CUR to TBZ2 Converter
Processing entirely on your device — large files may take a moment.
CUR is the Windows cursor format — structurally an ICO file with a hotspot, holding small bitmap cursor images. Convert TBZ2 exactly like TAR.BZ2.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How CUR compares to TBZ2
| CUR | TBZ2 | |
|---|---|---|
| Compression | BMP/PNG members (as ICO) | Bzip2 (block-sorting) |
| Best for | Windows cursors and UI assets | Legacy release artifacts |

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 TBZ2 format
TAR.BZ2 pairs the tar container with bzip2 compression — the classic release artifact of the 2000s Unix world. Bzip2's block-sorting algorithm compresses text and source trees noticeably tighter than gzip, which is why distribution mirrors and source releases favoured it for years.
Today it has largely ceded the top spot to TAR.XZ (smaller) and tar.gz (faster), but countless build scripts, mirrors and legacy toolchains still expect the exact .tar.bz2 artifact — and producing it is a matter of running the tar through a bzip2 encoder.
+Strengths
- ✓Tighter than gzip on text and source trees
- ✓Classic, universally supported on Unix-like systems
- ✓Deterministic, well-understood artifact for releases
!Limitations
- −Slow compression compared to gzip/zstd
- −Larger than TAR.XZ for the same content
- −Single stream — no random file access
Why convert CUR to TBZ2?
Converting makes sense where the strengths of TBZ2 meet what CUR cannot give you. Tighter than gzip on text and source trees Meanwhile Tiny sizes only (usually ≤48px) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this CUR to TBZ2 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 TBZ2?
No — TBZ2 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.
Will transparent areas survive the conversion to TBZ2?
Transparency is kept whenever TBZ2 actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
