How the Processing Engine Works
Reaching a precise 100KB target requires an algorithmic balance. Our client-side engine executes a binary search across JPEG quantization tables (evaluating qualities between 5% and 95%). If the image is extremely complex (e.g. detailed foliage or high-ISO noise) and cannot reach 100KB at acceptable quality, it gently downscales pixel dimensions to guarantee compliance.
Balancing Quality, Dimensions & Target Size
What if your JPG cannot reach 100KB through quality alone? If a 10MB photo is forced into 100KB purely through JPEG quantization, ugly macroblocking and color banding appear. SnapReduce instead intelligently combines modest dimension scaling (e.g. from 4000px down to 1800px) with clean quality encoding, ensuring your document remains crystal clear.
