How it works
ConvertCabin loads a local copy of libheif — the open-source engine that decodes Apple's HEIC format — and runs it inside your browser tab. When you add a photo, it's decoded and re-saved as a JPG right there on your machine, then offered back to you as a download. No part of the file is sent anywhere.
That's the whole pitch: most online converters upload your photos to their servers, queue them, and cap your free usage. Because ConvertCabin does the work on your device, it can stay genuinely free, unlimited, and private — and it keeps working even with no connection once the page has loaded.
About HEIC and JPG
HEIC (High Efficiency Image Format) is what modern iPhones use by default. It packs great-looking photos into about half the space of a JPG, which is excellent for your phone's storage — but awkward the moment you try to open one on Windows, attach it to an older app, or upload it somewhere that only accepts JPG. Converting to JPG trades a little file size for the ability to open the image absolutely anywhere.
