Technical Architecture & In-Browser Processing
A 16MB allocation supports long 1080p Full HD video clips with vibrant color reproduction and pristine acoustic definition. FitSize utilizes high-profile AVC encoding with deblocking loop filters to preserve texture detail in foliage, clothing, and water. Because the entire pipeline runs locally via WebCodecs, you can compress sensitive recordings without transmitting footage across public networks.
Calibrated directly against WhatsApp's native media payload limit, 16MB preserves maximum visual punch without triggering WhatsApp's lossy cloud re-transcoder. By keeping the average bitrate inside safe structural thresholds and normalizing audio loudness to -14 LUFS, your video arrives on recipient smartphones crisp, vibrant, and ready for immediate full-screen viewing.
