What is QOI?

QOI (Quite OK Image) is a lossless image format designed for simplicity and performance. It offers fast encoding and decoding with compression ratios comparable to PNG, making it ideal for game development and real-time applications.

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 QOI vs AVIF?

QOI vs AVIF: Key Differences

• •The core technical difference: QOI relies on lossless compression whereas AVIF uses lossy compression.
• •Moving from QOI (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.
• •QOI files are typically Similar to PNG, typically 20-30% smaller than uncompressed data while AVIF files range 40-50% smaller than JPEG/PNG
• •QOI is optimized for game development, pixel art, embedded systems, quick texture loading while AVIF is designed for modern web, next-generation web applications — choose based on your specific workflow needs

Advantages of QOI

• ✓At its core, QOI relies on lossless encoding — a design choice that makes it perfect for Game development, pixel art, embedded systems, quick texture loading.
• ✓You won't run into compatibility issues with QOI — it's a universal standard across platforms.
• ✓File size management with QOI: larger files guaranteed to match the original exactly.
• ✓Every major application in the Game development, pixel art, embedded systems, quick texture loading space supports QOI natively.

Advantages of AVIF

• ✓AVIF uses lossy compression tailored for Modern web, next-generation web applications.
• ✓AVIF is supported natively on virtually every device, browser, and operating system.
• ✓AVIF files are compact and quick to transfer, even over slow connections.
• ✓AVIF integrates seamlessly with all major web development tools and workflows.

Troubleshooting QOI to AVIF Conversion

• !Converting QOI to AVIF gives blurry output → increase the quality setting before conversion
• !Colors look different in AVIF than QOI → 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 QOI turned white in AVIF → AVIF may not support transparency
