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 BPG?

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

When Should You Use QOI vs BPG?

Use QOI When...

Reach for QOI when your priority is game development, pixel art, embedded systems, quick texture loading — its uncompromising quality ensures every detail is preserved.

Use BPG When...

Reach for BPG when your priority is web images with superior compression — its efficient compression makes sharing fast and storage minimal.

QOI vs BPG: Key Differences

  • •QOI uses lossless compression while BPG uses lossy compression — this is the fundamental technical difference between the two formats.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •Alpha channel support: BPG handles transparency, so semi-transparent pixels from the source will be lost.
  • •File sizes: QOI files typically range Similar to PNG, typically 20-30% smaller than uncompressed data and BPG files 30-50% smaller than JPEG at same quality.
  • •QOI is optimized for game development, pixel art, embedded systems, quick texture loading while BPG is designed for web images with superior compression — choose based on your specific workflow needs

Troubleshooting QOI 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 QOI 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
