Best MP4 to MP3 Converters in 2026: the buyer's shortlist

ToAny converts MP4 to MP3 in your browser. The video is read from disk on your own device, the soundtrack is encoded there and the MP3 is saved from browser memory. Nothing is uploaded, and you can check that in your browser's Network panel. MP4 to MP3 is not one of the 16 pairs that run on ToAny's server, and those 16 are all documents and e-books, each with a consent step before upload.

It is free, needs no account or email and adds no watermark. You can add several files, convert them together and download one ZIP. Under Options you choose the bitrate, which is 192 kbps unless you change it, and you can trim the start and end. The page accepts files up to 2 GB and uses your browser's own video and audio codecs, with hardware acceleration where the device has it.

ToAny is not the strongest choice for every job. It has no API, no cloud import from Google Drive or Dropbox, no desktop app and no offline mode. Your device does all the work, so very large files are bounded by its memory, and video conversion can be slow on phones. For MOV files, the same approach is on the MOV to MP3 page. Where a browser lacks a codec, the page falls back to a compatibility engine that runs at roughly real time and accepts files up to 1 GB.

It states 190 formats and 1,195 pairs, which is fewer than AnyConv, Convertio, CloudConvert or VideoProc. It is also young. It went live on 5 October 2026, so its track record is short.

AnyConv is a free server-side converter with a dedicated MP4 to MP3 page that accepts several files at once. You upload the video, AnyConv converts it on its servers and you download the MP3. No account is required.

The limits are plain. Files up to 100 MB are accepted, and you can convert up to 60 files per hour. The site says it plans to raise the 100 MB limit. AnyConv states over 300 formats and 22 languages, which is more formats than ToAny's 190.

On privacy, AnyConv uploads the file. It says it processes files on European servers, with data centres in Germany and Finland, deletes input files right after conversion and keeps output files for 1 hour. It uses third-party advertising and names Google AdSense in its privacy policy.

AnyConv says it has operated since 2019 and reports 60,000+ users per day and 50+ million files converted since then. These are self-reported figures. The about page names no founder, only a current lead, and we found no review-platform ratings we could verify.

The MP4 to MP3 page we read does not state any bitrate options, and we found no desktop app. We found no paid plan. The trade-off is the 100 MB ceiling, which a long recording can exceed.

CloudConvert is a server-side converter and API run by Lunaweb GmbH, near Munich in Germany. It has a dedicated MP4 to MP3 tool with options for video resolution, quality and file size, and it states 212 formats across 11 categories, 21 of them audio.

The free plan costs EUR 0 and gives 10 conversion credits per day, with files up to 1 GB. Free jobs have a 5-minute maximum processing time, 5 concurrent tasks and low priority. A credit is about one minute of conversion time. Paid plans are a one-off package whose credits never expire, a monthly subscription or an enterprise deal. The exact paid prices were not readable on the page we saw, so we do not quote them.

CloudConvert uploads your file. It says files are deleted automatically after 24 hours at the latest, that it does not read or mine file data and that its security management is ISO 27001 certified by TUV Sud. These are the vendor's own security claims, and it is still an upload.

CloudConvert says it was founded in 2012 and has 10,000+ active customers, and that 90% of its files go through the API. Its Trustpilot page showed 4.0 from 74 reviews on the nl-be site, and counts move over time.

The main strengths are the API, the output controls and the 1 GB free ceiling. The main weakness is the credit model, which makes heavy video jobs harder to predict than a flat limit.

Convertio is a server-side converter that states 300+ formats, an API and cloud import. Besides local files, the upload box takes files from Dropbox and Google Drive. That makes it the clearest answer to a need ToAny does not meet.

Paid plans are billed in credits, which measure server time. Monthly billing is Lite at $11.99, Basic at $22.99 and Pro at $44.99, with Custom from $54. Billed annually, Lite falls to $6.99 a month. Lite allows files up to 1 GB, 1000 credits a month and 50 concurrent conversions. All plans have unlimited conversion minutes per day and no limit on conversion time per file. The pricing page says there are no refunds once you upgrade, because a free tier exists. It does not clearly state the free tier's limits.

Convertio uploads your file. It says input and temporary files are deleted immediately after conversion and outputs after 24 hours, and that its infrastructure is in Germany. The paid plans list ad-free pages, which implies the free tier shows ads.

Convertio says it started in 2014. Its home page showed a counter of 3,191,036,609 files converted on 17 October 2026, which is a count of files rather than users. Trustpilot showed 4.9 from 10,601 reviews, though Trustpilot notes the company has not invited customers recently or replied to negative reviews. The on-site 4.6 rating is self-hosted, so we do not treat it as independent.

FreeConvert is a server-side converter and compressor with a dedicated MP4 to MP3 tool. It says it supports more than 1500 conversions. A REST API exists, and the free minutes are shared between the website and the API.

Free use needs no account on the website. You get 20 conversion minutes per day, up to 5 conversion minutes per file, and files up to 1 GB. The metering is the catch. A long video can use the allowance quickly, and FreeConvert's own upsell implies the free tier has ads and a queue.

Paid plans start at $12.99 a month for Basic, with 1,500 conversion minutes and files up to 1.5 GB. Standard is $24.99 with 2,000 minutes and 2 GB. Pro is $29.99 with 4,000 minutes and 5 GB. Paid plans list no ads, and the yearly toggle advertises two months free.

FreeConvert uploads files to servers on AWS in Ireland and deleted automatically after 8 hours, with manual deletion possible. FreeConvert says it does not view files without explicit written consent.

FreeConvert says it launched in 2018, offers 15 interface languages and gets 11M+ monthly visitors. Trustpilot showed 17,404 reviews. The vendor claims 4.7 from 17,000+ reviews without naming the platform, so we do not rely on that figure.

It is a sensible free option for a one-off job under 1 GB, as long as the file can be uploaded.

VLC is a free, open-source media player from the non-profit VideoLAN. It is a player first. The pages we read do not describe an MP4 to MP3 workflow, so treat it as a do-it-yourself route rather than a dedicated converter.

Because it is installed software, the file stays on your machine. Nothing is uploaded, and we found no stated size limit or account requirement. VideoLAN says VLC is completely free, with no ads, spyware or user tracking. That is a vendor claim, and it is the only price you will see.

VLC runs on Windows, Linux, Mac OS X, Unix, iOS and Android. The latest desktop version listed was 3.0.24, and the Windows 64-bit download was 44 MB. VideoLAN started as a student project at Ecole Centrale Paris in 1996, became open source in 2001 and has been an autonomous non-profit since 2009. It is based in France.

The cost is effort. You need to install it and find the conversion menu, and the pages we read name no bitrate or batch controls for this job. We did not source a format count or conversion limits. VLC for iOS has an App Store average of 3.71682 from 5982 ratings.

If VLC is already on your computer, it is a fair choice for a one-off conversion. If it is not, a browser tool is quicker to start.

Movavi is a Cyprus-based software company that sells Video Converter as a paid Windows and Mac desktop app. It also runs an Online Video Converter, which uploads your file. The online page does not state how long uploads are kept.

The desktop trial is limited. It lasts 7 days, adds a watermark to output videos and converts only half the length of audio files. For an MP4 to MP3 job, that half-length rule is the one that matters. A trial MP3 will be cut short.

Prices were shown in Australian dollars including VAT to an Australian visitor, and may differ elsewhere. A 1-month subscription was 27.95 AUD. A 1-year subscription was 63.95 AUD, discounted from 91.95 AUD, in an offer valid until 18 October 2026. The desktop product page showed 95.95 AUD with no billing period. A lifetime option exists, but we could not read its price. Movavi offers a 14-day money-back guarantee for technical problems it cannot solve.

The desktop app states 180+ formats and runs on Windows 10 and 11 64-bit and macOS 12.0 or higher. The online converter lists 19 language versions. Movavi was founded in 2004 and is based in Limassol, Cyprus.

The vendor page quotes 5.0 from 57 reviews on Capterra and 4.8 on G2. We did not read those review pages directly, so treat the figures as vendor claims.

VideoProc Converter AI is a paid Windows and macOS desktop app from Digiarty Software for converting, compressing, editing, downloading and recording video. It uses your own GPU for speed, and it converts to MP3, WAV, WMA, M4A and OGG.

It is the broadest product on this list. It states 370 input codecs and 420+ output formats, which is well above ToAny's 190. The free trial needs no sign-up or credit card. Conversion, compression, editing and audio tools are limited to files under 5 minutes, but there is no file-size limit per task.

Prices are time-limited sale prices. Premium 365, a 1-year subscription for 3 PCs or Macs, was $34.95, down from $59.95. It auto-renews at $39.95. A Lifetime License for 1 PC or Mac was $54.95, down from $89.95, and a Family License for 3 to 5 PCs or Macs was $79.95, down from $159.95. There is a 30-day money-back guarantee.

The vendor says it has 5.2 million users from 180+ countries, a figure we could not verify. Its parent, Digiarty Software, was established in 2006.

The privacy position is less clear than its local design suggests. The privacy policy says only that logs are seen if you send them, with no explicit statement that files never leave the device. VideoProc is also heavy for a simple MP3 extraction. Much of the product is aimed at editing and AI tools.
