What is a HEIC file?

HEIC (High Efficiency Image Container) is the file extension used for images stored in the High Efficiency Image File Format (HEIF) specifically when encoded with the High Efficiency Video Coding (HEVC/H.265) standard. Adopted by Apple in iOS 11 and macOS High Sierra, it encapsulates single images or image sequences using the ISO Base Media File Format (ISOBMFF). It offers superior compression ratios-typically 50% smaller than equivalent JPEGs-while supporting 16-bit color depth, transparency (alpha channels), and non-destructive editing instructions.

How to open a HEIC file

Native support is available on macOS (High Sierra and later), iOS 11+, and Windows 10/11 (provided the HEIF Image Extensions and HEVC Video Extensions are installed from the Microsoft Store). Android 9 (Pie) and later also support the format natively. For older systems or non-compatible software, users often require conversion tools like iMazing HEIC Converter or must use viewers like VLC Media Player and GIMP, which have integrated HEIC decoding libraries.

What is a PNG file?

Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression, created as a patent-free replacement for the Graphics Interchange Format (GIF). Standardized as ISO/IEC 15948:2004, PNG utilizes the DEFLATE compression algorithm (a combination of LZ77 and Huffman coding) and supports palette-based images, grayscale, and full-color non-palette-based RGB/RGBA images. A defining feature is its alpha channel support, allowing for variable transparency levels, unlike the binary transparency of GIF. It does not support animation but offers gamma correction and interlacing via the Adam7 algorithm.

How to open a PNG file

PNG files possess near-universal compatibility across all major operating systems (Windows, macOS, Linux, Android, iOS) and web browsers (Chrome, Firefox, Safari) without requiring additional software. Default image viewers such as Microsoft Photos, Apple Preview, and virtually all graphics editing software including GIMP, Adobe Photoshop, and Paint.NET natively handle the format.
