Aggressive compression tradeoffs
Compressing large photos under strict 20 KB or 50 KB limits involves aggressive lossy optimization and resolution downscaling. Inspect the preview image to confirm facial details and text remain legible before uploading to official portals.
Standard: Iterative canvas quantization runs 100% on-device in browser memory; original image files are never uploaded.
