Convert Image to JPG

Core Goal

  • Convert one local image or a directory tree of local images into .jpg.
  • Write JPG DPI metadata as 96 by default or a caller-provided value.
  • Preserve relative directory structure when the input path is a directory.

Required Tools

  • Use scripts/converttojpg.py.
  • Rely only on Python standard library modules. Do not install Python packages for this skill.
  • Prefer magick when it is installed.
  • Fall back to macOS sips when magick is unavailable.
  • Stop and report the missing dependency when neither backend exists.

Quick Start

  1. Convert one file to a specific JPG path:
python3 scripts/convert_to_jpg.py \
  --input-path /path/to/image.heic \
  --output-path /path/to/output.jpg
  1. Convert a directory recursively with custom DPI:
python3 scripts/convert_to_jpg.py \
  --input-path /path/to/input-images \
  --output-path /path/to/output-images \
  --dpi 300
  1. Rewrite existing outputs in place or replace previous runs:
python3 scripts/convert_to_jpg.py \
  --input-path /path/to/input-images \
  --output-path /path/to/output-images \
  --overwrite
  1. Preview the conversion plan without writing files:
python3 scripts/convert_to_jpg.py \
  --input-path /path/to/input-images \
  --output-path /path/to/output-images \
  --dry-run

Behavior

  • Treat directory input as recursive and keep the same relative subdirectories in the output tree.
  • Treat single-file --output-path as a directory when it has no .jpg or .jpeg suffix.
  • Convert .jpg and .jpeg inputs too. Use this to normalize output names or rewrite DPI metadata.
  • Default JPG quality to 95.
  • Use the first frame or page when the source format can contain multiple frames, such as GIF or TIFF.
  • Refuse ambiguous directory conversions when two source files would map to the same destination .jpg.
  • Add uncommon extensions with --extra-extension .ext when needed.

Main Arguments

  • --input-path: source file or source directory
  • --output-path: output JPG file path or output directory
  • --dpi: target DPI metadata for the JPG output, default 96
  • --quality: JPG quality from 1 to 100, default 95
  • --backend: auto, magick, or sips
  • --extra-extension: additional directory-scan suffix to include
  • --overwrite: replace existing outputs
  • --dry-run: print the plan without converting files
  • --limit: cap the number of files processed during a quick check

Script

  • scripts/converttojpg.py
