Output lanes by destination
Separate submission, publishing, and editing needs so the same conversion lands cleanly.
Publish
Use 85-95 for comparisons and 100 when testing lossless-style output. With PNG, transparency and pixel fidelity matter more than camera metadata.
Edit or archive
Export logos/UI assets at their actual display size; screenshots should match the content width. Keep the original PNG separately when it matters.
