Why Convert HEIC to WebP?
HEIC files from iPhones offer excellent quality but aren't supported by web browsers — you can't display HEIC images directly on a website. WebP is the modern web standard for images, supported by all major browsers (Chrome, Firefox, Safari, Edge) and offering the best balance of quality and compression. Converting HEIC to WebP is the optimal path for publishing iPhone photos online: you get files that are typically 25-34% smaller than JPG equivalents while maintaining excellent visual quality. WebP also supports transparency, which JPG doesn't — useful if you're working with screenshots or edited images. FormatPic performs this conversion entirely in your browser, which means your personal iPhone photos never touch a remote server.
HEIC vs WebP: Technical Differences
HEIC uses HEVC (H.265) codec achieving ~50% better compression than JPEG. WebP uses the VP8 codec (lossy) or predictive coding (lossless) achieving ~25-34% better compression than JPEG. Both formats are more efficient than JPEG, but HEIC has virtually no browser support while WebP has ~97% global browser support. For web publishing, WebP is the clear choice. File sizes when converting HEIC to WebP are comparable, with WebP sometimes producing slightly larger files — but the gain is universal web compatibility.
