HEIC to WebP Converter

Runs in your browser — your files are never uploaded.

Convert iPhone and iPad HEIC photos straight to WebP. If the photo is headed for a website, this is the conversion you actually want: WebP keeps files roughly as small as HEIC while being readable by every browser, where HEIC is readable by almost none. The decode runs on a WebAssembly build of libheif inside your browser — your photos never leave your device.

Frequently asked questions

Why WebP instead of JPG?+

File size. At the same visual quality WebP is typically 25–35% smaller than JPEG, which is the whole point if the image is going on a web page. Choose HEIC to JPG instead if the file is going into an app or document rather than a website.

Why does it say my browser can’t encode WebP?+

Creating WebP files in the browser is a Chromium feature — Chrome, Edge, Opera and Brave. Firefox and Safari display WebP happily but cannot produce it, so use HEIC to JPG or HEIC to PNG there instead.

Are Live Photos supported?+

The still image is converted, which is what you want for the web. The short video an iPhone attaches to a Live Photo is stored separately and is not included.

Why is the first conversion slow?+

HEIC decoding needs a WebAssembly build of libheif, about 3 MB, loaded the first time you use a HEIC tool. It stays cached for the rest of your session.

Are my photos uploaded?+

No. Decoding and re-encoding both happen on your device. Your photos are never uploaded, stored, or logged.
