Transform your HEIC files into WEBP 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.
WebP is a modern image format developed by Google and released in 2010, built on the intra-frame coding of the VP8 video codec. It supports both lossy and lossless compression in the same container, along with alpha transparency and simple animation, covering roughly the combined use cases of JPG, PNG, and GIF in a single format. In practice, WebP files are typically 25-35% smaller than a comparable JPEG or PNG at similar visual quality, which is why it has become a common recommendation for speeding up websites and improving Core Web Vitals scores.
