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.

Frequently asked questions

How do I convert HEIC to JPG?
Drop your HEIC photos onto the box above (or click to choose them), pick a quality, and download the JPGs. The conversion runs on your own device in the browser, so there's nothing to install and no account to create.
Does ConvertCabin upload my photos?
No. The conversion happens entirely inside your browser using a local copy of the libheif engine. Your photos are never sent to a server, and the tool keeps working even if you go offline after the page loads.
Why are my iPhone photos in HEIC format?
Recent iPhones save photos as HEIC by default because it stores the same quality in roughly half the file size. The trade-off is that many apps and Windows programs can't open HEIC, which is why converting to JPG makes them universally viewable.
Can I convert HEIC on Windows without installing software?
Yes. This works in any modern browser on Windows, Mac, Linux, Android or iPhone — no software, plugin or account required. Just open the page and drop your files.
Is there a file size or batch limit?
There are no server-imposed limits because nothing is uploaded. You can convert many photos at once; the only practical ceiling is your device's memory.
Does converting to JPG reduce quality?
JPG is a lossy format, so there's some compression, but at the default 90% quality the difference is hard to see. Lower the slider for smaller files or raise it to keep maximum detail.
What is a HEIC file?
HEIC (High Efficiency Image Container) is the format iPhones and iPads have used to save photos since iOS 11. It stores the same quality as JPG in roughly half the space, but many Windows apps and websites can't open it natively, which is why it's often converted.
What is a JPG file?
JPG (also written JPEG) is the most widely supported image format on the web. It uses lossy compression to keep files small, making it ideal for photos and sharing, though re-saving repeatedly slowly reduces quality.
Why are my photos HEIC instead of JPG?
iPhones and iPads save photos as HEIC by default since iOS 11 because it stores the same quality in about half the space. You can change it in Settings → Camera → Formats → Most Compatible, or just convert the HEIC files you need to share.
Is HEIC better than JPG?
For storage, yes — HEIC holds the same quality at roughly half the file size. For compatibility, JPG wins: it opens everywhere, while HEIC support is still patchy outside Apple devices. That trade-off is why converting HEIC to JPG is so common.
