Keep the quality.
Stop guessing compression sliders. Tell EXACT the maximum file size and it searches quality, dimensions and browser-native image encoders locally until the best candidate fits beneath the ceiling.

EXACT evaluates useful dimension levels and binary-searches lossy encoder quality to find candidates that actually fit.
AUTO keeps transparent sources on alpha-capable formats. JPEG flattening is an explicit review choice, never a hidden optimization.
Use the recommended balance or choose a candidate that protects dimensions or encoder quality more aggressively. The numbers stay visible.
