Frequently Asked Questions

How do I compress an MP4 file?
Upload your MP4, choose a quality preset (Small for maximum compression, Balanced for a good middle ground, or High Quality for minimal compression), and click Process.
How much smaller will the MP4 be?
It depends on the original encoding. Poorly compressed videos can shrink 80-90%. Already optimized files may shrink 30-50%. The Small preset gives maximum compression.
