HEIC is the default photo format on iPhone since iOS 11 — great for storage, poorly supported outside Apple devices. Converting to WEBP happens instantly, right in your browser. WEBP typically produces 25–35% smaller files than JPG or PNG at similar visual quality.
iPhones save photos as HEIC by default, so moving them to a Windows PC, an older app, or a web upload form often hits a compatibility wall without any clear explanation why. Converting to WEBP gets you a strong balance of small file size and high visual quality for the web — done instantly, for free, without installing anything or creating an account.
Quick verdict: Pick HEIC for iPhone photos, Apple ecosystem, WEBP for modern web images, faster page loads.
.heic, .heif.webpimage/heicimage/webpConverting your HEIC file to WEBP happens in three steps, entirely on your device: your browser reads the HEIC file into memory, decodes and re-encodes it as WEBP using built-in browser technology (Canvas and WebAssembly), and hands you the finished file as a direct download.
At no point does the file get sent to a server. There’s no upload step to intercept, no account that could be breached, and nothing stored after you close the tab — the conversion simply couldn’t leak your file even if something went wrong, because it never left your browser in the first place.
