Key Capabilities
Smart Lossy & Lossless Algorithms
Automatically analyzes color distribution and edge frequency to discard imperceptible data while preserving sharp outlines.
True Web Worker Concurrency
Calculations occur in background threads, so your browser stays responsive even when crunching 50+ images simultaneously.
Precise Target Constraint
Specify an upper byte ceiling (e.g. 200KB or 1MB) and the engine dynamically iterates until the payload falls under the threshold.
