How do I convert a HEIC photo to WebP?

Drag your .heic file onto the upload zone (or click to browse). The tool decodes it on your device and shows a preview with WebP pre-selected. Set the quality if you wish, then Export and Download. It is completely free and runs entirely in your browser — the photo is never uploaded.

Are my photos uploaded to a server?

No. The HEIC is decoded and re-encoded entirely in your browser with a built-in WebAssembly decoder; the photo never leaves your device. This is the core design principle of the tool.

WebP keeps files smaller than JPEG at a similar quality and supports transparency, while being supported by every modern browser — a good balance of size and compatibility for the web.

HEIC (High Efficiency Image Container, using HEVC/H.265) is the format iPhones save by default since iOS 11. It stores smaller files than JPEG, but many apps and older Windows versions can't open it — converting fixes that.

Is converting HEIC to WebP free?

Yes — converting iPhone HEIC/HEIF photos to the compact WebP format is completely free, forever. No account, no sign-up, and no limit on how many photos you convert. The HEIC is decoded by a built-in WebAssembly (libheif) decoder and re-encoded as WebP entirely in your browser; your photos are never sent to any server. The site is ad-supported.

Does it work offline?

Yes. The decoder is bundled into the page, so after it loads no server connection is needed and it works offline.

Why does conversion take a moment?

HEIC decoding runs as single-threaded WebAssembly on your device. A typical 12-megapixel photo decodes in about 1–3 seconds; very large images take a little longer.

Convert HEIC to WebP

HEIC to WebP is a free browser-based tool that converts Apple HEIC/HEIF photos (the iPhone default) into compact WebP images. The HEIC is decoded on your device with a built-in libheif WASM decoder — no upload, no account — then re-encoded to WebP, which keeps files small while staying widely supported on the web. It works offline.

HEIC has been the iPhone default photo format since iOS 11 (2017) and typically stores images at roughly half the size of an equivalent JPEG.
WebP achieves roughly 25–34% smaller files than JPEG at equivalent visual quality, per Google's WebP studies.
libheif is the open-source library that decodes HEIF/HEIC; compiled to WebAssembly it runs entirely in the browser with no server.
WebP supports both lossy and lossless modes and an alpha channel, and is supported by all current major browsers.
Because decoding happens client-side, the photo is never transmitted, keeping personal images private.
