Understanding PNG and HEIF Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

PNG Image

image/png

PNG (Portable Network Graphics) is a lossless raster image format that supports full alpha transparency. It was created as a patent-free replacement for GIF and uses DEFLATE compression to reduce file sizes without any loss of quality. PNG is ideal for images that require transparency or need to be edited repeatedly without degradation.

Advantages

  • Lossless compression preserves perfect image quality
  • Supports full alpha transparency with 256 levels of opacity
  • Excellent for graphics with sharp edges, text, and flat colors

Limitations

  • Significantly larger file sizes compared to JPEG for photographic images
  • Does not support animation in standard implementations
  • Not ideal for print workflows that expect CMYK color space

Common Uses

  • Web graphics, logos, and icons requiring transparency
  • Screenshots and user interface elements
  • Graphics with text overlays or sharp geometric shapes

Target Format

HEIF Image

image/heif

HEIF (High Efficiency Image Format) is an image container format standardized by MPEG that can store still images and image sequences using various codecs, most commonly HEVC. It was designed to supersede JPEG by offering better compression, higher quality, and richer features such as image derivations and non-destructive edits. HEIF serves as the underlying standard for Apple HEIC format.

Advantages

  • Superior compression efficiency over JPEG with better image quality
  • Supports non-destructive editing operations stored as metadata
  • Flexible container supporting multiple codecs and image sequences

Limitations

  • Limited native support on Windows and many Linux distributions
  • Codec patent licensing can complicate open-source implementations
  • Not directly supported in web browsers for inline display

Common Uses

  • High-quality photo storage with reduced file sizes
  • Image sequences and derived images in photography workflows
  • Apple ecosystem photo storage and sharing
