Audiobook Converter Pro by indie4tune Software: is it worth buying?
If you have a shelf of DRM-free M4B audiobooks that only play nicely on a few devices, the annoyance is simple: your chapters, metadata, and file names get stuck inside a format that is not as portable as MP3 or FLAC. Audiobook Converter Pro by indie4tune Software is a free Windows installer aimed at that exact friction, turning M4B files into MP3, AAC, or FLAC while trying to keep chapter marks intact. It is worth a look if you want a lightweight converter for a personal library, especially when the base download costs nothing and the product page also describes a Pro upgrade for batch queues and parallel processing. The catch is that this is a small, focused utility, not an all-purpose media suite, so the real question is whether your M4B files are DRM-free and whether you need the Pro features or just single-file conversion.

What you’re actually buying
The core of this product is a Windows setup file, not a cloud account, browser extension, or subscription dashboard. You get a desktop app for taking M4B audiobook files and converting them into more portable audio formats. The product page emphasizes the free Windows setup file, MP3/AAC/FLAC output, quality settings up to 320kbps, and lossless FLAC for people who want to keep the sound as close to the source as possible.
For audiobook listeners, the most useful part is chapter-preserving conversion. A converted file that loses chapter marks becomes just a long audio blob, especially if you are moving files between devices, cloud storage, or players that handle MP3 and FLAC differently. If you want to jump to the right spot in a novel or nonfiction title, chapter accuracy is the difference between a practical converter and a basic audio re-encode.
The product page also draws a line between the free download and Pro upgrade options. Pro features include metadata-driven filename updates, naming templates, multi-file queues, folder recursion, parallel chapter and file conversion, and choosing output folders. If your library is dozens of titles, those batch features can matter a lot. For a single file or a small test batch, the free entry point may be enough to see whether the workflow fits your files.
Why it’s on our radar
The public page currently shows 0 ratings and no visible sales count. That means there is no strong public review trail to lean on yet. The free price makes Audiobook Converter Pro free download a low-risk way to test whether it handles your DRM-free M4B files the way you need.
What actually matters
- Confirm your M4B files are DRM-free. The product is described as a converter for DRM-free M4B audiobook files, not a DRM removal tool.
- Check that you are on Windows. The download is described as a Windows application and setup installer, so Mac users should verify the current Audiobook Converter Pro page before assuming compatibility.
- Decide whether you need Pro features. Batch conversion, parallel processing, metadata filename updates, and naming templates are presented as Pro capabilities, so a single-file conversion may be all you need from the free download.
- Verify the current version and file size. The download details reference a 1.0.5 setup file around 203 MB, so make sure the file you receive matches what you expect before running the installer.

FAQ
Is Audiobook Converter Pro available for Mac?
The product is described as a Windows application with a setup installer. I would not count on a Mac version unless the live page explicitly offers one.
Is Audiobook Converter Pro v1.1.8 the same as this download?
The download details reference a 1.0.5 setup file, so if you are hunting for a specific v1.1.8 build, verify the current version on the live page before installing.
Can you get free audio books on Audible with this tool?
No. This is a converter for DRM-free M4B files you already have. It does not provide free Audible titles, and it should not be used to bypass DRM or violate terms of service.
Bottom line
If you have DRM-free M4B audiobooks on Windows and want a free way to test MP3, AAC, or FLAC conversion with chapter marks intact, Audiobook Converter Pro is a reasonable utility to try. It is not a magic library manager, and the Pro features matter more if you have a large collection, but the free entry point is low-risk for a focused conversion job. See current options
