What is AMR?
Adaptive Multi-Rate — a speech codec built for mobile phones. It's what many Android and older phones save voice recordings and voice memos as, and what MMS voice messages use. Highly compressed and optimized for the human voice, so files are tiny but not suited to music.
What is MP3?
The most widely used audio format. Great compatibility, small file size. Ideal for music, podcasts, and general use.
Why Convert AMR to MP3?
AMR (Adaptive Multi-Rate) is the speech codec many phones use to record voice memos and voice messages. It's brilliant at what it was designed for — squeezing spoken audio into a tiny file — but that specialization is exactly why AMR files are a headache to play. Windows Media Player, most music apps, a lot of web players, and plenty of car stereos simply don't recognize .amr files, so a recording that plays fine on the phone that made it becomes unplayable everywhere else. Emailing an AMR voice note to someone often means they can't open it at all. Converting to MP3 fixes that in one step: MP3 is the single most widely supported audio format on earth, so the recording will play on any device, in any browser, in any editor, and attach cleanly to any email or message. Because AMR is already a lossy speech format, converting to MP3 doesn't recover detail that was never there — but it doesn't need to. Voice recordings are about intelligibility, and MP3 preserves that perfectly while making the file universally playable. This converter decodes the AMR with FFmpeg compiled to WebAssembly and re-encodes it to MP3 right inside your browser, so your voice recordings — which are often private — never get uploaded to a server. It's the quickest way to make an old voice memo, an MMS voice message, or a batch of phone recordings usable outside the phone that captured them.
Who Uses This Converter
Play phone voice memos anywhere
Voice memos recorded as AMR won't open in most desktop players. Convert to MP3 and they play on any computer, phone, or web app.
Open MMS voice messages
Voice messages sent over MMS arrive as .amr and often can't be opened outside the messaging app. MP3 makes them universally playable.
Email and share recordings
An AMR attachment frequently can't be opened by the recipient. Sending an MP3 instead means it plays for everyone, on any device.
Archive old phone recordings
Convert a batch of legacy AMR recordings to MP3 so your archive stays playable years from now, regardless of the app that made them.
Frequently Asked Questions
How do I convert an AMR file to MP3?
Drop your .amr file into the converter above and it becomes an MP3 you can download. Everything runs in your browser — no upload, no signup, and nothing is sent to a server. Most voice recordings convert in a second or two.
What is an AMR file and why won't it play?
AMR (Adaptive Multi-Rate) is a speech codec built for mobile phones, commonly used for voice memos and MMS voice messages. It plays on the phone that recorded it but many desktop players, music apps, and browsers don't support it — which is why converting to widely-supported MP3 makes it playable everywhere.
Will converting AMR to MP3 improve the audio quality?
No — AMR is already a compressed speech format, and converting to MP3 can't restore detail that was never recorded. What it does is make the file universally playable. For voice recordings, which are about clarity of speech, MP3 preserves the intelligibility perfectly.
Is it safe to convert private voice recordings here?
Yes. The conversion happens entirely inside your browser using FFmpeg WebAssembly — your AMR file is never uploaded to any server. After the page loads you can even go offline and it still works, which proves nothing is being sent anywhere.
Can I convert AMR voice messages from my phone?
Yes — that's the most common use. Transfer the .amr file from your phone to your device (or open this page on the phone's browser) and drop it in. The MP3 you get back will play in any app and can be emailed or shared without compatibility problems.
Is this AMR to MP3 converter free?
Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
