HEIC is the photo format every iPhone has used by default since iOS 11, valued for being roughly 40 to 50 percent smaller than an equivalent JPG at similar quality thanks to its HEVC-based compression. The catch is compatibility: HEIC relies on patented HEVC decoding, which means many web apps, email clients, older Windows programs, and some browsers simply can't open it, even though it displays perfectly fine on the iPhone that took the photo.
Converting to JPG trades away some of HEIC's storage efficiency and its 10-bit color depth in exchange for a format that opens absolutely everywhere without needing any special codec installed. This is the most common reason people need to convert HEIC files at all — moving iPhone photos to a Windows PC, an older application, or a platform that hasn't added HEIC support.
- Install Turbo Batch Image Converter Pro on your Windows PC. No HEVC codec installation is required.
- Open the app and select Batch Mode for a full photo library, or Individual Mode for a single HEIC file.
- Drag your HEIC photos or folder into the app, enabling recursive folder scanning for nested backup folders.
- Set the "From" format to HEIC and the "To" format to JPG.
- Adjust the JPG quality setting to balance file size against image clarity.
- Click Convert. The app decodes each HEIC file locally and writes JPG files to your output folder, fully offline.
- Fully offline — your personal iPhone photos never leave your PC
- Bulk-convert an entire photo library backup in one batch
- Recursive sub-folder support for nested photo library structures
- No HEVC codec or special viewer required to convert
- Multi-core processing for fast handling of large photo libraries
- Option to delete original HEIC files automatically after conversion
Why do my iPhone photos show up as HEIC on Windows?
iPhones save photos as HEIC by default since iOS 11 to save storage space, but Windows and many other platforms expect JPG, which is why conversion is often necessary after transferring files.
Will I lose quality converting HEIC to JPG?
Some quality is traded for compatibility since JPG caps out at 8-bit color compared to HEIC's 10-bit, though the visible difference is minimal on most displays and at a high quality setting.
Can I convert my entire iPhone camera roll at once?
Yes, Batch Mode with recursive sub-folder scanning is designed for exactly this, converting large, nested photo collections in a single run.
