When Should You Use BPG vs ICO?

BPG vs ICO: Key Differences

• •BPG and ICO diverge on compression: lossy compression for the source, lossless compression for the target.
• •Moving from BPG (lossless) to ICO (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Alpha channel support: ICO handles transparency.
• •Storage footprint: 30-50% smaller than JPEG at same quality for BPG vs 1-16KB for ICO.
• •Use case fit: BPG targets web images with superior compression and ICO targets favicons, application icons, platform-specific assets — your choice depends on which workflow stage you are serving.

Advantages of BPG

• ✓The lossy nature of BPG means file sizes stay reasonable while handling Web images with superior compression efficiently.
• ✓From mobile devices to enterprise servers, BPG is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using BPG thanks to its efficient compression.
• ✓BPG is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of ICO

• ✓At its core, ICO relies on lossless encoding — a design choice that makes it perfect for Favicons, application icons, platform-specific assets.
• ✓You won't run into compatibility issues with ICO — it's a universal standard across platforms.
• ✓File size management with ICO: larger files guaranteed to match the original exactly.
• ✓Every major application in the Favicons, application icons, platform-specific assets space supports ICO natively.

Troubleshooting BPG to ICO Conversion

• !ICO shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted ICO image looks washed out → the source BPG likely uses a wider color space than ICO supports
• !ICO file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted ICO looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
