HEIC to WebP Converter: Free & Private
You are putting iPhone photos on a website and you care about how fast it loads. Convert it here, in your browser, with nothing uploaded anywhere.
Why convert HEIC to WebP?
WebP is the practical default for web imagery in 2026: it is supported by every browser still receiving security updates, it beats JPG by roughly 25-35% at matched visual quality, and unlike AVIF it encodes fast enough that a large batch does not tie up your machine. Converting straight from HEIC skips the lossy JPG middle step that most workflows accidentally include.
The catch worth knowing about
Going HEIC → JPG → WebP re-compresses the photo twice and bakes the first round of JPG artefacts permanently into the WebP. Converting HEIC directly to WebP, as this page does, decodes once and encodes once.
One tip before you start
WebP keeps transparency, so it also works for exported graphics, but a photo straight off an iPhone has no alpha channel to preserve.
HEIC vs WebP, quick comparison
