About HEIC2JPGFree

Why this site exists

The HEIC compatibility problem is mundane but constant: a photo works perfectly on an iPhone, then gets rejected by a web form, an old laptop or a business system. The standard fix — an online converter that uploads your photo, processes it remotely and mails you a link — solves the format problem by creating a privacy one.

HEIC2JPGFree takes the other route. Modern browsers are powerful enough to decode HEIC themselves, using an open-source decoder (libheif) compiled to WebAssembly. So that is what every tool on this site does: your file is read by JavaScript in your own browser tab, converted in memory on your own device, and offered back as a download. The "uploaded: 0 bytes" meter on each tool isn't marketing — it is a description of the architecture, and you can verify it in your browser's network inspector.

What the site can and cannot do

Can: convert HEIC/HEIF to JPG, PNG, WEBP and PDF; compress and resize JPG, PNG and WEBP; process batches up to 20 files and bundle results into a ZIP — all offline-style, in the browser.

Cannot: decode every exotic HEIC variant (some 10-bit HDR and burst containers exceed what browser decoders support), process files over 25 MB (browser memory limits), or edit photos. When a file fails, the tool says so honestly instead of producing a broken download, and the failed-conversion guide explains the likely cause.

How the site is funded

The tools are free, with no account, watermark or daily limit. The site is supported by advertising on its pages. Ads never interfere with the conversion itself, and because conversion is local, advertisers never see your images — no one does, including us.
