Quick answer: The best audio converter in 2026 is the CoolUtils Total Audio Converter. Install it, add a file or a whole folder, choose an output format (MP3, WAV, FLAC, OGG, AAC, WMA, APE or OPUS) and click Start. It converts in batch, rips CDs, splits albums by CUE sheet, keeps your ID3 tags, runs from the command line for automation, and works offline for a one-time $24.90 — no subscription, no upload.
An audio file in the wrong format is useless: a FLAC rip that your phone refuses to play, a WAV too big to email, an APE album your car stereo cannot read. The moment you need MP3 for portability, FLAC for archiving, or OGG for a game engine, you need a converter — and not every tool handles a folder of 500 tracks, a CD, a CUE-split album or an offline workflow.
We screened 10 desktop and online audio converters, then put the 6 most capable through the same test: convert a single FLAC to MP3 and back, convert a folder of 50 tracks in one run, rip a CD to FLAC and to MP3, split an APE+CUE album into per-track files, preserve every ID3 and Vorbis tag, and automate a conversion from the command line. Here is how they ranked.

The 6 best audio converters, ranked
1
CoolUtils Total Audio Converter
Windows · 79 MB · $24.90 one-time
Best overall & best for batch + automation
The CoolUtils Total Audio Converter was the only tool in our test that combined wide format coverage, true folder-level batch conversion, CD ripping and command-line automation in one $24.90 desktop app. It turns a track — or a whole folder of them — into MP3, WAV, FLAC, OGG, AAC, WMA, APE, MPC and OPUS, with 30+ formats in all, and it keeps your folder structure on the way out.
Three things put it on top. First, it rips audio CDs straight to a lossless format like FLAC or a compressed one like MP3, reading CDA tracks the others ignored. Second, it splits APE and FLAC albums by their CUE sheet into clean per-track files with the right tags. Third, the command-line build lets you wire conversions into a .bat file or a scheduled task — convert every track dropped into a folder overnight. It preserves and edits ID3, Vorbis and APE metadata plus album art, can capture audio from YouTube or SoundCloud, has no file-size limits and a built-in player, and everything runs offline. The trial is 30 days with no credit card or email.
Pros
- True batch conversion of whole folders, structure preserved
- 40+ formats: MP3, WAV, FLAC, OGG, AAC, WMA, APE, OPUS
- Rips CDs and splits APE/FLAC albums by CUE sheet
- Command-line build, keeps ID3 tags and art, one-time $24.90
Cons
- Windows only (runs under Citrix; no native Mac build)
- Focused on converting and ripping, not deep waveform editing
- No free tier (but a 30-day full trial and a one-time price)

dBpoweramp
Windows / Mac · from $49 once
Best ripping accuracy
dBpoweramp is the audiophile favourite, with excellent encode quality, accurate (AccurateRip) CD ripping and solid metadata. It is the most refined ripper we tested — and the priciest, with no free tier. Batch conversion is good, but scripting is only partial, and the Reference edition costs more than our winner. If you live in a lossless library it is superb; for everyday folder conversion it is more than most people need.
Pros
- Best-in-class encoding and AccurateRip CD ripping
- Excellent metadata and DSP effects
- Cross-platform
Cons
- No free tier, pricier than our winner
- Only partial command-line scripting
- More tool than casual users need
3
fre:ac
Windows / Mac / Linux · free, open-source
Best free open-source pick
fre:ac is a genuinely capable free converter: it handles MP3, FLAC, OGG and AAC, rips CDs, runs batch jobs and even has a command-line mode. It is the best no-cost choice for most people. The trade-off is fewer extras — no audio capture, lighter metadata editing and a plainer interface — and you maintain it yourself. For free, it is hard to beat.
Pros
- Completely free and open-source
- Batch conversion, CD ripping and CLI
- Cross-platform
Cons
- Fewer extras than paid tools
- No audio capture, lighter tag editing
- Plainer, less guided interface
4
Freemake Audio Converter
Windows · free / $9.95
Best for quick everyday conversions
Freemake is friendly and simple, converting between the common formats with a couple of clicks and handling batch lists. The catch is freemium: the free build adds Freemake branding to output and caps some features behind a paid pass, there is no CD ripping or scripting, and it is Windows-only. Fine for a casual MP3 here and there; not built for libraries or automation.
Pros
- Very easy interface
- Handles common formats in batch
- Free to start
Cons
- Branding and feature limits on the free tier
- No CD ripping or command line
- Windows only
5
Audacity
Windows / Mac / Linux · free
Best if you also need to edit
Audacity is a superb free waveform editor, and it can export to MP3, WAV, FLAC and OGG — but it is an editor, not a real batch converter. You open files one at a time; bulk jobs need fiddly macros, there is no CD ripping, and it is overkill for a straight format change. Reach for it to trim, mix or clean up a track, not to convert a folder of 200.
Pros
- Powerful free waveform editing
- Exports the common formats
- Cross-platform
Cons
- An editor, not a batch converter
- Bulk jobs need awkward macros
- No CD ripping

Online Audio Converter
Online · free / subscription
Best for a single quick file
A browser converter is handy for one stray track — MP3 to WAV or FLAC to MP3 in a couple of clicks, nothing to install. The trade-offs are real: every file is uploaded to a third-party server, there are size caps, true batch is limited, and removing limits needs a subscription. Convenient for a one-off; the wrong tool for a private library or bulk work.
Pros
- Nothing to install
- Very easy, works on any OS
- Fine for a single small file
Cons
- Files uploaded to the cloud
- Size limits and a paid subscription
- No real folder batch, ripping or scripting
How to convert audio (or a whole folder)
This is the exact workflow we used with the number-one tool. A single track takes under a minute; a folder of hundreds is one click more.
- Download and install Total Audio Converter. Grab the 79 MB installer from CoolUtils and run it. The 30-day trial needs no credit card or email.
- Add your files. Point it at a single track or select a whole folder — the file tree lets you tick exactly what to convert, or insert a CD to rip. Nothing is uploaded; everything stays on your PC.
- Pick the output format. Choose MP3, WAV, FLAC, OGG, AAC, WMA, APE or OPUS from the toolbar. Use the built-in player to preview a track before you commit.
- Set options. Adjust bitrate and sample rate, edit ID3 or Vorbis tags and album art, or split an APE/FLAC album by its CUE sheet — or just keep the defaults.
- Click Start. The whole batch converts at once and the originals are left untouched, with the source folder structure preserved in the output.
Automating it from the command line
The differentiator for power users: the command-line build converts without opening the window, so you can script it. A line like the one below, dropped in a .bat file and scheduled, turns every track in a folder into MP3 overnight.
AudioConverter.exe "C:\In\*.flac" "C:\Out" -mp3 -log log.txt
Just need a single quick conversion? Total Audio Converter handles the heavy library and CD-ripping work, but for a one-off track CoolUtils also offers
free online audio converters such as OGG to MP3. For everything offline, batch and private, the desktop app is the pick.
How we tested
We do not rank on spec sheets alone. Every tool ran the same five-part job on the same Windows 11 machine, using identical source files:
- Format swap — one FLAC converted to MP3 and back, checking bitrate, sample rate and tags.
- Folder batch — 50 tracks converted in a single run.
- CD ripping — an audio CD ripped to both FLAC and MP3.
- CUE splitting — an APE+CUE album split into clean per-track files.
- Automation — the same conversion driven from the command line or a macro.
Scores weight what matters for real conversion work: format coverage and audio quality (30%), batch and automation (30%), CD ripping, CUE splitting and metadata (20%), and price and privacy (20%). Pricing was checked on each vendor's site in June 2026.
Who needs a dedicated audio converter?
Anyone who works with audio at scale: a collector ripping CDs into a FLAC library, a podcaster batch-encoding episodes to MP3, a game developer turning WAV into OGG, or anyone splitting an APE+CUE album into tagged tracks. For all of those, the CoolUtils Total Audio Converter does the most for the least — one price, offline, scriptable. New to formats? Start with our audio formats guide.
Frequently asked questions
How do I convert FLAC to MP3 without losing the tags?
Install a desktop converter such as the CoolUtils Total Audio Converter, add your FLAC file, choose MP3 as the output, set the bitrate and click Start. It carries the ID3 and Vorbis tags and album art across automatically, so artist, title and cover art stay intact — a one-time $24.90 licence, no subscription.
Can I batch convert a whole folder of audio at once?
Yes. Total Audio Converter is built for batch work: point it at a folder, tick the tracks you want, pick an output format like MP3 or FLAC and convert them all in one run. The original folder structure is preserved, and it can also run from the command line for unattended jobs.
How do I rip a CD to MP3 or FLAC?
Insert the audio CD, open Total Audio Converter and it reads the CDA tracks directly. Choose FLAC for a lossless rip or MP3 for a compressed one, set the quality and convert. The whole disc rips in one pass, with track names and tags applied automatically.
How do I split an album by its CUE sheet?
Total Audio Converter reads the CUE sheet that accompanies a single APE or FLAC album file and splits it into clean per-track files on conversion. Each track keeps its title and number, so one big album image becomes a tidy, tagged set of songs.
Is there an audio converter with command-line or automation support?
Yes. Total Audio Converter ships a command-line build, so you can script conversions in a .bat file or a scheduled task and process folders automatically on a server — something online converters and editors like Audacity cannot do out of the box.
What is the difference between lossless and lossy, and which should I pick?
Lossless formats like FLAC, WAV and APE keep every bit of the original, ideal for archiving but large. Lossy formats like MP3, AAC and OGG shrink the file by discarding inaudible detail, ideal for phones and streaming. Total Audio Converter goes both ways and preserves your tags either direction, so you can keep a FLAC archive and export MP3 copies from it.
