What is a HEIC file?
HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads since iOS 11. It is based on the HEVC video codec and stores photos at roughly half the size of JPG with similar quality. The problem is compatibility: Windows, many Android phones, older Mac apps and most websites cannot open HEIC files without extra software.
Converting to JPG solves this immediately. JPG is supported by every device, browser, editor, printer and upload form in the world. Read more in our guide What is HEIC and how to open it.
Bulk conversion without uploading
Most online converters upload your photos to a server, convert them there and make you download them again. That is slow and not great for personal pictures. This converter works entirely in your browser: the HEIC decoder is loaded once, and every photo is converted locally on your own device. You can select hundreds of photos and download them all as a single ZIP file.
Choosing the right quality
- 92% (default) — excellent quality, visually identical to the original.
- 80% — about half the size, still very good for sharing and websites.
- PNG — lossless but large; use it only if you plan to edit the image further.
Stop your iPhone from saving HEIC
Open Settings → Camera → Formats and choose Most Compatible. New photos will be saved as JPG. Alternatively, keep HEIC to save space and convert only the photos you need to share.
