Convert HEIC to WebP Online

HEIC and WebP are both modern, highly efficient image formats - But they live in different worlds. HEIC is Apple's camera capture format; no web browser will display it in an tag. WebP is Google's web delivery format with over 97% global browser support. Converting HEIC to WebP is the natural step when iPhone photos need to be published on a website: you keep small, efficient files while gaining universal browser compatibility.

Because both formats use sophisticated modern compression, the size change is modest - Unlike converting to JPG or PNG, a WebP is typically only slightly larger than the source HEIC at equivalent visual quality. WebP also supports alpha transparency, so any transparency in the HEIC carries across. For web developers, small WebP files translate directly into better Core Web Vitals scores - Particularly Largest Contentful Paint (LCP) - And lower bandwidth costs.

As of 2025, WebP is supported in all versions of Chrome, Firefox, Edge, Opera, and Safari 14+. That makes WebP the safe choice for serving iPhone photography on the web, where uploading raw HEIC files would simply fail to render for every visitor.

WebP was released by Google in September 2010, derived from the VP8 video codec the company acquired with On2 Technologies earlier that year. The initial spec only supported lossy compression; lossless and alpha-channel support were added in 2011, and animated WebP arrived in 2012. Adoption stalled until Apple finally shipped WebP support in Safari 14 (September 2020) and macOS Big Sur, which made WebP viable as a primary web format. It is the natural delivery partner for HEIC: both are video-codec-derived image formats of the mid-2010s, but WebP won the browser while HEIC won the camera roll - so iPhone photos headed for a website almost always make this exact hop.

Web browsers cannot be relied on to display HEIC - Uploading an iPhone photo to a website usually means converting it first. WebP is the web-native counterpart to HEIC: a modern, efficient format supported by Chrome, Firefox, Edge, and Safari 14+. Converting HEIC to WebP is the direct path from an iPhone camera roll to fast-loading web pages without giving up the small-file advantage.

Bloggers, e-commerce sellers, and content teams who shoot product photos and article images on iPhone convert to WebP before uploading to their CMS. The result keeps page payloads small, improves Core Web Vitals scores, and avoids the outright HEIC rejection that WordPress, Shopify, and most upload forms still enforce.

Because both formats use modern lossy codecs, the size change is modest - Unlike converting to JPG, where files often grow. Converting at 80–90% quality preserves the visual quality of the original while producing a file every browser can render natively.
