JPC to CUR Converter
Processing entirely on your device — large files may take a moment.
JPC is the raw JPEG 2000 code stream — the same wavelet-compressed image data as JP2 without the container box. Common in broadcast and archival pipelines that stream codestreams directly. Converting CUR to PNG lets you view and reuse cursor graphics in design tools.
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 JPC compares to CUR
| JPC | CUR | |
|---|---|---|
| Compression | Wavelet (lossy + lossless) | BMP/PNG members (as ICO) |
| Transparency | Supported | Supported |
| Animation | Not supported | No (that is .ani) |
| Metadata | None (bare codestream) | Hotspot coordinates |
| Best for | Broadcast streams, archival pipelines | Windows cursors and UI assets |

About the JPC format
JPC is JPEG 2000 stripped to its bare codestream: the same wavelet-compressed image data as JP2, minus the container boxes that give JP2 its metadata, color profiles and file signature. Broadcast and archival systems that stream codestreams directly (rather than storing boxed files) work with JPC.
Because there is no container, JPC carries no thumbnail, no EXIF and no declared colorspace — players must probe the codestream header itself. Converting JPC into JP2 restores a full container; converting to JPG or PNG produces an instantly viewable copy.
+Strengths
- ✓Wavelet compression, better per-byte quality than JPG
- ✓True lossless mode available
- ✓Streamable — no container parsing needed
!Limitations
- −No metadata, color profile or thumbnail
- −Browsers cannot open it at all
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
Why convert JPC to CUR?
There is a concrete reason this conversion exists: No metadata, color profile or thumbnail CUR sidesteps that — Windows cursor standard If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this JPC to CUR 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 JPC to CUR?
No — CUR is a lossless format, so every pixel of the converted image matches your original JPC file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several JPC 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 JPC files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
