Transform your HEIC files into GIF format instantly within your browser.
HEIC is Apple's file extension for images encoded under the High Efficiency Image File Format (HEIF) standard, using HEVC (H.265) compression. Apple made it the default photo format on iPhones starting with iOS 11, since it stores images at roughly half the file size of an equivalent-quality JPEG. As a container format, a single HEIC file can also bundle image bursts, depth data, or Live Photo sequences together. The main friction point is compatibility: older software, most Windows PCs, and many web platforms still can't open HEIC natively, which is the main reason people convert it to JPG.
GIF (Graphics Interchange Format) was introduced by CompuServe in 1987 as a platform-independent format for sharing color graphics over slow, modem-speed connections. It uses lossless LZW compression on indexed images limited to a palette of 256 colors, and its defining feature is native support for simple looping animation, storing several frames with their own timing directly inside one file. GIF also supports single-color binary transparency. Even though modern formats like WebP and AVIF now offer full-color animation with much better compression, GIF's near-universal support in browsers, chat apps, and social platforms keeps it firmly embedded in everyday web culture.
