Why Pre-Compressing Matters
Many government submission portals, job application forms, customer support ticket systems, and legacy email gateways enforce a strict, unyielding 10MB maximum file size limit. VideoReduce calculates the exact two-pass video and audio bitrate allocation required to guarantee your output file finishes at 9.5MB while maximizing visual sharpness.
