About formats

JPEG is one of the most widely used image formats in computing, standardized by the Joint Photographic Experts Group and published as ISO/IEC 10918-1 in September 1992. The .jpeg extension is functionally identical to .jpg — both contain the same JFIF or Exif-wrapped JPEG compressed image data. The format applies lossy compression using the discrete cosine transform (DCT): images are divided into 8x8 pixel blocks, transformed into frequency coefficients, quantized to discard visually less significant information, and entropy-coded for storage. The quality-to-size tradeoff is user-selectable, with typical settings producing files 10-20 times smaller than uncompressed originals at visually acceptable quality. JPEG supports 8-bit grayscale and 24-bit color, with Exif metadata carrying camera settings, GPS coordinates, timestamps, and thumbnails. One advantage is absolute universality — JPEG is readable by every image viewer, web browser, operating system, camera, phone, and printer manufactured in the past three decades, making it the safest format for sharing photographic images with any recipient. The efficient compression of continuous-tone photographic content is another core strength: JPEG consistently produces compact files from camera sensors and real-world scenes where subtle color gradients dominate. While newer formats like WebP and AVIF achieve better compression ratios, JPEG's installed base is so vast that it remains the default output of digital cameras and the most common image format on the web.

CUR is the cursor image format for Microsoft Windows, structurally nearly identical to the ICO (icon) format but with the addition of a hotspot coordinate that identifies the precise pixel position where mouse clicks register. Introduced with early Windows versions, CUR files use the same container structure as ICO: a directory header listing one or more image entries, each specifying dimensions and color depth, followed by the pixel data for each variant. Like ICO, a single CUR file can contain multiple images at different sizes and color depths, allowing Windows to select the most appropriate cursor image for the current display resolution and color settings. Image data within CUR files can be stored as BMP pixel arrays (for legacy compatibility) or as embedded PNG images (supported since Windows Vista) for alpha-blended cursors with smooth edges. The hotspot coordinate — the distinguishing feature separating CUR from ICO — is stored as an X,Y pair in the directory entry header, typically pointing to the tip of an arrow or the center of a crosshair. One advantage is multi-resolution packaging: a single CUR file provides appropriate cursor imagery across display densities from standard DPI to high-DPI screens. Native Windows integration is another strength — CUR files are loaded directly by the operating system for mouse cursor display without any third-party software. CUR files are used by application developers and theme creators to customize the pointing experience across Windows environments.

Frequently Asked Questions

Why convert JPEG to CUR?

CUR is the Windows cursor format. Converting your JPEG image creates a custom cursor you can use for Windows desktop themes and applications.

Which apps support CUR?

CUR opens in Windows natively, GIMP, IcoFX. Most platforms have at least one application that handles this format natively.

Can I batch convert JPEG to CUR?

Convertio handles batch conversions. Add multiple JPEG images at once and let the system convert them all to CUR in parallel for maximum efficiency.

What platforms does this converter support?

The converter works on any device with a browser — Windows, macOS, Linux, iOS, and Android. No app installation needed — everything runs in the cloud.

Is the conversion lossless?

The conversion retains image quality within the capabilities of CUR. Any format-specific limitations are inherent to the target, not the conversion process.
