Shrink any video to exactly the size you need. Fast Video Compress takes a video that is too big to send and compresses it to a target size you choose — 25 MB for email, 100 MB for chat apps, whatever your limit is — with one slider and one button. TARGET SIZE, NOT GUESSWORK Other tools make you guess bitrates and formats. Fast Video Compress works backwards from the answer: tell it the size you want, and it calculates the optimal video bitrate for your clip's length, shows you the estimate, and delivers a file that fits. No math, no trial and error, no oversized rejects.
