Understanding HEIF and PPM Formats

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

Source 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

Target Format

PPM Image

image/x-portable-pixmap

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
