What is BPG?

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

What is ARW?

Sony Alpha Raw (ARW) is Sony's proprietary raw image format containing unprocessed sensor data from Sony Alpha and Cyber-shot cameras.

When Should You Use BPG vs ARW?

BPG vs ARW: Key Differences

• •The core technical difference: BPG relies on lossy compression whereas ARW uses lossless compression.
• •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
• •Alpha channel support: ARW lacks transparency support.
• •Storage footprint: 30-50% smaller than JPEG at same quality for BPG vs 20-40MB per photo for ARW.
• •Use case fit: BPG targets web images with superior compression and ARW targets sony camera post-processing, professional editing — 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 ARW

• ✓ARW applies lossless compression specifically calibrated for Sony camera post-processing, professional editing.
• ✓ARW enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓ARW guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find ARW support built into virtually every tool that handles Sony camera post-processing, professional editing — no plugins or converters needed.

Common Use Cases for BPG to ARW Conversion

• Video thumbnail creation
• Certificate and badge design
• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing

Industry Applications

Best Practices for BPG to ARW Conversion

• →Before converting BPG to ARW, 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 ARW — you cannot recover detail lost during lossy compression
• →Check the color profile: BPG images may use a wider gamut than ARW 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 ARW Conversion

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