Release Notes

First changelog-tracked release. Includes all features built since v0.1.0.

Features

• compress — one-command web optimization: resize + format convert + compress with --max flag. Auto-naming (photo.min.jpg) when -o is omitted. Keeps original if compressed size is larger.
• split — auto-detect and crop individual objects from a sprite/expression sheet. Background color detection, text label exclusion, uniform output sizing with background-color padding, preview with --preview-style detected|output|both.
• favicon — generate a complete web-ready icon set (ICO multi-res + 5 PNG sizes + HTML snippet) from any image.
• remove-watermark — remove Gemini AI watermarks via Reverse Alpha Blending. --if-detected flag to skip clean images.
• detect — score whether a Gemini watermark is present.
• convert — convert between JPEG, PNG, WebP, BMP, GIF, TIFF.
• info — show dimensions, color, EXIF, SHA-256 metadata. --json for machine-readable output.
• install --skills — install a Claude Code skill so coding agents can use pixa automatically.
• Brand palette — all CLI output uses a fixed 24-bit truecolor palette (sage/coral/teal/amber) for consistent appearance across terminal themes. Respects NO_COLOR and FORCE_COLOR.
