About this site
This site does one job: it converts HEIC and HEIF photos — the format
iPhones save by default — into JPEG, PNG or a simple PDF, entirely
inside your web browser. It exists because that job comes up
constantly for ordinary people (a form that refuses
.heic, a Windows PC that will not preview iPhone
photos), and because most of the tools offering to help want you to
upload your photos to their servers first.
The one design decision that matters
Everything here runs on your device. When you drop a photo, an open-source decoder compiled to WebAssembly turns it into pixels in your browser’s memory, and the JPEG, PNG or PDF is built in the same tab. There is no upload step, no account, and no server-side processing of your pictures. You can watch this yourself: load the page, disconnect from the internet, and the converter keeps working.
That decision shapes what the site can and cannot promise. It cannot offer cloud storage, sharing links, or conversion on a device too old to run WebAssembly. In exchange, the privacy claim is structural rather than a policy promise: the code that would send your photos anywhere simply is not there. The privacy page describes the small print, including what any web host sees in ordinary access logs.
How it is funded
Hosting is paid for by advertising served through Google AdSense. The ad network sees ordinary page-visit information, as any advertising script does; it does not receive the photos you drop, which never leave your device. There are no affiliate links, no sponsored recommendations, and no paid tier — the converter is the whole product, and it is free.
The software it stands on
Decoding is done by heic-to, which bundles libheif, the widely used open-source HEIF/HEIC library. Both are licensed under the GNU Lesser General Public Licence, and copies of the notices ship with this site. The PDF builder and the rest of the page are plain JavaScript written for this site. Credit for the hard part — decoding a patent-encumbered image format correctly — belongs to those projects and their contributors.
Who operates it
The site is independently operated from the United Kingdom. It is written in UK English, which is why you will find “licence” and “colour” in the guides. The converter and the accompanying guides — HEIC to JPEG on Windows, HEIC to PDF for forms, HEIC to PNG and why iPhone photos are HEIC — are all first-hand descriptions of how this tool behaves, not rewrites of other people’s articles.
