Convert and choose quality

Write PNG, JPEG, WebP, or supported HEIC output and control lossy quality.

Pipeline v1View source Read the docs

Convert chooses the output encoder. Rastry accepts and writes PNG, JPEG, and WebP on every platform. HEIC input and output use the operating-system codec on macOS and Windows; Linux hides HEIC in Desktop and cannot provide that conversion path.

CLI example

Terminal window
rastry photo.png --to webp --quality 82 --dry-run

The shorthand adds a conversion operation and then strips metadata. A quality value is an integer from 1 to 100 and is relevant to JPEG, WebP, and HEIC output when the host encoder accepts it. PNG is lossless and does not use a quality setting.

Pipeline example

{
  "type": "convert",
  "format": "webp",
  "quality": 82
}

Choose PNG when lossless transparency matters, JPEG for opaque photographic output, WebP when broad modern web delivery is the goal, or HEIC when the target workflow supports the system codec.
