What is EXR?

OpenEXR is a high-dynamic-range raster image format developed by Industrial Light & Magic for the VFX and film industry.

What is BPG?

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

When Should You Use EXR vs BPG?

EXR vs BPG: Key Differences

• •EXR uses lossless compression while BPG uses lossy compression — this is the fundamental technical difference between the two formats.
• •Moving from EXR (lossy) to BPG (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: BPG does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: EXR files typically range 15-100MB for high-res HDR frames and BPG files 30-50% smaller than JPEG at same quality.
• •EXR is optimized for vfx, 3d rendering, hdr imaging while BPG is designed for web images with superior compression — choose based on your specific workflow needs

Advantages of EXR

• ✓At its core, EXR relies on lossless encoding — a design choice that makes it perfect for VFX, 3D rendering, HDR imaging.
• ✓You won't run into compatibility issues with EXR — it's a universal standard across platforms.
• ✓File size management with EXR: larger files guaranteed to match the original exactly.
• ✓Every major application in the VFX, 3D rendering, HDR imaging space supports EXR natively.

Advantages of BPG

• ✓At its core, BPG relies on lossy encoding — a design choice that makes it perfect for Web images with superior compression.
• ✓You won't run into compatibility issues with BPG — it's a universal standard across platforms.
• ✓File size management with BPG: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Web images with superior compression space supports BPG natively.

Common Use Cases for EXR to BPG Conversion

• E-commerce product images
• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations
• Mobile app UI assets
• Product photography for marketplaces

Industry Applications

Best Practices for EXR to BPG Conversion

• →When converting EXR to BPG, check whether BPG supports transparency — if not, your transparent areas will be filled with a solid color
• →Use BPG for maximum quality archival and EXR for smaller file sizes when quality is less critical
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting EXR to BPG Conversion

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