Understanding HEIC and FLIF File Formats
What is HEIC File Format
HEIC (High Efficiency Image Container) is a modern image format widely used by Apple devices. It uses HEVC compression to offer high-quality images at significantly reduced file sizes whilesupporting features like 16-bit color depth and transparency. HEIC can store multiple images in one file, great for Live Photos and burst shots.
What is FLIF File Format
FLIF (Free Lossless Image Format) is an advanced, open-source image format designed for efficient lossless compression. FLIF offers better compression ratios than traditional lossless formats such as PNG and TIFF, achieving smaller file sizes while preserving perfect image quality. Although development on FLIF has slowed, it remains one of the most efficient lossless image codecs for quality preservation.
Why Convert HEIC to FLIF?
- Superior Lossless Compression: FLIF achieves much smaller file sizes than PNG or TIFF while maintaining perfect image fidelity.
- Preserves High Image Quality: FLIF retains all original image data without any loss.
- Wide Color Support: Supports up to 16-bit color depth for crisp, vibrant images.
- Progressive Loading: FLIF supports progressive decoding, showing images in increasing detail as data downloads.
- Open and Patent-Free: FLIF is free to use without licensing fees or restrictions.
- Ideal for Archiving: Best for users wanting to archive images losslessly with optimal storage efficiency.
When Should You Convert HEIC Files to FLIF?
- When needing efficient, lossless compression with maximum image fidelity.
- For archiving photos digitally with minimal storage usage.
- When sharing images requiring progressive loading on slow or unreliable internet.
- To convert HEIC photos for professional workflows requiring lossless formats.
- When preferring open, royalty-free image formats for compatibility and longevity.
HEIC to FLIF File Comparison
Feature | HEIC (High Efficiency Image Container) | FLIF (Free Lossless Image Format) | Winner |
---|---|---|---|
File Size | Highly efficient; lossy or lossless HEVC compression | Highly compact for lossless images, outperforms PNG and others | Depends |
Compression | HEVC/H.265-based; both lossy and lossless, up to 16-bit, HDR, alpha, animation | Progressive MANIAC-based; strictly lossless, up to 16-bit, alpha, animation | FLIF |
Web/App Support | Limited browser and cross-platform support, best in Apple ecosystem | No native browser support; rarely supported in apps, format no longer maintained | HEIC |
Quality & Bit Depth | Up to 16-bit color, full HDR, lossy or lossless, alpha, animation | Always lossless, up to 16-bit/channel RGBA, full fidelity | FLIF |
Transparency | Full alpha channel and overlays | Full alpha; lossless preservation of smooth gradients | Tie |
Animation | Multi-image files, live images, burst/animated sequences | Lossless multi-frame animation, but rarely supported in tooling | HEIC |
Progressive/Interlacing | No true progressive/interlaced decoding; streaming possible | Progressive by design—efficient loading, any partial file is a valid preview | FLIF |
Use Cases | Mobile imaging, Apple ecosystem, web (with conversion), HDR, live/burst | Long-term lossless archival, storage efficiency, pro editing | Depends |
Tooling & Adoption | Broad mobile/Apple support, conversion tools exist | Niche; not actively developed, some open source tools available | HEIC |

Before & After Example
Before Conversion (HEIC):
HEIC images offer efficient lossy compression suitable for everyday photography with great quality and smaller file sizes.
After Conversion (FLIF):
Converting to FLIF results in a lossless, highly compressed image with perfect quality preservation, excellent for archiving or professional uses. FLIF files balance smaller sizes than traditional lossless formats while retaining every pixel detail, unlike HEIC’s lossy compression that trades off some information for size savings.
