When Do You Need to Convert HEIC to PNG?
You want an iPhone photo in a lossless format, usually because it is going to be edited, printed, or used somewhere that expects PNG. Converting HEIC to PNG avoids adding a second round of lossy compression on top of what the phone already applied.
What Happens When You Convert HEIC to PNG
Sharp decodes the HEIC and writes a PNG. PNG is lossless, so the conversion adds no further degradation, though the HEIC itself was compressed when the phone saved it and that loss is permanent. Expect the file to grow substantially, frequently by five to ten times, because PNG stores photographic data far less efficiently than HEIC. Transparency is not usually a factor with camera photos, and the picture is written exactly as decoded.
Worth knowing before you convert
Large PNG files are awkward to email and slow to load on a web page. Convert to JPG or WebP for anything that is going to be shared rather than edited.
About HEIC and PNG
image/heic
HEIC is the container format for HEIF (High Efficiency Image File Format) images. Adopted by Apple in iOS 11 and later, it offers better compression than JPEG with higher quality, supporting features like transparency and image sequences.
image/png
PNG is a raster-graphics file-format that supports lossless data compression. It supports palette-based images, grayscale, and full-color non-palette-based RGB or RGBA images. Its most notable feature is support for transparency (alpha channel).
Conversion Notes
Image conversion from HEIC to PNG preserves colour information and dimensions. If PNG uses lossy compression (such as JPEG), compression artefacts appear at lower quality settings — use quality 85+ to minimise visible loss. Transparency (alpha channel) is preserved in formats that support it; if the target format does not support transparency, transparent areas are filled with white by default.
Frequently Asked Questions
PNG when the image will be edited and re-saved, or when software requires it. JPG for sharing and general use, because the file is far smaller and looks the same.
