How to Convert HEIC to PNG Without Online Upload

HEIC is the default photo format on modern iPhones and some Android devices. It compresses well, but a lot of Windows software, older editing tools, and web platforms still don't open it properly. PNG is universally supported and lossless, which makes it a dependable target format when you need your iPhone photos to open cleanly everywhere, especially for graphics, screenshots, or images you intend to edit further.

Most "HEIC to PNG converter" sites ask you to upload your photos to their server first. That's a privacy concern for personal photos, and it's painfully slow once you have more than a handful of images. Converting offline with a desktop app avoids both issues entirely.

1. Download and install Batchify Image Converter and Resizer Pro on Windows. No account or internet connection is needed to convert your files.
2. Open the app and choose Batch Mode if you're converting a whole photo library, or Individual Mode for a single HEIC file.
3. Drag in your HEIC photos or the folder containing them. Enable recursive sub-folder scanning if your iPhone backup is organized into dated folders.
4. Set "From" to HEIC and "To" to PNG.
5. Optionally resize your images during the same step if you want smaller dimensions for sharing or storage.
6. Click Convert. The app decodes each HEIC file locally and writes standard PNG files to your output folder — nothing is ever uploaded.
