flatten alpha predictably before JPEG compression. Process the visible sample or your own image before continuing to the exact full-tool setup.
- 01
Add the family sample or your image
Use a supported static image for this flatten alpha predictably before JPEG compression.
- 02
Review the configured behavior
Transparent pixels are flattened onto white before the 84% JPEG encode.
- 03
Process and inspect the result
The measured output, warnings, and limitations come from the active canonical executor.
Know the boundaries before processing
Results depend on source pixels, browser support, format behavior, and the visible settings.
