Source Format

PPM Image

PPM (Portable Pixmap Format) is a simple, uncompressed color image format belonging to the Netpbm family. It stores RGB pixel data in a straightforward human-readable ASCII or more compact binary format with a minimal header. PPM is valued for its extreme simplicity, making it easy to generate and parse programmatically.

Advantages

  • Extremely simple format that is easy to read and write programmatically
  • No compression means no quality loss whatsoever
  • Portable across different platforms with no library dependencies

Limitations

  • Very large file sizes due to no compression
  • No support for alpha transparency or metadata
  • Not practical for storage or distribution of images

Common Uses

  • Intermediate format in image processing pipelines and scripts
  • Teaching and learning image processing fundamentals
  • Simple data exchange between command-line image tools

Target Format

HEIC Image

image/heic

HEIC (High Efficiency Image Container) is a container format based on the HEIF standard that stores images compressed with the HEVC (H.265) codec. It is the default photo format on Apple devices running iOS 11 and later, offering roughly 50% file size reduction compared to JPEG at similar quality. HEIC supports advanced features including image sequences, depth maps, and auxiliary data.

Advantages

  • Approximately 50% smaller file sizes compared to JPEG at equivalent quality
  • Supports 16-bit color depth, alpha transparency, and depth maps
  • Can store multiple images, live photos, and burst sequences in a single file

Limitations

  • Limited support on Windows and Android without additional codecs
  • HEVC codec is subject to patent licensing requirements
  • Not supported by most web browsers for direct display

Common Uses

  • Default photo format on iPhones and iPads
  • Space-efficient photo storage on Apple devices
  • Live Photos and burst sequences on iOS
