HEIC to JPG: The Complete iPhone Photo Guide for 2026
You AirDrop a photo from your iPhone, email it to a colleague, or upload it to a form — and it simply won't open. The culprit is almost always HEIC, Apple's space-saving photo format. It's brilliant for storage but a constant source of friction the moment a file leaves the Apple ecosystem.
This guide explains what HEIC is, why it breaks on so many platforms, when and how to convert to JPG, and how to stop your iPhone from creating HEIC files in the first place.
HEIC to JPG
Convert iPhone HEIC photos to standard JPG.
What is a HEIC file?
HEIC (High Efficiency Image Container) is the default photo format on modern iPhones and iPads. It uses the HEIF standard to store photos at roughly half the size of JPG at similar quality, which saves a lot of space on your device and in iCloud.
The trade-off is compatibility: while Apple devices handle HEIC seamlessly, many other platforms still don't.
Why HEIC won't open on Windows and Android
HEIC support outside Apple is inconsistent. Some Windows and Android versions need extra codecs or apps to view HEIC, many web upload forms reject it, and plenty of editors and older devices can't read it at all. Converting to JPG sidesteps every one of these problems, because JPG opens essentially everywhere.
When to convert HEIC to JPG
- You're sending photos to someone on Windows or Android.
- A website or application only accepts JPG/JPEG uploads.
- You want to edit the photo in software that doesn't read HEIC.
- You're archiving photos in a universally compatible format.
How to stop your iPhone saving HEIC
If HEIC keeps causing problems, change the capture format. On your iPhone, open Settings → Camera → Formats and select 'Most Compatible' to shoot JPG directly. New photos will be JPG from then on; existing HEIC photos still need converting.
Converting privately, with no app
Most online HEIC converters upload your photos to a server — a real privacy concern for personal pictures. PixelResize decodes HEIC in your browser using WebAssembly, so the conversion happens entirely on your device. Drop in a .heic or .heif file, preview the JPG, and download it. It works on any device, including Windows and Android, with no Apple software required.
Key takeaways
- HEIC is Apple's space-saving photo format and isn't supported everywhere.
- Convert to JPG when sharing with non-Apple devices, uploading, or editing.
- Set your iPhone camera to 'Most Compatible' to capture JPG directly.
- Browser-based conversion keeps personal photos private — nothing is uploaded.
