CUR to QOI 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. QOI is popular with hobbyist engines and emulators; convert to PNG to view it anywhere.
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 QOI
| CUR | QOI | |
|---|---|---|
| Compression | BMP/PNG members (as ICO) | Lossless (RLE/delta) |
| Transparency | Supported | Supported |
| Animation | No (that is .ani) | Not supported |
| Metadata | Hotspot coordinates | None |
| Best for | Windows cursors and UI assets | Hobby engines, lossless simplicity |

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 QOI format
QOI (Quite OK Image, 2021) is a lossless format defined in one short specification document: a stream of simple run-length and delta ops over linear pixels. An encoder fits in 300 lines, decodes faster than PNG, and compresses comparably for photographic content.
It has found a home in emulators, demoscene projects and hobby engines — anywhere people want images without a codec dependency. Viewers rarely support it, so converting QOI to PNG is the way to bring these files into normal tools.
+ Strengths
- ✓Radically simple spec (~200 lines)
- ✓Lossless with fast decode
- ✓No patent or licensing questions
! Limitations
- −Almost no viewer support
- −Larger than modern codecs for many images
Why convert CUR to QOI?
There is a concrete reason this conversion exists: Tiny sizes only (usually ≤48px) QOI sidesteps that — Radically simple spec (~200 lines) If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this CUR to QOI 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 QOI?
No — QOI 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.
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.
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.
