Best Audio Converters in 2026: the buyer's shortlist

ToAny is a file converter that runs in your browser. For audio, that means your file is decoded and re-encoded on your own device. Its contents, name and size are not sent to ToAny. You can check that in your browser's Network panel.

It states 190 formats and 1,195 format pairs across nine categories. Audio pages include WAV to MP3, M4A to MP3, FLAC to MP3, MP3 to WAV and OGG to MP3. It detects the file type from the first bytes, so a mislabelled extension does not matter. You can drop several files and download the results as a ZIP.

It is free, with no account and no email address. The terms say it may show advertising, and none was visible when we checked on 17 October 2026. There is no daily limit on browser conversions. Sixteen document and e-book pairs run on ToAny's own server instead, only after you consent for each file, and no audio pair is among them. The privacy policy lists those pairs.

The weak spots are real. ToAny has no API, no command line, no desktop or mobile app and no offline mode, and it cannot import from cloud storage. Its 190 formats are fewer than CloudConvert's 212. Large files depend on your device's memory, and conversion that falls back to the WebAssembly engine runs at roughly real time, which is slower on a phone.

Choose it when the job is a handful of files and you would rather not install anything.

CloudConvert is a hosted converter that has been running since 2012. It is operated by Lunaweb GmbH in Germany and states 212 formats across 11 categories, 21 of them audio. It also sells a REST API, and its About page says 90% of files are processed through the API.

Your file is uploaded. The privacy policy says selected files are transferred to and temporarily stored on CloudConvert's servers, and deleted automatically after 24 hours at the latest. The security page says files are kept only for processing and deleted straight afterwards, and that the company holds ISO 27001 certification. It says it does not read or mine your files.

The free plan costs EUR 0 and gives 10 conversion credits a day, resetting daily. Maximum file size on the free plan is 1 GB, maximum processing time is 5 minutes and priority is low. Paid plans lift the file size limit. Packages are a one-off payment, subscriptions give monthly credits and unused credits do not roll over. We could not read the paid amounts from the pricing page, so we do not quote them. Credits are consumed at about one per minute of conversion time.

The privacy policy says registration is optional, though the free plan quota comes through sign-up. The About page claims more than 10,000 active customers and 20 files processed per second on average. Trustpilot shows 4.0 from 74 reviews on the Belgian Dutch-language page, and counts move over time.

It beats ToAny on formats and on automation, since ToAny has no API. It loses on privacy, because every file is uploaded, and on the daily cap.

Audacity is a free, open-source audio editor and recorder for Windows, macOS and Linux. Its home page claims 100M+ downloads since 2000 and says it is free for everyone, always. The current version listed on the download page is 4.0.1. Note that the figure counts downloads, not users.

Converting is a side effect of editing. You open a file, change it if you want to, and export it in another format. That makes it a good choice when a conversion comes with other work: trimming a recording, joining takes or adjusting levels before you export.

It is installed software, and its privacy notice says no account is needed. We found no usage cap on the vendor's pages.

Two caveats. The download page lists the FFmpeg import and export library as a separate additional resource, so some formats may need that extra download. We could not confirm from the vendor's pages which formats Audacity exports natively, and it states no format count. And there is no phone version: the manual's FAQ says considerable rewriting would be needed before Audacity works on smartphones, though that FAQ may be dated, and the download page lists none.

Third-party sources, not the vendor, give the project's history. Wikipedia names Dominic Mazzoni and Roger Dannenberg as the creators, and lists the first public release as 28 May 2000. The site footer names Muse Group as the copyright holder.

Next to ToAny, Audacity is the stronger choice when editing is part of the job. For a quick conversion it is slower to start, because you install a full editor first.

VLC is a media player from VideoLAN, a non-profit organisation based in France. It started in 1996 as a student project at École Centrale Paris, became open source in 2001 and has been an autonomous non-profit since 2009. The vendor calls it completely free and says it has no ads.

Its first job is playing files. It makes this list because it also has Convert/Save and streaming features, so if you already have it you may not need a second program. The vendor's pages describe it as playing most codecs with no codec packs needed.

It is the widest platform list here. The vendor lists Windows, Linux, Mac OS X, Unix, iOS and Android. The Windows 64-bit desktop download is 44 MB, and the latest desktop version listed is 3.0.24. The iOS app lists 48 interface languages, and its App Store rating is 3.71682 from 5,982 ratings, checked on 17 October 2026 through Apple's lookup API.

What we could not find is as important. The vendor's pages state no list of output formats, no format count and no documented command or API for conversion. We therefore cannot say how many audio formats it writes. Conversion is a secondary feature of a player, and the pages we read do not market VLC as a converter.

It is installed software, and none of the pages we read mention a usage limit.

Compared with ToAny, VLC reaches more platforms, phones included. A single conversion is easier in ToAny, since VLC needs installing and conversion is not its main job.

FFmpeg is a command-line tool and a set of libraries for converting multimedia files. The project describes itself as a complete, cross-platform solution to record, convert and stream audio and video, and its home page shows a one-line conversion: ffmpeg -i input.mp4 output.avi.

It is free and open source under the LGPL version 2.1 or later. The site lists funding through SPI and a Donate link. It states no format count, only that it handles pretty much anything. That is a claim, not a number, and we cannot compare it with CloudConvert's 212.

Its strength is automation. The libraries, including libavcodec, libavformat and libavfilter, are usable by other applications, and the command line runs in scripts, so you can convert a folder of files in one loop. ToAny's own fallback engine is an FFmpeg build compiled to WebAssembly.

The cost is a learning curve. There is no window and no drop zone: you type commands and read their errors. The project ships source code only, and compiled builds for Linux, Windows and macOS come from third-party links on its download page. The current release listed there is FFmpeg 9.0.2 "Lei".

The project's pages state no usage cap. Set against ToAny, FFmpeg gives far more control over scripting and batches, and it is the wrong tool for anyone who does not want a terminal.

Movavi is a Cyprus-based software company, founded in 2004, that sells a desktop Video Converter and runs a free online converter. The desktop app states 180+ formats and runs on Windows 10 and 11 (64-bit) and macOS 12.0 or higher. The company says it has millions of users but gives no figure.

Prices were shown in Australian dollars to an Australian visitor. The desktop product page shows 95.95 AUD including VAT. The buy page shows a 1-month subscription at 27.95 AUD and a 1-year licence at 63.95 AUD, discounted from 91.95 AUD, with the offer valid until 18 October 2026. A Lifetime option exists, but we did not read its price. A 14-day money-back guarantee covers technical problems that cannot be solved.

The trial matters for audio. The vendor lists a 7-day trial, a watermark on output videos and, when converting audio files, an ability to convert only half the file length. If audio is your job, you cannot fully test it before paying.

The online converter works differently: you upload the file to Movavi. Our sources do not state how long uploads are kept, and they do not say whether the desktop app processes locally.

Reviews come from the vendor's own pages. They show 5.0 from 57 reviews, linking to Capterra, and 4.8 on G2 with no count shown. We did not read either review site, so treat both as vendor claims.

Movavi offers a desktop app and a money-back guarantee, which ToAny does not. ToAny is cheaper, and it has no half-length trial limit to work around.
