About this tool
HEIC (High Efficiency Image Container) is the photo format iPhones save by default. It's smaller than JPG at similar quality, but plenty of websites, forms, and non-Apple apps don't accept it. This tool decodes the HEIC file and re-encodes it as a standard JPG, entirely in your browser — nothing is uploaded to a server.
How to use the HEIC to JPG Converter
- Choose a HEIC photo — usually from an iPhone or synced from iCloud.
- Wait a moment while it decodes — larger photos take a few seconds.
- Preview and download the converted JPG.
How the conversion works without uploading
Most online HEIC converters send your photo to their server, convert it there, and send a JPG back. This page does the whole job on your device instead: the photo you pick is read locally by your browser, decoded by a HEIC decoder that loads as part of this page, redrawn, and saved as a JPG at 90% quality, which you download straight from memory. No request carrying your photo is made. That matters for private photos — IDs, documents, family pictures — and it also means there is no upload wait on a slow connection. If you want to check for yourself, open your browser's developer tools, switch to the Network tab, and convert a photo: nothing is sent.
Common use cases
- Uploading an iPhone photo to a website or form that only accepts JPG or PNG
- Sending a photo to someone whose device or app can't open HEIC files
- Attaching an iPhone photo to an email through a client that displays HEIC as a blank icon
Why iPhones use HEIC in the first place
Apple switched to HEIC as the default photo format starting with iOS 11 because it compresses more efficiently than JPG — roughly half the file size at a similar visual quality, which matters when a phone's storage fills up with thousands of photos. The trade-off is compatibility: JPG has been a universal standard since the 1990s, while HEIC support outside Apple's own ecosystem is still inconsistent across older software, some Android devices, and various web forms.
Things to watch out for
If you'd rather avoid this conversion step entirely going forward, your iPhone can save future photos directly as JPG: Settings → Camera → Formats → "Most Compatible" (instead of "High Efficiency"). This doesn't affect photos already taken — those stay in HEIC until converted. Converting HEIC to JPG involves a small amount of re-compression, so for photos you plan to edit heavily or print large, keeping a copy of the original HEIC file alongside the converted JPG is worth doing if storage space allows.

Frequently asked questions
HEIC is Apple's default photo format since iOS 11. It compresses more efficiently than JPG, so photos take up roughly half the storage space at similar visual quality — but many non-Apple apps, websites, and older software don't accept HEIC files directly.
There's a small quality trade-off, since HEIC and JPG use different compression methods, but at a high JPG quality setting the difference is generally not noticeable to the eye.
No. The conversion runs entirely in your browser using JavaScript. Your photo is never uploaded or stored anywhere.
