CUR to TXZ Converter
Processing entirely on your device — large files may take a moment.
Convert TXZ exactly like TAR.XZ. If your files are still in CUR format, this page is the shortcut: CUR is the Windows cursor format — structurally an ICO file with a hotspot, holding small bitmap cursor images.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How CUR compares to TXZ
| CUR | TXZ | |
|---|---|---|
| Compression | BMP/PNG members (as ICO) | XZ / LZMA2 |
| Best for | Windows cursors and UI assets | Source releases, Linux packages |

About the CUR format
CUR is the Windows cursor file: structurally identical to ICO (several small bitmap sizes bundled), with the addition of a hotspot coordinate that marks which pixel is the pointer's tip. Windows ships most of its system cursors as CUR files.
Designers customizing cursors or extracting UI assets meet CUR files that no modern image tool opens. Converting to PNG (the largest embedded size) makes them editable, viewable and reusable in web apps that implement custom cursors.
+Strengths
- ✓Windows cursor standard
- ✓Multiple sizes in one file
- ✓Hotspot data travels with the image
!Limitations
- −Tiny sizes only (usually ≤48px)
- −Meaningless outside cursor use
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 CUR to TXZ?
Think of it as moving your file to the container that fits the job. Tiny sizes only (usually ≤48px) TXZ works differently: Best compression ratio of the tar family If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this CUR 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.
Will I lose quality converting CUR to TXZ?
No — TXZ is a lossless format, so every pixel of the converted image matches your original CUR file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several CUR files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your CUR files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
