Overview

Yara Imcon is a fast, lightweight terminal image converter written entirely in pure Bash. It batch-converts images between common formats — PNG, JPEG, WebP, AVIF, BMP, and TIFF — with optional resize, quality tuning, and metadata stripping. No GUI, no config file, no build step. Just run the script and convert.

Yara Imcon is Version 1.0, released under the MIT License, and built and maintained by Saman Udayanga Wijesinghe as part of the Yara Utility Suite.

Key Features

  • Multi-format conversion — PNG, JPEG, WebP, AVIF, BMP, TIFF input and output
  • Batch processing — convert an entire directory in one command
  • Resize support — scale by pixel dimensions or percentage, fit or fill modes
  • Quality control — per-format quality/compression level flags
  • Metadata stripping — remove EXIF, IPTC, and XMP data for privacy
  • Progress bar — live conversion progress with file count and size delta
  • Dry-run mode — preview what would be converted without writing any files
  • No external dependencies — relies only on ImageMagick (convert), which ships with most Linux distributions
