About Video Compressor
Make a video file smaller so it fits an email attachment, an upload limit or a chat app, without installing anything.
What makes a video large
File size depends mainly on three things: resolution (1080p, 720p, 480p), bitrate (how much data is used for each second of video) and length. A one-minute phone video in 4K can easily be several hundred megabytes, while the same clip at 720p may be a small fraction of that.
Getting the best result
Lowering the resolution to 720p is usually the biggest saving with the smallest visible loss on a phone screen. Very long recordings will always be large, so trimming the parts you don't need first saves more than squeezing the quality. Screen recordings and talking-head videos compress far better than fast action, which needs a lot of data to look sharp.
Quality vs size
Every compression removes some detail. Compress once from the original file rather than compressing an already-compressed copy again, because the losses add up each time and the video starts to look blocky.
Privacy
Your video is processed on our server only to make the smaller file and is deleted automatically afterwards.
For sharing, also consider sending a link from a cloud drive instead of the file itself — there is no size limit and no quality loss. To change the format rather than the size, see MOV to MP4 or MKV to MP4; to pull out only the sound, MP4 to MP3.
