HEIC's HEVC-based compression makes it an efficient format for everyday iPhone photos, but it's a lossy format, while PNG is lossless and far more universally supported by editing tools, browsers, and graphics software. If you've screenshotted something on an iPhone that saved as HEIC, or you need to bring an iPhone photo into an editing workflow where you want to avoid introducing further compression loss, converting to PNG is the better target than JPG.
PNG also supports a full alpha channel, which matters if your HEIC source has any transparency-related editing applied — though most everyday iPhone camera photos won't have transparency to begin with, since that's primarily a feature relevant to graphics and edited images rather than typical photography.
- Install Turbo Batch Image Converter Pro on Windows. No account or internet connection is needed to convert.
- Open the app and choose Batch Mode for a whole photo library, or Individual Mode for one HEIC file.
- Drag in your HEIC photos or folder, enabling recursive sub-folder scanning for dated backup folders.
- Set "From" to HEIC and "To" to PNG.
- Click Convert. The app decodes each HEIC file locally and writes standard PNG files to your output folder.
- Fully offline conversion — your personal photos never leave your PC
- Lossless PNG output avoids introducing further compression artifacts
- Bulk-convert entire iPhone photo backups in one batch
- Recursive folder support for nested photo library structures
- Multi-core processing for fast conversion of large photo libraries
- Option to delete original HEIC files automatically after conversion
Why choose PNG instead of JPG for HEIC conversion?
PNG is lossless, so it's a better choice when you want to avoid any further compression artifacts during editing, while JPG is better suited to smaller, easily shareable files.
Will my converted PNG be larger than the original HEIC?
Usually yes, since HEIC's HEVC-based compression is quite efficient, and PNG's lossless storage generally takes up more space for the same image content.
Can this handle my entire iPhone photo backup at once?
Yes, Batch Mode with recursive sub-folder scanning is designed for exactly this, converting large, nested photo collections in a single run.
