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 WEBP file?

WebP is a raster graphics file format developed by Google specifically for web optimization, utilizing the Resource Interchange File Format (RIFF) container. It employs predictive coding based on the VP8 video codec for lossy compression and the LZ77 algorithm with entropy coding for lossless compression. WebP supports transparency (alpha channel) in both lossy and lossless modes, as well as animation, often achieving file sizes 26-34% smaller than comparable JPEG or PNG files while maintaining high structural similarity (SSIM) index scores.

How to open a WEBP file

WebP is natively supported by all modern web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari. For offline viewing, Windows 10 and 11 support WebP via the Photos app (often requiring the Webp Image Extensions package), while macOS users can view them in Preview (macOS Big Sur and later). Legacy systems or incompatible editors require conversion tools or third-party viewers like IrfanView to render the image data.
