What Is a HEIC to PNG Converter?
A HEIC to PNG converter transforms iPhone photos into lossless PNG format with full color preservation. Unlike JPG conversion, HEIC to PNG is lossless — the decoded HEIC pixel data is stored exactly in PNG. This is ideal for editing or archiving iPhone photos without any additional quality loss.
Why Convert HEIC to PNG?
PNG is the preferred format for image editing (no generation loss), graphics with transparency, and lossless archival. Converting HEIC to PNG creates a universally editable file that preserves the full decoded quality of your iPhone photos.
Best For:
- Editing iPhone photos in Photoshop, GIMP, or Canva
- Archiving iPhone photos in lossless format
- Adding transparency to iPhone photo edits
- Professional design work from iPhone source
Technical Details
TweakFiles uses libheif 1.21 to decode HEIC, then encodes as lossless PNG. Files will be significantly larger than HEIC (3–10x) since PNG uses lossless compression versus HEIC's lossy compression. This preserves the decoded quality without adding any JPG-style compression.
