Why Compress MP4 Files?
MP4 is the universal video format, but recordings from phones and cameras use high bitrates that make files huge. Compression re-encodes the video to a sensible bitrate, cutting size by up to 80% for easy sharing and streaming.
How MP4 Compression Works
Our tool re-encodes with efficient H.264/H.265 and tunes the bitrate to balance size and clarity. You can keep the original resolution and frame rate, or reduce resolution for even smaller files.
Bitrate, Resolution, and File Size
File size is driven mostly by bitrate and resolution. Lowering bitrate alone often saves a lot; dropping a 4K clip to 1080p saves even more while still looking great on most screens.

Cloud-powered processing delivers results in seconds, not minutes.
Bank-Level Security
256-bit SSL encryption. All files automatically deleted after 1 hour.
