QCP to TXZ Converter
Processing entirely on your device — large files may take a moment.

Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

ffmpeg decodes it natively inside your browser — the audio track is re-encoded to your chosen format with nothing ever uploaded.
+Strengths

- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Legacy niche format
- −Modern tools rarely open it
- −Keep the original for archival round-trips
About the TXZ format
TAR.XZ pairs the tar container with XZ (LZMA2) compression — the highest-ratio member of the tar family and the de-facto release format of modern Linux distributions. The same source tree that lands 5% smaller than TAR.BZ2 and 20% smaller than TAR.GZ is why kernel.org and GNU mirrors standardised on it.
The trade is CPU time: XZ compresses slow (dictionary sizes up to 64 MB) but decompresses fast, which makes it ideal for one-time releases that get downloaded millions of times. When you need speed instead, TAR.GZ or TAR.ZSTD are the neighbouring picks.
+Strengths
- ✓Best compression ratio of the tar family
- ✓Standard release artifact of Linux distros
- ✓Fast decompression despite slow compression
!Limitations
- −Compression is CPU-heavy and single-threaded by default
- −Larger toolchain footprint than gzip on tiny systems
Why convert QCP to TXZ?
Converting makes sense where the strengths of TXZ meet what QCP cannot give you. Best compression ratio of the tar family Meanwhile Legacy niche format One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this QCP to TXZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for QCP to TXZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Will converting QCP to TXZ reduce audio quality?
If TXZ is lossless, the output contains everything the QCP file contains — no further loss is added. If TXZ is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
