HEIC uses HEVC-based compression that significantly outperforms PNG's lossless storage for file size, and it supports an alpha channel, so transparency from a PNG can carry over to the converted file. For large libraries of PNG screenshots or graphics where storage space matters more than universal compatibility, converting to HEIC can meaningfully reduce disk usage, often by a wide margin compared to the original PNG.
HEIC also supports 10-bit color depth, beyond what PNG typically stores for everyday images, though this only matters if your source content actually has that level of color precision to begin with. The main consideration before converting is compatibility — HEIC is well supported on modern Windows, macOS, and recent software, but some older programs and platforms still expect more universal formats like PNG or JPG.
- Install Turbo Batch Image Converter Pro on your Windows PC.
- Open the app and select Batch Mode for multiple files, or Individual Mode for a single PNG.
- Drag your PNG file or folder into the app window, enabling recursive folder scanning if needed.
- Set the "From" format to PNG and the "To" format to HEIC.
- Adjust the quality setting to balance file size against visual detail.
- Click Convert. HEIC files are written to the output folder, fully offline.
- 100% offline — your images are never uploaded anywhere
- Bulk conversion of entire folders, including sub-folders, in one pass
- Significant storage savings for large PNG archives
- Multi-core processing for fast handling of large batches
- Option to delete original PNG files automatically once converted
- No recurring subscription or hidden upload limits
Will my transparent PNG stay transparent in HEIC?
Yes, HEIC supports an alpha channel, so transparency present in the original PNG can be preserved in the converted file.
Does converting to HEIC reduce image quality?
HEIC typically uses lossy compression, so some quality is traded for the smaller file size compared to PNG's lossless storage, though at a higher quality setting the visible difference is often minimal.
Will HEIC files open on older software?
Most current operating systems and recent software handle HEIC without issue, but some older programs may still expect a more universal format, so it's worth checking compatibility with your intended use case.
