAC, WAV, FLAC, OGG, OPUS and MP3 files up to 150 MB, one file at a time. If you're not sure of the format, use the general MP3 converter, which accepts all of them.

How do you check a file's format on iPhone?

In the Files app, touch and hold the file and choose Get Info. The kind and the full name with its extension appear at the top. In Photos, swipe up on a video to see details. Photos doesn't always show the extension, so if you need to know it, save the video to Files first (Share, then Save to Files) and check it there.

How do you convert a video to MP3 on iPhone?

1. Open Video to MP3 in Safari.
2. Tap the file area. iOS offers the Photo Library, the camera or Browse/Choose File. Pick your video.
3. Choose the bitrate: 192 kbps (the default) for music or mixed audio, 128 kbps for speech.
4. Tap Convert to MP3 and keep the page open until the progress bar finishes.
5. Tap Download MP3. Safari saves the file to its download location, usually Files > Downloads.

If the Photo Library option gives an error, save the video to Files first (open it in Photos, tap Share, then Save to Files) and pick it with Browse. Convertola keeps the first audio track of the video.

Should you choose the Photo Library or Browse?

Both work for most videos. When you pick from the Photo Library, iOS may prepare a copy of the video before handing it to Safari, and for some formats it can convert it to a more compatible version first. That's normal, but it can take a moment on long clips. Picking the file from Files with Browse hands Safari the file exactly as it is saved. If a video from Photos fails, the Files route usually fixes it.

What if the video is stored in iCloud?

With Optimize iPhone Storage turned on, older videos may live in iCloud with only a small preview on the phone. iOS has to download the full video before Safari can read it, so the first step can take longer and needs a connection. If the picker seems stuck, open the video in Photos first and let it finish loading, then try again.

How do you convert a Voice Memo to MP3?

Voice Memos keeps recordings inside the app, so export the file first. Apple's instructions say a recording is exported as an .m4a file by default.

1. Open Voice Memos, tap the recording, tap the More button (three dots) and choose Share.
2. Scroll down, tap Save to Files and choose a folder.
3. Open M4A to MP3 in Safari and pick the file with Browse.
4. Choose 128 kbps. That's enough for speech and keeps the file small.
5. Convert, then download the MP3.

If you recorded music or a performance with Voice Memos, 192 kbps is a safer choice. The original recording is already compressed as AAC inside the M4A file, so going higher than 192 kbps rarely adds anything you can hear.

Why convert a Voice Memo at all?

M4A plays on iPhones, Macs and most modern computers, so you only need MP3 when something else asks for it: an older MP3 player, a car stereo that only reads MP3 from a USB stick, a website upload form, a transcription service or a colleague on an older system. MP3 is the format almost every device and program accepts.

How do you convert a screen recording to MP3?

A screen recording is a video, so the steps are the same as for any video. The extra check is sound. iPhone screen recordings only include audio from the microphone if you turn it on before you start: in Control Center, touch and hold Screen Recording and tap Microphone. Apple also notes that some apps don't allow their audio to be recorded.

1. Play the recording in Photos and make sure you can hear it.
2. Open Video to MP3 in Safari and choose the recording.
3. Pick 128 kbps for speech or 192 kbps if it includes music.
4. Convert and download.

Screen recordings often show private messages or notifications, which is another reason to use a converter that doesn't upload the file. The screen recording to MP3 guide covers Mac and Windows as well.

How do you convert an audio file from the Files app?

Audio files often arrive by email, AirDrop or a cloud drive and end up in Files. WAV and FLAC files from a recorder or a music download, AAC files from another phone and OPUS voice notes are the usual ones.

1. Make sure the file is saved on the iPhone or in iCloud Drive, not only attached to an email. In Mail, touch and hold the attachment and choose Save to Files.
2. Open Audio to MP3, or the specific page for the format, in Safari.
3. Tap the file area, choose Browse and find the file.
4. Choose a bitrate. For WAV or FLAC music, 256 or 320 kbps keeps the most detail.
5. Convert and download.

For a WAV file, remember that uncompressed audio is large. At CD quality it takes about 10.6 MB per minute, so the 150 MB limit works out to roughly 14 minutes of WAV.

Which bitrate should you use on iPhone?

These sizes follow directly from the bitrate: kilobits per second times 60 seconds, divided by 8 to get bytes. A higher bitrate won't improve a source that is already compressed, such as an M4A voice memo or the AAC track in an iPhone video. It only makes the file bigger. The MP3 bitrate guide explains why.

What to choose

• Mostly talking (lectures, meetings, interviews, voice memos): 128 kbps.
• Music or a mix of music and voice from videos: 192 kbps.
• Music from a lossless file (WAV, FLAC) that you want to keep: 320 kbps.
• Not sure: leave it at 192 kbps.

Where is the MP3 saved on your iPhone?

Safari stores downloads in a folder you can choose. By default it's Downloads in iCloud Drive or On My iPhone. To find the MP3:

1. Open the Files app and tap Browse.
2. Open iCloud Drive > Downloads or On My iPhone > Downloads.
3. Tap the MP3 to play it, or touch and hold it to share, move or rename it.

You can also tap the downloads button in Safari's address bar right after the download finishes. To change where Safari saves files, open Settings, go to Safari (in recent iOS versions it's under Settings > Apps > Safari) and tap Downloads.

Can you add the MP3 to the Music app?

The Music app on iPhone doesn't import files directly from Files. The usual way to get your own MP3s into the Music library is to add them on a Mac or PC and sync them to the iPhone. For simply listening, you can play the MP3 straight from Files, or open it in another audio app that reads files.

What limits should you expect on an iPhone?

• 150 MB per file. iPhone video uses tens of megabytes per minute, so a few minutes of 4K or 1080p footage can reach the limit. For long videos, use a computer. See convert to MP3 on a Mac.
• One file at a time. Convert, download, then pick the next one.
• Keep Safari in front. If you switch apps or lock the screen during a long conversion, iOS may pause the tab.
• Memory. Older iPhones with little free memory can stop on very large files. Close other tabs and try again.
• Protected files. Apple Music downloads and old protected iTunes purchases can't be converted.

What if the conversion doesn't work?

Most problems on an iPhone have a simple cause. Work through these in order:

How do you trim a video before converting?

Trimming makes the file smaller and the conversion faster. In Photos, open the video, tap Edit, drag the yellow handles on the timeline to the part you want, then tap Done and choose to save the video as a new clip so you keep the original. Convert the shorter clip.

Is it safe to convert files on an iPhone in the browser?

With a converter that processes files on the device, your file never leaves the phone. That's the key thing to check on any converter site. Also watch for warning signs: pages that ask you to install a profile or an app, pop-ups claiming your phone has a virus, and download buttons that lead somewhere other than an .mp3 file. A legitimate converter works on files you already have and gives you one clear download. The guide on choosing the best MP3 converter lists more checks.

Frequently asked questions

Can I convert a video to MP3 on iPhone without an app?

Yes. Open a browser-based converter such as Convertola in Safari, choose the video from Photos or Files, pick a bitrate and download the MP3. Nothing needs to be installed.

Where does the MP3 go after downloading on iPhone?

Safari saves downloads to its download location, usually the Downloads folder in the Files app. Open Files, tap Browse and look in Downloads.

Is my video uploaded when I convert it?

Not on Convertola. The MP3 converter runs in Safari. The page downloads the conversion engine, and your file is processed on the iPhone and isn't sent to a server.

Can I convert Apple Music songs to MP3 on iPhone?

No. Songs from the Apple Music subscription are protected, and Convertola only converts unprotected files you already have, such as your videos, voice memos and audio files.

What bitrate should I use for a voice memo?

128 kbps. Speech doesn't benefit from a higher bitrate, and the voice memo is already compressed, so a higher setting only makes the file bigger.

Why is my converted MP3 silent?

The original file most likely has no sound. Screen recordings only include the microphone if you turned it on before recording. Play the original first, and if it's silent, record it again with audio on.

Can I convert a long video on my iPhone?

Up to 150 MB per file. Long 1080p or 4K videos pass that quickly. Trim the video in Photos first, or convert it on a computer.
