How to Convert HEIC to JPG on iPhone

Need to upload photos to a website or share with a Windows user, but your iPhone photos are in HEIC format? Here is how to batch convert them.

Quick Answer

iPhones capture photos in Apple's high-efficiency HEIC format to save storage. However, HEIC images often fail to open on Windows PCs or upload to online forms. To convert HEIC to JPG on your iPhone, you can use the secure, free Compress app to batch-transcode photos offline in seconds. Alternatively, you can copy-paste files into the built-in iOS Files app (which automatically translates them to JPEGs) or adjust your camera settings under Settings > Camera > Formats to 'Most Compatible' for future shots. For existing library images, Compress is the simplest offline tool.

FAQ

Common Questions

Why are my iPhone photos saved as HEIC instead of JPG?

Apple uses the HEIC (High Efficiency Image Container) format by default because it compresses photos up to 50% better than standard JPEGs. This helps save local iPhone storage space without compromising image quality.

Does converting HEIC to JPG reduce photo quality?

Converting formats does not result in a noticeable drop in visual quality. Using the Compress app, HEIC files are transcoded into highly optimized, high-fidelity JPEGs, ensuring they look identical while becoming universally compatible.

Can I set my iPhone to shoot in JPG format directly?

Yes. Go to Settings > Camera > Formats and select 'Most Compatible'. This forces your iPhone camera to save new captures directly in JPEG format. Note that this will increase the storage space needed for each photo by about double.
