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 AVIF?

AVIF (AV1 Image File Format) is a new image format based on the AV1 video codec. It provides outstanding image quality and compression efficiency.

When Should You Use EXR vs AVIF?

EXR vs AVIF: Key Differences

• •The core technical difference: EXR relies on lossless compression whereas AVIF uses lossy compression.
• •Moving from EXR (lossy) to AVIF (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: AVIF does not support alpha channels — transparent areas in the source will become opaque.
• •EXR files are typically 15-100MB for high-res HDR frames while AVIF files range 40-50% smaller than JPEG/PNG
• •EXR is optimized for vfx, 3d rendering, hdr imaging while AVIF is designed for modern web, next-generation web applications — 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 AVIF

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

Common Use Cases for EXR to AVIF Conversion

• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing
• Graphic design projects
• E-commerce product images

Industry Applications

Best Practices for EXR to AVIF Conversion

• →When converting EXR to AVIF, check whether AVIF supports transparency — if not, your transparent areas will be filled with a solid color
• →Use AVIF 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 AVIF Conversion

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