PikPix is a versatile command-line tool designed to convert and optimize image formats with optional compression, resizing and optimizations. To learn more about the technologies used to build PikPix, refer to the Acknowledgements section at the bottom of this README.

• Image Conversion: Supports various formats including heic, heif, avif, jpeg, jpg, png, raw, tiff, tif, webp, gif, jp2, jpx, j2k, j2c, and svg.
• Compression Level: Specify compression level (quality) for formats like jpeg, jpg, png, webp, tiff, heif, heic, and avif.
• Advanced Compression:
  • Lossless Compression: Apply lossless compression for supported formats.
  • Progressive JPEG: Apply progressive compression for JPEG images.
  • Chroma Subsampling: Specify chroma subsampling rate (e.g., 4:2:0, 4:4:4).
  • Adaptive Quantization: Apply adaptive quantization for better compression.
  • Region of Interest (ROI) Compression: Apply compression to specified regions of the image.
• Resizing: Resize images to specified dimensions without cropping.
• Handling Local and Remote Images: Input images from local file paths, URLs, and directories.
• Directory Processing: Process all images in a specified directory.
• Unique Output File Names: Ensures output file names are unique to avoid overwriting.
• Optimization Options: Various optimization features including flattening, sharpening, denoising, converting to grayscale, and applying blur.
• Error Handling: Comprehensive error handling with clear error messages.
• Version Output: Displays the current version of the tool.

To install PikPix, use npm:

npm install -g pikpix

pikpix -i <input> -o <output> -f <format> [options]

• -v, --version: Output the current version.
• -i, --input <path>: Input image file, URL, or directory.
• -o, --output <path>: Output image file or directory.
• -f, --format <format>: Output format (heic, heif, avif, jpeg, jpg, png, raw, tiff, tif, webp, gif, jp2, jpx, j2k, j2c, svg).
• -c, --compression <level>: Compression level (0-100).
• -r, --resize <dimensions>: Resize dimensions in format WIDTHxHEIGHT or WIDTHXHEIGHT.
• --flatten [color]: Flatten the image and fill the background with the specified color (default: white).
• --sharpen: Apply sharpening to the image.
• --denoise: Apply denoising to the image.
• --grayscale: Convert the image to grayscale.
• --blur <sigma>: Apply blur with the specified sigma value.
• --lossless: Apply lossless compression if supported by the format.
• --progressive: Apply progressive compression for JPEG images.
• --subsample <rate>: Apply chroma subsampling rate (e.g., 4:2:0, 4:4:4).
• --adaptive-quantization: Apply adaptive quantization for better compression.
• --roi-compression <regions>: Apply region of interest (ROI) compression to specified regions.
