Understanding AVIF and FLIF File Formats

What is AVIF File Format

AVIF (AV1 Image File Format) is a modern, highly efficient compressed image format based on the AV1 codec. It supports both lossy and lossless compression, HDR, transparency, and wide color gamuts, making it ideal for web and mobile use with excellent quality at reduced file sizes.

What is FLIF File Format

FLIF (Free Lossless Image Format) is a lossless image format designed to outperform traditional formats like PNG, lossless WebP, and lossless JPEG 2000 in compression efficiency. It supports progressive decoding, meaning even partial files can display a reasonable preview, and is optimized for high-quality lossless image storage.

Why Convert AVIF to FLIF?

Lossless Compression: FLIF offers superior lossless compression, ensuring zero quality loss when compared to compressed AVIF files.
Progressive Decoding: FLIF supports progressive loading, allowing partial image previews, beneficial for slow networks.
Better Compression Ratios: FLIF often achieves smaller file sizes than other lossless formats, saving storage without quality compromise.
Preserve Image Integrity: Ideal for archiving or professional work where image quality cannot be sacrificed.
Open Source and License Friendly: FLIF is developed as open-source software, free to use and redistribute.

When Should You Convert AVIF Files to FLIF?

When lossless image quality is required beyond AVIF’s lossy compression.
For archival or professional imaging where no quality loss is acceptable.
To enable progressive image loading in environments with limited bandwidth.
When maximum compression efficiency combined with lossless fidelity is desired.
For workflows preferring open-source, royalty-free lossless formats.
