About the HEIC / HEIF & PNG Formats
HEIC / HEIF (High Efficiency Image File Format)
HEIC is the file format name Apple chose for the new HEIF standard. It uses advanced compression algorithms to store high-quality images in half the file size of a JPG.
- About 50% smaller file size than JPEG with the same quality
- Supports auxiliary data like depth maps, bursts, and live photos
- Supports 16-bit color depth (compared to JPG's 8-bit)
- Limited native browser compatibility (does not render directly in Chrome or Firefox)
- Proprietary patent issues limit open adoption
- Needs conversion before uploading to many web applications
PNG (Portable Network Graphics)
PNG is a raster-graphics file-format that supports lossless data compression. It was created as an improved, non-patented replacement for Graphics Interchange Format (GIF).
- Lossless compression retains perfect quality
- Supports full transparency (alpha channel)
- Excellent for graphics, text, and line art
- Significantly larger file sizes than JPG for photographs
- Does not support animation (unlike APNG which is less compatible)
- Not optimized for print graphics (no CMYK support)

Frequently Asked Questions
Is there any compression benefit to converting HEIC to PNG?
No. HEIC has superior compression to PNG. Converting to PNG will significantly increase the file size, but it makes the file compatible with all image editor programs.
