What is AVIFS?

AVIF Sequence, animated AVIF image format for modern web — stored as image/avif-sequence — uses lossy encoding to handle modern web animations, high-efficiency image sequences. Typical file sizes: varies by content.

What is RW2?

Panasonic Raw v2 (RW2) contains raw sensor data from Panasonic Lumix digital cameras.

When Should You Use AVIFS vs RW2?

AVIFS vs RW2: Key Differences

• •The core technical difference: AVIFS relies on lossy compression whereas RW2 uses lossless compression.
• •Moving from AVIFS (lossless) to RW2 (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: RW2 supports transparency, so alpha information is preserved during conversion.
• •File sizes: AVIFS files typically range N/A and RW2 files 20-45MB per photo.
• •AVIFS is optimized for modern web animations, high-efficiency image sequences while RW2 is designed for panasonic/lumix camera raw editing — choose based on your specific workflow needs

Advantages of AVIFS

• ✓AVIFS applies lossy compression specifically calibrated for Modern web animations, high-efficiency image sequences.
• ✓AVIFS enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓AVIFS delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find AVIFS support built into virtually every tool that handles Modern web animations, high-efficiency image sequences — no plugins or converters needed.

Advantages of RW2

• ✓RW2 uses lossless compression tailored for Panasonic/Lumix camera raw editing.
• ✓RW2 is supported natively on virtually every device, browser, and operating system.
• ✓RW2 files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓RW2 integrates seamlessly with all major creative tools and workflows.

Industry Applications

Best Practices for AVIFS to RW2 Conversion

• →When converting AVIFS to RW2, check whether RW2 supports transparency — if not, your transparent areas will be filled with a solid color
• →Use RW2 for maximum quality archival and AVIFS 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 AVIFS to RW2 Conversion

• !Converting AVIFS to RW2 gives blurry output → increase the quality setting before conversion
• !Colors look different in RW2 than AVIFS → check color profile mismatch (sRGB vs Adobe RGB)
• !File size changed more than expected → RW2 uses different compression, file size differences of 2-5x are normal
• !Transparent areas in AVIFS turned white in RW2 → RW2 may not support transparency
