HEIF vs PNG
A detailed comparison of HEIF Image and PNG Image — file size, quality, compatibility, and which format to choose for your workflow.
HEIF Image
Raster & Vector ImagesHEIF (High Efficiency Image File Format) is the container format behind HEIC. It supports advanced features like image sequences, depth maps, and HDR but has limited cross-platform support.
About HEIF filesPNG Image
Raster & Vector ImagesPNG is a lossless image format that supports transparency. It is ideal for graphics, logos, screenshots, and any image where preserving exact pixel data is important.
About PNG filesStrengths Comparison
HEIF Strengths
- ~50% smaller than JPEG at equivalent quality, with better detail retention.
- Container holds multi-image bursts, depth maps, and HDR data in one file.
- Supports 10 and 12-bit color, wide gamut, and HDR out of the box.
- Default iPhone camera format since 2017 — billions of files in existence.
PNG Strengths
- Lossless compression — every save preserves the original pixels perfectly.
- Full 8-bit alpha channel for smooth transparency.
- Excellent for text, UI screenshots, logos, and line art.
- Royalty-free and an ISO standard (ISO/IEC 15948).
- Supports 16-bit color depth for high-fidelity work.
Limitations
HEIF Limitations
- HEVC codec inside .heic is patent-encumbered — licensing fees steered the web toward AVIF.
- Windows, Android, and most email clients needed plugins or recent updates to open HEIC.
- Encoding is CPU-intensive on older hardware.
- Fragmented ecosystem — the same file extension (.heif) can hold incompatible codecs.
PNG Limitations
- Much larger than JPEG for photographs (no perceptual compression).
- No native animation in most software (APNG support is inconsistent).
- No CMYK support — web and screen only, not print.
- Metadata capabilities are less rich than JPEG's EXIF.

Frequently Asked Questions
HEIF (High Efficiency Image File Format) is a container format based on HEVC compression, standardized by MPEG in 2015. It can store still images, image sequences, and auxiliary data like depth maps. HEIC is the most common HEIF variant.

HEIF is the container format specification, while HEIC is a specific implementation using HEVC codec for compression. In practice, iPhone photos labeled as HEIC are HEIF files. The terms are often used interchangeably for Apple device photos.
