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. For web delivery, Exif is usually off; for asset management, keep only what you need.
Edit or archive
Match the image to the 1x/2x display slot and resize oversized web assets before exporting. Keep the original WebP separately when it matters.
Route readout
WebP friction
Common for downloaded web assets and CMS images because it is designed for delivery. Some editors, submission forms, and email previews still handle it poorly.
JPEG XL endpoint
JPEG XL/JXL is useful for archiving, comparison, and migration experiments. Best for image archives, next-generation format checks, and JXL-capable workflows.
