What is BPG?

Better Portable Graphics (BPG) is a modern image format based on HEVC video compression, offering excellent compression efficiency.

What is CUR?

Windows Cursor (CUR) is the mouse cursor format for Windows, supporting static and animated pointers with hotspot definitions.

When Should You Use BPG vs CUR?

BPG vs CUR: Key Differences

• •The core technical difference: BPG relies on lossy compression whereas CUR uses lossless compression.
• •Moving from BPG (lossless) to CUR (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: CUR supports transparency, so alpha information is preserved during conversion.
• •File sizes: BPG files typically range 30-50% smaller than JPEG at same quality and CUR files Very small, typically under 50KB.
• •Use case fit: BPG targets web images with superior compression and CUR targets windows ui cursors, mouse pointer graphics — your choice depends on which workflow stage you are serving.

Advantages of BPG

• ✓BPG applies lossy compression specifically calibrated for Web images with superior compression.
• ✓BPG enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓BPG delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find BPG support built into virtually every tool that handles Web images with superior compression — no plugins or converters needed.

Advantages of CUR

• ✓The lossless nature of CUR means file sizes stay reasonable while handling Windows UI cursors, mouse pointer graphics efficiently.
• ✓From mobile devices to enterprise servers, CUR is recognized and supported everywhere.
• ✓The trade-off for CUR's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓CUR is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Common Use Cases for BPG to CUR Conversion

• Graphic design projects
• E-commerce product images
• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations
• Mobile app UI assets

Industry Applications

Best Practices for BPG to CUR Conversion

• →Before converting BPG to CUR, decide whether you need maximum quality or smallest file size — this determines which format truly fits
• →Save a master copy in a lossless format before converting to CUR — you cannot recover detail lost during lossy compression
• →Check the color profile: BPG images may use a wider gamut than CUR supports, causing a visible shift after conversion
• →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
• →Run a single test conversion first to verify quality meets your standards
• →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting BPG to CUR Conversion

• !Converting BPG to CUR gives blurry output → increase the quality setting before conversion
• !Colors look different in CUR than BPG → check color profile mismatch (sRGB vs Adobe RGB)
• !File size changed more than expected → CUR uses different compression, file size differences of 2-5x are normal
• !Transparent areas in BPG turned white in CUR → CUR may not support transparency
