Features
Smaller Files, Same Quality
H.264 re-encoding with a smart CRF preset strips redundant data while preserving what the eye actually notices.
Up to 80% Smaller
Typical MP4 recordings shrink to 20–30% of original size with no visible quality drop.
Adjustable Quality
Pick a preset from Maximum Compression to Visually Lossless — preview the size before you download.
